Connect the switch to ground
The protective earth connection should be connected before proceeding with
the following power connections. The primary ground for the equipment is a
two stud grounding block (bearing the grounding symbol) located on the left
rear of the chassis, adjacent to the DC power connector.
To connect the switch to ground:
1. Using a 10AWG (5mm2cross sectional area) grounding cable (green with
yellow stripe), connect the chassis grounding stud to the office primary
ground using the two nuts with integral lock washers supplied. Tighten the
nuts with an appropriate spanner.
2. Strip an 18mm (0.75 inch) length of insulation from the grounding cable and
connect this to the grounding stud crimp terminal, using PANDUIT Uni-
Die® dieless crimping toolset. Ensure that no stranded wires protrude
from the terminal. The torque value for the chassis grounding studs is 2.57
Nm (22.8 lbf in).
Connect the DC supplies
To provide power supply resiliency, the Rapier 48w switch can receive its DC
power from either of two separate sources. Each power source should supply
48V DC (40 to 60VDC) to the switch. When the switch is powered by
centralized DC power, use UL Listed Type TC tray cables to connect the
equipment to the power sources. Each tray cable should have two conductors in
the range #14 to #12 AWG (2.0 to 2.5mm2cross sectional area), such as Belden
No. 3081A.
Each DC branch circuit should connect to the Rapier switch via a 15A
(maximum) circuit breaker or fuse that meets the requirements for branch
circuit protection. The DC supply should be fed via a circuit breaker or switch
capable of disconnecting power during servicing. The tray cable should be a UL
Listed Type TC tray cable with two conductors in the range #14 to #12 AWG
(2.0 to 2.5mm2cross sectional area), such as Belden No. 3081A.
To connect the DC supply:
1. Ensure that the DC power source is powered off during installation.
2. Strip 12mm (0.5inches) of jacket material off the tray cable and strip 7mm
(0.27inches) of insulation off each individual wire.

Installation and Safety Guide

3. Connect the A feed -48V wire to the screw terminal labelled “A -” on the
rear panel of the switch, and use a flat screwdriver to tighten the screw to
a torque of 0.5 to 0.8Nm (4.4 to 7.1lbf in). Ensure no wire strands
protrude from the terminal.
4. Connect the A feed 48V return wire to the screw terminal labelled “A +”
on the rear panel of the switch, and use a flat screwdriver to tighten the
screw to a torque of 0.5 to 0.8Nm (4.4 to 7.1lbf in). Ensure no wire
strands protrude from the terminal. Note that the DC return input
terminal must be connected as Isolated DC return (DC-I).
5. Use the same procedure to connect an additional power source, if
required, to the terminals labelled B.
6. Secure the tray cable near the rack framework using multiple cable ties to
minimize the chance of the connections being disturbed by casual contact
with wiring. Use at least four cable ties separated 10cm (4inches) apart
with the first one located within 15cm (6inches) of the terminal block.
7. Energise the DC power source to the switch.
The Fault LED should light for approximately 3 seconds as the switch runs
internal tests. If the LED remains lit, refer to the Rapier Switch Hardware
Reference for troubleshooting information.
8. Check that the Power LED on the front panel lights green.
If the LED fails to light, refer to the Rapier Switch Hardware Reference for
troubleshooting information.

Connecting Data Cables to the Switch
Once initial configuration is complete, connect the switch to the network.
Warning The Ethernet, DS3, T1, and management/asyn ports of the equipment
are suitable for connection to intra-building or unexposed wiring or cabling only.
These ports must not be metallically connected to interfaces that connect to
the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4)
and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
The management/asyn intra-building ports can only be directly connected to
equipment within the same frame, cabinet or line-up and where the equipment is
separated by a distance of 6m or less. The exception to this is when intra-
building wiring (cabling) is used for maintenance purposes only and is not
connected during normal operation.
Ethernet 10/100Mbps RJ-45 ports
Use either straight-through or cross-over twisted pair cables to connect
network devices to the 10/100MB switch ports. The switch will autonegotiate
the MDI/MDI-X polarity. Make sure that each cable connection is secure. The
switch will now perform basic Layer 2 switching functions. By default, all switch
ports are members of vlan1.
Gigabit SFP ports
SFP ports 49 and 50 support optional gigabit copper and fibre SFP (Small Form-
factor Pluggable) transceivers. For a list of supported SFPs, see the Rapier Series
Switch Hardware Reference.
Warning Do not look into the optical ports of SFP cables or transceivers.
Invisible laser radiation may be emitted from disconnected fibres or connectors.

Installation and Safety Guide
15
The SFP transceiver must be inserted the right way in the slot:
■To install an SFP in port 49 (upper), the release lever hinge must be at
the bottom.
■To install an SFP in port 50 (lower), the release lever hinge must be at
the top.
To insert an SFP transceiver, slide the transceiver into the SFP socket, and firmly
press it until it engages. To remove an SFP transceiver, first release it by gently
pulling the release lever, then pull it out of the socket. Never force a transceiver
into or out of a socket.
WAN ports
If you have installed an NSM, connect the NSM ports to the WAN. For more
information, see the Network Service Module Installation and Safety Guide and the
Network Service Module Hardware Reference.
If you have installed an AR040 or AR040-B 4-PIC NSM with PICs, connect the
PIC ports to the WAN. For more information, see the Port Interface Card
Installation and Safety Guide and the Port Interface Card Hardware Reference.

Configuring the Switch
The Rapier 48w switch can be configured with the Command Line Interface
(CLI). Before configuring the switch, you must make some basic connections
explained in the following procedure. Before starting the procedure, ensure that
the switch is installed and operating.
Using the CLI to configure the switch
1. Connect a terminal or PC to a console port.
The Rapier 48w has two identical asynchronous serial RS-232 console
ports with DB9 connectors on the front panel, asyn0 and asyn1. Using the
supplied RS-232 straight-through cable, connect your terminal or PC to
one of the console ports. For NEBS compatibility, the cable must be
shielded and grounded at both ends, especially if permanently connected.
2. Set the communication parameters.
Set the communication parameters on your terminal or terminal emulation
program to:
• Bit rate: 9600
• Data bits: 8
•Parity:None
• Stop bits: 1
• Flow control: Hardware
For information about terminal emulation, see Using Windows Terminal and
HyperTerminal in the Hardware Reference.
3. Log in at the prompt.
After the switch has booted, the login prompt appears. If the login prompt
does not appear, press the [Enter] key two or three times.
When the switch boots for the first time, it automatically creates an
account with manager privileges. The login name for the account is manager
and the password is friend.
At the login prompt, enter the login name and password as follows:
Login: manager
Password: friend
The command prompt is displayed after successful login. You can now use
the CLI to configure the switch.

Installation and Safety Guide
17
4. Change the password.
Change the password as soon as possible because a manager account with
the default password is a serious security risk. Remember the new
password because there is no way to retrieve it if you forget it.
To change the account password, use the set password command.
5. Configure the online help.
To use online help you must first configure the help file, by using the
command:
set help=<filename>.hlp
Help files have a .hlp extension. To see a list of help files loaded on your
switch, use the command:
show files=*.hlp
6. Configure the switch.
Refer to the Software Reference for more information about configuring
the software. Alternatively, if you do not know the command syntax, use
any of the following to help you:
• To display a list of help topics, use the help command.
• To display help on a specific topic, use the help <topic>command.
• To display a list of valid options, type a question mark or press the Tab
key at the end of a partial command.
• To complete a parameter after you have typed enough letters to
uniquely match the desired one, press the Tab key.
7. Save the configuration.
Save your configuration to a new file by using the command:
