Welcome to the ServSwitch™ Family!
Thank you for purchasing a BLACK BOX® ServSwitch™ brand console port server!
We appreciate your business, and we think you’ll appreciate the many ways that this
product will save you money, time, and effort.
Our ServSwitch family is all about breaking away from the traditional, expensive
model of device management and display. You know, the one-size-fits-all-even-if-it-
doesn’t model that says, “One computer gets one dedicated monitor or user station, no
more, no less.” Why not a single user station (monitor, keyboard, and mouse) or serial
console for multiple computers, routers, etc.—even computers of different platforms?
Why not a pair of user stations, each of which can control multiple computers? Why
not many monitors or user stations for the same computer? Why not access or display
any of your devices, anywhere in the world, with any of your user stations, monitors,
or consoles?
With our ServSwitch products, there’s no reason why not. We carry a broad line of
robust solutions for all these applications:
• Do you have just two PCs and need an economical alternative to keeping two
mice, keyboards, and monitors on your desk? Or do you need to share many
computers, including a mix of IBM® PC, RS/6000®, Apple® Macintosh®,
Sun Microsystems®, and SGI™ types among multiple worldwide users with
different access levels?
• Do you have to send video from one computer to two different local monitors? Or
do you need to send video from multiple computers to dozens of remote monitors?
• Do you need centralized terminal-based serial control over many sites?
• Does your switch have to sit solidly on a worktable and use regular everyday
cables? Or does it have to be mounted in an equipment rack, use convenient
many-to-one cables, and have a rackmounted user station that folds and slides
into 1U of space?
No matter how large or small your setup is, no matter how simple or how complex,
we’re confident we have a ServSwitch system that’s just right for you. Welcome to the
BLACK BOX ServSwitch™ family—the one-stop answer for all your video, serial
console, and KVM switching and extension needs!

inch rack.
Figure 2-1. SCPS
Serial device access options
Access to attached serial devices is possible via a serial Command Line Interface
(CLI) connection, a PPP (Point to Point Protocol) dial-in connection to a serial CLI
modem or from a third-party Secure Shell (SSH) client.
User authentication and data security
The SCPS user database supports up to 64 user definitions, which include
usernames, passwords and/or keys, plus specifications of access rights to SCPS
ports and commands. User definitions may be changed at any time. You may choose
to have user access authenticated locally at the SCPS user database or at one or
more RADIUS (Remote Access Dial-In User Service) servers. Data security may be
enhanced via industry-standard SSH encryption methods.
Extensive command set
The SCPS offers a wide range of commands that allow administrators to easily
configure, control and display information about the SCPS operating environment,
including its ports, users and device access sessions. The user interface also offers

2.2 Safety Precautions
To avoid potential device problems:
• If the building has 3-phase AC power, ensure that a computer and its monitor (if
used) are on the same phase. For best results, they should be on the same circuit.
• Use only the supplied cable to connect appliances and devices. Warranties do
not apply to damage resulting from user-supplied cable.

SERVSELECT™ IP SCPS INSTALLER/USER GUIDE
10
To avoid potentially fatal shock hazard and possible damage to equipment, please
observe the following precautions:
• Do not use a 2-wire extension cord.
• Test AC outlets at the computer and monitor (if used) for proper polarity
and grounding.
• Use only with grounded outlets at both the computer and monitor. When using
a backup power supply (UPS), power the computer, the monitor and the SCPS
unit off the supply.
NOTE:
The AC inlet is the main disconnect.
Rackmount safety considerations
• Elevated Ambient Temperature: If installed in a closed rack assembly, the
operation temperature of the rack environment may be greater than room ambi-
ent. Use care not to exceed the rated maximum ambient temperature of the unit.
• Reduced Airflow: Installation of the equipment in a rack should be such that the
amount of airflow required for safe operation of the equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven
mechanical loading.
• Circuit Overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might
have on overcurrent protection and supply wiring. Consider equipment name-
plate ratings for maximum current.
• Reliable Earthing: Reliable earthing of rack mounted equipment should be
maintained. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).

