1 PRODUCT OVERVIEW
1.1 Features and Benefits
The Vertiv™Avocent® MergePoint Unity™ KVM over IP and serial console switch system for Dell combines
analog and digital technology to provide flexible, centralized control of data center servers and virtual
media, and to facilitate the OA&M (operations, activation and maintenance) of remote branch offices
where trained operators may be unavailable. The IP-based switch gives you flexible target device
management control and secure remote access from anywhere at anytime.
The switch provides enterprise customers with the following features and options:
•significant reduction of cable volume
•keyboard, video and mouse (KVM) capabilites, configurable for analog (local) or digital
(remote) connectivity
•true serial capability through Secure Shell (SSH) and Telnet

•dual stack IPv4 (DHCP) and IPv6 (DHCPv6 and auto configuration) for simultaneous access
•smart card capability
•accessibility to target devices across 10/100 or 1000BaseT (some models) LAN port(s)
•supports V.34, V.90 or V.92-compatible modems that may be used to access the switch when
an Ethernet connection is not available
1.1.1 Reduce cable bulk
With server densities continually increasing, cable bulk remains a major concern for network
administrators. The switches significantly reduce KVM cable volume in the rack by utilizing the innovative
IQ module and single, industry-standard Unshielded Twisted Pair (UTP) cabling. This allows a higher
server density while providing greater airflow and cooling capacity.
1.1.2 KVMswitching capabilities
The switch supports IQmodules, which are powered directly from the target device and provides Keep
Alive functionality when the switch is not powered. The following IQ modules are supported:DSRIQ-PS2,
DSRIQ-USB, DSRIQ-VMC, DSRIQ-SUN, DSAVIQ-USB2 DSAVIQ-PS2M and MPUIQ-VMC modules. The
DSAVIQ-USB2, DSAVIQ-PS2M DSRIQ-VMC and MPUIQ-VMC modules are virtual media-capable. The
DSRIQ-VMC and MPUIQ-VMC modules are also smart card-capable.
Vertiv™ | Vertiv™ Avocent® MergePoint Unity™ Switch for Dell® Installer/User Guide | 1

1.1.3 True serial capabilities
The switch supports the MPUIQ-SRL module, which provides true serial capabilities through Telnet. You
can launch an SSHsession or launch a serial viewer from the on-board web interface (OBWI) to connect
the switch's attached target devices that have an MPUIQ-SRL module.
1.1.4 Local and remote user interfaces
You can use the local user interface (local UI) by connecting directly to the local port to manage the
MergePoint Unity switch. You can also use the remote OBWI to manage your switch system. The OBWI is
web-browser based and is launched directly from the switch, and any servers connected to the switch are
automatically detected. The two user interfaces share a similar look and feel for an optimal user
experience.
1.1.5 Control of virtual media and smart card-capable appliances
The switches allow you to view, move or copy data located on virtual media to and from any target device.
Manage remote systems more efficiently by allowing operating system installation, operating system
recovery, hard drive recovery or duplication, BIOS updating and target device backup.
The switches allow you to use smart cards in conjunction with your switch system. Smart cards are
pocket-sized cards that store and process information. Smart cards such as the Common Access Card
(CAC) can be used to store identification and authentication to enable access to computers, networks
and secure rooms or buildings.
Virtual media and smart card readers can be connected directly to the switch using USB ports located on
the switch. In addition, virtual media and smart card readers may be connected to any remote workstation
that is running the remote OBWI or DSView™ management software and is connected to the switch using
an Ethernet connection.
NOTE: The switch supports versions prior to and including DSView 4 management software.
NOTE: To open a virtual media session with a target device, you must first connect the target device to
a switch using a virtual media capable DSAVIQ-USB2, DSRIQ-PS/2M DSRIQ-VMC or MPUIQ-VMC
module. For a smart card, you must first connect the target device to a switch using a smart card-
capable DSRIQ-VMC or MPUIQ-VMC module.
1.1.6 Access the switch via a standard TCP/IP network
The switches provide agentless remote control and access. No special software or drivers are required on
the attached servers or client.
NOTE: The client connects to the server hosting the DSView management software using an Internet
browser.
Users access the switch and all attached systems via Ethernet or using a V.34, V.90 or V.92 modem from a
client. The clients can be located anywhere a valid network connection exists.
Vertiv™ | Vertiv™ Avocent® MergePoint Unity™ Switch for Dell® Installer/User Guide | 2

