Selecting a Site
The switch can be installed in a standard 19 inch rack, on a level surface such as
a desktop or bench, or against a wall using the optional wall-mount kit. When
installing the switch, choose a site that:
■allows adequate airflow around the switch and its vents.
■is free of dust and moisture.
■will maintain an ambient temperature range of 0 to 50º C (32 to 122º F) and
a humidity range of 5 to 95% non-condensing.
■has a reliable and earthed (grounded) power supply, preferably dedicated
and filtered.
■does not expose cabling to sources of electrical noise, such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■allows easy access to the switch’s power and cable connections.
■will allow all related network devices to be connected to the switch
without exceeding maximum cable length limitations as specified in the
AT-8900 Series Hardware Reference.
■will ensure that when a switch is mounted in a rack, it is mounted evenly
to prevent uneven mechanical loading of the rack.

Installing the Switch
This equipment must be earthed.
Follow these steps to install the switch:
1. Read the safety information
For safety information, see the Safety and Statutory Information booklet. A
copy of this booklet is supplied with each switch, and can also be found on
the Documentation and Tools CD-ROM or at
http:// www.alliedtelesyn.co.nz/support/at8900.
2. Gather the tools and equipment you will need
If installing a switch with a DC PSU, you will need an appropriate DC
power source, DC supply cable, ring connectors, and a crimp tool.
3. Choose a suitable site for the switch
Either a 19 inch rack, a flat bench, or a wall.
4. Unpack the switch
Verify the package contents. If any items are damaged or missing, contact
your sales representative.
5. Place the switch in its operating location
See the previous “Selecting a Site” section for guidelines on choosing a
suitable location.
To install the switch using the 19 inch rack-mount kit:
• Ensure the rack has sufficient space for the switch and its associated
cables.
• Remove the rubber feet from the switch.
• Screw the brackets to the sides of the switch using the supplied M4
screws (see Figure 1).
• Fit the adjustable bracket extension onto the rear bracket but do not
fully tighten the nuts. You may need to adjust the position of the
extension bracket to correctly fit the switch into the rack (see Figure 1).
• Mount the switch in the rack using appropriate rack mounting screws
(not supplied).

To install the switch using the wall-mount kit:
• Ensure that there is sufficient space on the wall for the switch and its
associated cables.
Note that the wall-mount kit is designed to hold the switch against the
wall with the front and back of the switch vertical.
• Remove the rubber feet from the switch.
• Screw the brackets to the sides of the switch using the supplied M4
screws (see Figure 2).
• Locate the position on the wall where the switch will be mounted.
• Locate and mark the position on the wall where the top wall-mount
brackets will be fixed.
The top wall-mount brackets are fixed to the wall through the wall
anchor slot (see Figure 2).
Make sure that the positions you have marked on the wall are the
correct distance apart and are horizontal.
• Fix two wall anchors in the wall, one for each bracket.
• Hang the switch from these anchors.
Fix additional wall anchors through the bottom wall-mount brackets, 2
per bracket.
• Ensure that all wall anchors are tightened sufficiently to secure the
switch firmly against the wall.

6. Apply power to the PSU
For AC Models:
Read the AT-8900 Series Statutory and Safety Information booklet before
connecting a PSU to an AC power source.
Plug the provided AC power cord into the AC power inlet on the rear
panel of the PSU and connect the PSU to the mains power supply.
Important information for service personnel only:
• CAUTION: double pole/neutral fusing
• The ratings of fuses FH101 and FH102 is 250 V, 5 A
For DC models:
Read the AT-8900 Series Statutory and Safety Information booklet before
connecting a PSU to a DC power source.
Only trained and qualified personnel should connect a DC power supply.
For centralized DC power connection, the switch should be installed only in
Restricted Access Areas (Dedicated Equipment Rooms, Equipment Closets, or
the like) in accordance with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NAPA 70.
DC supply cable specifications:
• Three core cable is required
• Minimum core size: 3.3 mm2(12 AWG) high strand count copper wire
• Minimum cable rating: 600 V, 90 degrees Celsius
DC power supply specifications:
• 40 to 60 V, 48 V nominal
• Supports either positive grounded or negative grounded operation
Circuit protection:
• 10 Amp certified/Listed circuit breaker is required for branch circuit
protection
To connect the DC supply:
Ensure that the supply cable is not live.
1. Remove the transparent protective terminal cover.
2. Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare
conductor. Terminate with JST FN5.5-5 or equivalent, using a crimp
tool.

3. Connect the ground wire to the ground terminal. Terminals can be
identified by the diagram on the switch’s rear panel. Tighten the
terminal to between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
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).
Check that the PSU terminals are wired to the correct polarity. A PSU will be
damaged if incorrectly connected.
5. Ensure there are no exposed cable strands.
6. Replace the transparent plastic terminal cover.
The transparent plastic terminal cover must be replaced.
7. Secure the supply cable (to the rack framework or similar object) so that
the connections are isolated from any force applied to the cable.
8. Ensure the circuit breaker (for the supply circuit) and the Run/Standby
switch (on the switch) are in the OFF position.
9. Connect the supply cable wires to the circuit breaker.
10. Switch the power switch to the ON position.
7. Check that at least one of the PSU LEDs on the switch’s front panel is lit green
If the LEDs fail to light, refer to the AT-8900 Series Hardware Reference for
troubleshooting information.
8. Connect the data cables
Make sure that each cable connection is secure.
The switch will now perform basic Layer 2 switching functions.

Configuring the Switch
Some configuration is necessary to enable the switch’s advanced switching
capabilities. This is achieved via the Command Line Interface (CLI).
Using the CLI to configure a switch
1. Connect a terminal or PC to RJ-45 (ASYN0)
Using the supplied RJ-45 straight-through cable, connect your terminal or
PC to the RS-232 Terminal Port on the switch’s front panel.
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
•Stopbits:1
• Flow control: 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 log in prompt appears. If the log in prompt
doesn’t appear, press [Enter] two or three times.
When the switch boots for the first time it automatically creates an account
with manager privileges. The account has the log in name “manager” and
the password is “friend”.
At the log in prompt, enter the log in name and password.
Login: manager
Password: friend
The switch’s command prompt appears. Now configure the switch using
the command line interface.
Change the password as soon as possible. Leaving the manager account with
the default password is a serious security risk. Remember the new password as
there is no way to retrieve it if it is lost.
Use the following command to change the account password:
set password
