For your well-being and that of the equipment, read the safety information in
this document. You can also download this document from the
Documentation and Tools CD-ROM or from www.alliedtelesyn.com
■Verify the package contents if you have not already done so.
See “Package Contents” on page 4. If any items are damaged or missing,
contact your authorised distributor or reseller.
■Gather necessary tools and equipment.
You need a Phillips #2 screwdriver to adjust the retaining screws on the
power supply unit (PSU) or fan-only module (FOM).
To install a DC version of the PSU, you need an appropriate DC power
source, DC supply cable, ring connectors, and a crimp tool.
■Choose a suitable operating location.
Follow the guidelines described in “Selecting a Site” on page 5 to choose a
suitable location.
■Decide whether two people are needed to mount the switch into the rack
and tighten the screws (step 7).
■If you have an optional expansion module for the AT-9900s Series switch,
install it in the switch first.
Refer to the Expansion Module Installation Guide for the AT-9900s Series Switch

screws.
10. Tighten the nuts that secure the adjustable bracket extensions to the rear
brackets.
11. Check that all screws and nuts are fully tightened.
Applying Power to the Switch
The switch has two bays in the rear. Your switch comes with one pre-installed
power supply unit (PSU). Depending on the model, the switch also has one
fan-only module (FOM) or one blanking panel over a power supply bay,
AC power supply
Important information for service personnel:
■CAUTION: double pole/neutral fusing
■the rating of fuses FH101 and FH102 is 250 V, 5 A (AT-PWR01 only)
Procedure for AC power supply
To apply power to the PSU, plug the AC power cord that is provided into the
power inlet on the faceplate of the PSU. Then connect the power cord to the
main power supply.
DC supply cable and power supply
Supply cable specifications

AT-8900, AT-9900, AT-9900s Series Switches
10
Procedure for DC power supply
Only trained and qualified personnel should connect a DC power supply.
For centralised DC power connection, the switch should be installed in
restricted access areas only (such as dedicated equipment rooms or
equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NAPA 70.
Warning Ensure that the power supply cable is not live before starting.
1. Remove the transparent protective terminal cover.
2. Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare conductor.
Terminate the wire with a nylon insulated solderless ring tongue terminal,
JST FN5.5-5 or equivalent, using a crimp tool.
3. Connect the ground wire to the ground terminal. Use the diagram on the
rear panel of the switch to identify terminals. Tighten the terminal to
between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
Caution Check that the PSU terminals are wired to the correct polarity. A
PSU will be damaged if incorrectly connected.
4. Connect the positive feed to the + (positive) terminal and the negative feed
to the - (negative) terminal. Tighten the terminals to between 2.4 and
4.0 Nm (21.3 and 35.4 lbf in).
5. Ensure there are no exposed cable strands.
6. Replace the cover. You must replace the transparent plastic terminal cover
before continuing.
7. Secure the supply cable to the rack framework or a similar object to ensure
that connections are isolated from any force applied to the cable.
8. Ensure the circuit breaker for the supply circuit and the Run/Standby
control on the PSU are off. Use a small diameter pin to press and release
the Run/Standby control so that it is not pushed in (which is the Off
position).
9. Connect the supply cable wires to the circuit breaker.
10. Turn on the PSU by pushing in the Run/Standby control with a small
diameter pin.
11. Confirm that the switch is receiving power.
Check that at least one of the PSU LEDs on the front panel of the switch is
lit green. If no LEDs light, refer to the Hardware Reference for
troubleshooting information.

Installation and Safety Guide

Connecting the Switch
Before you begin these procedures, ensure that the switch has at least one
power supply unit installed and operating. Another power supply unit or a
fan-only module must be installed in the other bay.
Using the CLI to configure a switch
1. Physically connect the terminal or PC to the ASYN0 port on the front
panel of the switch.
For AT-8948 and AT-9900 switches, use the RJ-45 straight-through cable
that is supplied.
2. Set communication parameters on your terminal or terminal emulation
program to the following:
•bitrate:9600
• data bits: 8
•parity:None
• stop bits: 1
•flowcontrol:Hardware
3. Check the power supply.
For AC models, ensure that the switch is receiving power (PWR LED is lit
green).
For DC models, ensure that the Run/Standby switch is in the On or Run
position and that the switch is receiving power (PWR LED is lit green).
4. Log in.
After the switch has booted, the login prompt is displayed. If not, 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 switch’s command prompt is displayed for you to use the CLI to