1.1.7 FIPS cryptographic module
The switch follows the guidelines set forth by the FIPS 140-2 program. The FIPS mode of operation can be
enabled or disabled via the OBWI or local port and is executed after a reboot. When the FIPS module is
enabled, a reboot of the switch requires approximately two additional minutes to complete a FIPS mode
integrity check. Also, when FIPS is enabled, if the keyboard, mouse or video encryption is set to 128-bit SSL
(ARCFOUR) or DES, the encryption level is automatically changed to the encryption level AES.
NOTE: The FIPS mode of operation is initially disabled and must be enabled to operate. The Setup port
factory default setting will automatically disable the FIPS module. The FIPSmode cannot be changed
via the DSView software plug-in.
The switch uses an embedded cryptographic module that is based on the FIPS validated cryptographic
module(s) (certificate numbers 1747 and 1279) running on a Linux PPC platform.
1.1.8 DSView™ management software plug-in
The DSView software may be used with the switch to allow IT administrators to remotely access, monitor
and control target devices on multiple platforms through a single, web-based user interface. For more
information, see the DSView Software Plug-In for MergePoint Unity switch for Dell Technical Bulletin.

2 INSTALLATION
2.1 MergePoint Unity Switch for Dell Connectivity
The MergePoint Unity switching system for Dell transmits KVM and serial information between operators
and target devices attached to the switch over a network using either an Ethernet or modem connection.
The switch uses TCP/IP for communication over Ethernet. Although 10BaseT Ethernet may be used,
Vertiv™ recommends a dedicated, switched 100BaseT or 1000BaseT network for switches that support it.
The switch uses the Point-to-Point Protocol (PPP) for communication over a V.34, V.90 or V.92 modem.
You can perform KVM and serial switching tasks by using the OBWI or the DSView software. For more
information on the DSView software, visit http://www.VertivCo.com or see the DSView Installer/User Guide.

6. If using the power supply, connect the MPUIQ-SRL module power supply to an appropriate AC
wall outlet. Turn on your serial device.
2.4 Cascading Switches
You can cascade up to two levels of switches, enabling users to connect to up to 1024 servers. In a
cascaded system, each target port on the main switch will connect to the ACI port on each cascaded
switch. Each cascaded switch can then be connected to a server with an IQ module.
To cascade multiple switches:
1. Attach one end of a CAT 5 cable to a target port on the switch.
2. Connect the other end of the CAT 5 cable to the ACI port on the back of your cascaded switch.
3. Connect the devices to your cascaded switch.
4. Repeat these steps for all the cascaded switches you wish to attach to your system.
NOTE: The system will automatically “merge” the two switches. All servers connected to the cascaded
switch will display on the main switch server list in the local UI.
Vertiv™ | Vertiv™ Avocent® MergePoint Unity™ Switch for Dell® Installer/User Guide | 9

NOTE: The MergePoint Unity switch for Dell supports one cascaded switch per target port of the main
switch. You cannot attach more switches to the cascaded switches.
NOTE: Local port cascading is not supported on the MergePoint Unity switch.
2.5 Configuring the MergePoint Unity Switch for Dell
Once all physical connections have been made, you will need to configure the switch for use in the overall
switching system. This can be accomplished in two ways.
To configure the switch using the DSView software:
See the DSView Installer/User Guide for detailed instructions.
To configure the switch using the local UI:
See Network Settings on page 23 for detailed instructions on using the local UI to configure initial network
setup.
2.5.1 Setting up the built-in web server
You can access the switch via an embedded web server that handles most day-to-day switching tasks.
Before using the web server to access the switch, first specify an IP address through the local port on the
back panel of the switch or local UI. See Local and Remote Configuration on page 15 for detailed
instructions on using the user interface for switching.
2.5.2 Connecting to the OBWI through a firewall
For switch installations that use the OBWI for access, four ports must be opened in a firewall if outside
access is desired.