Figure 3-1. SCPS Front Panel
The lower left area of the front panel contains five LEDs and two buttons, which are
described in the following table.
SCPS LEDs
LED/Button Description
POWER The POWER LED illuminates when the SCPS is
connected to a power source.
ONLINE The ONLINE LED illuminates steadily (not blinking) when
the SCPS self-test and initialization procedures
complete successfully.
LINK The LINK LED illuminates when the SCPS establishes a
connection to the network.
TRAFFIC The TRAFFIC LED blinks when there is network traffic.
100MBps The 100MBps LED illuminates when the SCPS is
connected to a 100 MBps LAN.

3.2 Installing the SCPS
See Chapter 8 for device cabling information.
WARNING:
The power outlet should be installed near the equipment and should be easily accessible.
To install the SCPS hardware:
1. Locate the SCPS where you can connect cables between the serial devices and
the SCPS serial ports, and where you can connect a LAN interface cable
between the Ethernet hub or switch and the SCPS LAN connector.
If you are using an SCPS Rackmount Kit, follow the instructions included with
the kit.
2. Attach a 10BaseT or 100BaseT LAN interface cable to the LAN connector on the
back of the SCPS. The SCPS requires a CAT 5 cable for 100BaseT operation.
3. Insert the power cord into the back of the SCPS. Insert the other end of the
power cord into a grounded electrical receptacle.
4. Check that the POWER LED is illuminated. If not, check the power cable to
ensure that it is inserted snugly into the back of the SCPS. The ONLINE LED
will illuminate within one minute to indicate that the SCPS self-test is
complete. If the ONLINE LED blinks, contact Technical Support for assistance.
5. Check that the LINK LED is also illuminated. If not, check the Ethernet cable
to ensure that both ends are correctly inserted into their jacks. If the SCPS is
not correctly connected to an Ethernet hub or switch, you will not be able to
configure the SCPS for operation. If the SCPS is connected to a 100 MB
Ethernet hub, the 100MBps LED will also be illuminated.
6. Once the POWER, ONLINE and LINK LEDs are illuminated, remove power
from the SCPS and proceed with the configuration process.
WARNING:
The SCPS and all attached devices should be powered down before servicing the unit. Always
disconnect the power cord from the wall outlet.
3.3 Configuring the SCPS
To configure the SCPS, you must enter a unique IP address and the network’s subnet
mask. This information will be stored in the SCPS configuration database. During
initial login, you will specify a password for the Admin user.

CHAPTER 3: INSTALLATION AND CONFIGURATION
13
Configuring the IP address and subnet mask
You may use any of three methods to configure the SCPS IP address and subnet
mask: BootP, Telnet Command Line Interface (CLI) or the serial CLI on port 1.
These methods work as documented on most Windows and UNIX systems;
however, the actual implementation on your system may differ from the instructions
provided. Refer to your system administrator guide.
To configure the IP address and subnet mask using BootP:
1. Ensure that there is a BootP server on your network that is configured to
correctly respond to a BootP request from the SCPS. BootP servers require the
Ethernet MAC address of network devices. The SCPS Ethernet MAC address is
located on the back panel above the LAN connector. See your BootP server’s
system administrator guide for information about configuring the BootP server.
2. After you have configured your network’s BootP server with the SCPS
Ethernet MAC address, IP address and subnet mask, restore power to the
SCPS and wait for the ONLINE LED to illuminate. Once this occurs, the
SCPS has completed the BootP protocol, obtained its IP address and subnet
mask and stored these in FLASH.
3. You may verify that the BootP process was successful with a ping command,
which tests network connectivity. The ping command is entered as:
ping <ip_address>
For example, the following command tests the network connectivity of an SCPS
with the IP address 192.168.0.5.
ping 192.168.0.5
4. If the SCPS completes the BootP successfully, you will see a display similar to
the following.
Pinging 192.168.0.5 with 32 bytes of data:
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
If the SCPS did not successfully obtain its IP address with the BootP protocol,
you will see a display similar to the following.
Pinging 192.168.0.5 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