For information on launching the OBWI, see OBWI on page 16.
2.6 Verifying the Connections
2.6.1 Front and rear panel Ethernet connection LEDs
On 16-port and 32-port models of the switch, the front and rear panels feature two LEDs indicating the
Ethernet LAN1 connection status and two LEDs indicating the Ethernet LAN2 connection status. On the
4-port and 8-port switches, all LEDs are on the rear panel.
•The green LEDs illuminate when a valid connection to the network is established and blink
when there is activity on the port.
•The bi-color LEDs may illuminate either green or amber.
•They illuminate green when the communication speed is 1000M.
•They illuminate amber when the communication speed is 100M.
•They are not illuminated when the communication speed is 10M.
Vertiv™ | Vertiv™ Avocent® MergePoint Unity™ Switch for Dell® Installer/User Guide | 11

2.6.2 Front panel status LEDs
The front panel of switches (16-port and 32-port models only) have a bi-color general status LED that may
illuminate green or amber.
•The LED illuminates green when the switch is turned on and operating normally.
•The LED blinks green when the switch is booting.
•The LED illuminates amber if a fault condition occurs, such as power supply failure (for
switches equipped with dual power supplies), elevated ambient temperature or fan failure. The
LED will continue to illuminate amber as long as the failure persists.
•The LED blinks between green and amber when the switch is Flash downloading.
2.6.3 Rear panel power status LEDs
The rear panel of 16-port and 32-port switches feature one power status LED for single power switches
and two power status LEDs for dual power switches. On the 4-port and 8-port switches, all LED status
indicators are on the rear panel. The LED(s) illuminate green when the switch is turned on and operating
normally.
•The LED is off if the power supply does not have power or has failed.
•The LED illuminates when the unit is ready.
•The LED blinks when the switch is booting or an upgrade is in progress.
•The LED blinks "SOS" if a fault condition occurs, such as power supply failure (for switches
equipped with dual power supplies), elevated ambient temperature or fan failure. The LED will
continue to illuminate amber as long as the failure persists.
2.6.4 IQ and DSRIQ-SRL modules
Typically, IQ modules feature two green LEDs: a Power LED and a Status LED.
•The Power LED indicates that the attached module is turned on.
•The Status LED indicates that a valid selection has been made to the switch.
The DSRIQ-SRL module prevents a serial break from the attached device if the module loses power.
However, a user can generate a serial break with the attached device by pressing Alt+B after accessing
the Terminal Applications menu.
2.7 Adjusting Mouse Settings on Target Devices
Before a computer connected to the switch can be used for remote user control, you must either enable
Vertiv Mouse Sync (see ) or set the target mouse speed and turn off acceleration. For machines running
Microsoft®Windows®(Windows NT®, 2000, XP, Server 2003), use the default PS/2 mouse driver.
To ensure that the local mouse movement and remote cursor display remain in sync, mouse acceleration
must be set to “none” for all user accounts accessing a remote system through a KVM switch. Mouse
acceleration must also be set to “none” on every remote system. Special cursors should not be used and
Vertiv™ | Vertiv™ Avocent® MergePoint Unity™ Switch for Dell® Installer/User Guide | 12

cursor visibility options, such as pointer trails, Ctrl key cursor location animations, cursor shadowing and
cursor hiding, should also be turned off.
For more information about setting mouse movement and cursor features for use with Vertiv™ hardware
products and DSView management software, please visit http://www.VertivCo.com and consult the Mouse
and Pointer Settings guide.
NOTE: If you are not able to disable mouse acceleration from within a Windows operating system, or if
you do not wish to adjust the settings of all your target devices, newer versions of the DSView
software include the Tools Single Cursor Mode command available in the Video Viewer window. This
command places the Video Viewer window into an “invisible mouse” mode which allows you to
manually toggle control between the mouse pointer on the target system being viewed and the mouse
pointer on the client server running DSView software.