SERVSELECT™ IP SCPS INSTALLER/USER GUIDE
14
In this case, check the MAC address and IP address provided to the BootP
server to confirm they are correct. Verify that the Ethernet LAN adaptor cable
is correctly installed on the SCPS and the Ethernet hub.
After the IP address is configured successfully, launch a Telnet session to the SCPS
IP address. Then, see Initial SCPS login in this chapter.
To configure the IP address and subnet mask using a Telnet CLI:
1. Ensure that your server or workstation has a Telnet client and is located on the
same LAN segment as the SCPS.
2. Use the arp command to update the server or workstation with the SCPS IP
address and Ethernet MAC address. The SCPS Ethernet MAC address is
located on the back panel above the LAN connector. The arp command is
entered as:
arp -s <ip_address> <mac_address>
For example, the following command assigns the IP address 192.168.0.5 and
the Ethernet MAC address 00-80-7d-54-01-54 to the SCPS.
arp -s 192.168.0.5 00-80-7d-54-01-54
On a UNIX platform, the MAC address may require colons (:) instead of
dashes (-), for example, 00:80:7d:54:01:54.
3. You may verify that you entered the information correctly by using an arp
command with the -a option.
arp -a
This command shows all arp entries for the server or workstation. See your
system administrator guide if you need additional help with the arp command.
4. After the above arp command is entered correctly, launch a Telnet client to the
assigned IP address. Then, continue with Initial SCPS login in this chapter.
To configure the SCPS using the serial CLI:
1. By factory default, port 1 of the SCPS is configured for the serial CLI. To
access the serial CLI, attach a compatible device to port 1. The compatible
device types are: ASCII, VT52, VT100, VT102, VT220, VT320, IBM3151,
IBM5250 and WYSE50.
Chapter 8 lists the required cables and adaptors. You may also use any terminal
emulation program that is available on your system.
2. Configure your terminal or terminal emulation program as follows.
Baud rate 9600
Bits per character 8

Stop bits 1
Flow control None
3. Press the
Return or Enter key until a prompt appears, requesting your
username. If you do not receive a > prompt after pressing the key five times,
check your cable and serial settings to be sure that they are correct.
4. Proceed to Initial SCPS login in this chapter.
After you complete the SCPS configuration, you may reconfigure the CLI on
another port or disable it completely and use port 1 with an attached device. For
more information, see Connecting to devices from the serial CLI port in Chapter 4.
Initial SCPS login
The SCPS ships with a single user defined in its user database. The first time you
connect to the SCPS via Telnet or serial CLI, you are prompted for a username.
To log in to the SCPS for the first time:
1. At the Username prompt, type Admin. There is no password for the Admin
user. At the password prompt, press Return.
2. Once authentication completes, the SCPS prompts for any missing
configuration values that are required for operation.
If you already provided the IP address and subnet mask, you will not be
prompted for those values again.
If you have not already provided the IP address and subnet mask, you will be
prompted for them. Enter the SCPS IP address and subnet mask using standard
dot notation.
3. You are prompted for a new Admin password. Passwords are case sensitive and
must contain 3-16 alphanumeric characters. You must enter the new password
twice to confirm that you entered it correctly.
After you have provided the required configuration information, the following
message appears while the SCPS stores the values in its configuration database.
Configuration is being stored. Please wait.
IP Address is 192.168.0.5 with subnet mask 255.255.255.0 has
been set
New Admin password has been set
>
You have now completed the initial login, and you may enter additional commands
at the CLI prompt (>). To configure other SCPS ports, see Configuring Serial Port
Settings in Chapter 4.

3.4 Reinitializing the SCPS
Reinitializing the SCPS removes configured information. This may be useful when
reinstalling the SCPS at another location in your network.
The SCPS stores configuration information in FLASH databases. During reinitialization,
the FLASH erase has two phases. The first phase erases the SCPS configuration
database, which contains all nonvolatile data except the IP address. The second phase
erases the IP address and restores the SCPS to its factory default settings.
To reinitialize the SCPS:
1. Locate the recessed INIT button on the front of the SCPS. You will need a non-
conductive, non-metallic tool that fits inside the recess.
2. Insert the tool in the recess, then depress and hold the button. The ONLINE
LED will blink, indicating an SCPS initialization has been requested. You have
approximately seven seconds to release the button before any action is taken.
After seven seconds, the ONLINE LED will blink more rapidly to confirm that
the SCPS configuration database has been erased. Continuing to hold the INIT
button for a few more seconds will erase the IP address as well. The ONLINE
LED will blink faster to confirm the deletion.
If any portion of FLASH is erased, the SCPS reboots when the INIT button is released.

4. Operations
4.1 Overview
The SCPS and its ports can be easily configured and managed to meet your
requirements for device connection, user authentication, access control, device
session information display and SNMP compliance for use with third-party network
management products. Support for SSH (Secure Shell) access via third-party clients
is also provided.
4.2 Configuring Serial Port Settings
By default, the SCPS ports are configured with the following settings.
Baud rate 9600
Bits per character 8
Parity None
Stop bits 1
Flow control None
Time-out 15 minutes
CLI access character ^D
To change serial port settings:
Issue a Port Set command. You may specify settings for one or all ports.
PORT [<port>|ALL] SET [BAUD=<baud_rate>] [SIZE=<size>]
[PARITY=<parity>] [STOP=<stop_bits>] [FLOW=<flow_ctrl>]
[TIMEOUT=<time-out>] [SOCKET=<socket>] [CHAR=^<cli_char>]
[TOGGLE=NONE|DTR]
For more information, see Port Set command in Chapter 6.
To display serial port settings:
Issue a Show Port command.
SHOW PORT [<port>|ALL]
The display includes configuration information plus transmit, receive and error
counts. When you request information about a single port and a user is currently
accessing that port, the display also includes the username, access rights and other
information about the current session. For more information, see Show Port
command in Chapter 6.

4.3 Connecting to Serial Devices
The SCPS offers several methods for connecting to attached serial devices: Telnet,
serial CLI, PPP and SSH.
The SCPS monitors data traffic when you are connected to an attached serial device.
You may specify a time-out value with the Server CLI command. You may also specify
a time-out value for each port with the Port Set command. When no data is received or
transmitted for the configured number of minutes, the connection is terminated.
The following time-out values are used:
• For a Telnet session, the Server CLI time-out value is used.
• For a serial port session, if the port’s configured time-out value is Ø, the Server
CLI time-out value is used, even if it is also Ø.
• For a serial port session, if the port’s configured time-out value is non-Ø, that
value is used.
Connecting to devices using Telnet
Each SCPS serial port has a unique Telnet socket number that provides a connection
to the attached serial device.
To connect to a device using Telnet:
Type telnet, followed by the SCPS IP address and the port’s socket number, which
is 3000 plus the port number.
For example, the following Telnet command connects to the serial device attached
to port 7 of the SCPS.
telnet 192.168.0.5 3007
If an authentication method other than None has been configured for the SCPS, you
will be prompted for a username and password. Once authentication completes,
your connection is confirmed. When you successfully connect to the serial device,
you will see a display similar to the following.
Username: Myname
Password: ******
Authentication Complete
Connected to Port: 7 9600,8,N,1,XON/XOFF
Data entered at the Telnet client is written to the attached serial device. Any data
received by the SCPS from the serial device is output to your Telnet client.

Connecting to devices from the serial CLI port
By factory default, port 1 of the SCPS is configured with the serial CLI, which
prohibits the use of port 1 with an attached serial device. You can configure a
different port with the serial CLI, but only one port may be configured as the serial
CLI port at one time. For example, if you attempt to enable the CLI interface on port
n, and it is already active on port p, then the CLI will automatically be disabled on
port p.
You may connect to one serial device at a time through the serial CLI port, using a
local terminal or a local PC using a terminal emulation program. If you connect an
external modem to the serial CLI port, you can also access devices through a remote
terminal or PC that can dial into the SCPS external modem. For information about
modem connections, see Configuring and using dial-in connections in this chapter
and Server CLI command in Chapter 6.
To configure a port for the serial CLI:
1. Issue a Server CLI command, using the Port parameter to specify the CLI port
and the Type parameter to specify the terminal type.
SERVER CLI PORT=<port> TYPE=<type>
2. To disable the CLI that was previously configured on a port, issue a Server CLI
command, indicating Type=Off.
For more information, see Server CLI command in Chapter 6.
To display CLI port information:
Issue a Show Server CLI command.
SHOW SERVER CLI
The display includes the CLI port number and terminal type, plus the CLI access
character. For more information, see Show Server CLI command in Chapter 6.
To connect to a device from the serial CLI port:
1. Issue a Server CLI command, using the Connect parameter to enable the use of
the Connect command from the serial CLI port.
SERVER CLI CONNECT=ON
2. Issue a Connect command to the desired port.
CONNECT <port>
