Installing a Power Supply Unit
Warning All AC and DC versions of this equipment must be earthed.
You cannot install an AC PSU and a DC PSU in the same switch chassis.
If you remove a PSU or FOM from the switch, ensure that you replace it to
prevent dust and debris from entering the chassis and to maintain proper airflow
in the switch.

Removable Power Supply and Fan
Installing a power supply unit or fan-only module
Before you begin:
■
Read the safety information for the switch.
Safety information is available in the Installation and Safety Guide that is on
the CD-ROM for the switch. Or you can download this document from
www.alliedtelesyn.co.nz/documentation.
■
Gather necessary tools and equipment.
You may need a Phillips #2 screwdriver to adjust the retaining screws on a
PSU or 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.
■
Verify the package contents if you have not already done so.
See “Package Contents” on page 4. Contact your authorised distributor or
reseller if items are damaged or missing.
1.
Unpack the power supply unit.
Caution Follow correct anti-static procedures when installing either a PSU
or FOM. Failure to do so could damage the PSU, FOM, or switch. If you are
unsure about correct procedures, contact your authorised distributor or
reseller.
While observing Electro Static Discharge (ESD) precautions, remove the
PSU or FOM from its packing material in an anti-static environment.
2.
Disconnect the power supply from the power supply unit.
Warning Disconnect the power cord before removing the PSU.
For AC models, turn off the main power supply to the PSU and disconnect
the power cord.
For DC models, push the Run/Standby control and release it to the Off
position using a small diameter pin. When the Run/Standby control is not
depressed, it is off. Disconnect the supply cable wires from the circuit
breaker.
3.
For AC models only, install the power cord retaining clip.
There is one retaining clip for the AC power inlet on the PSU.

Installation Guide
4.
Remove the current power supply unit or fan-only module from
the switch.
Loosen the two captive Phillips screws on the PSU or FOM until the screws
are fully loosened (see figure below).

PSU2
Slowly and carefully slide the PSU or FOM out of the bay. Support the
device from underneath as you remove it to prevent it from falling.
When you have one PSU for AT-9924T and AT-9924SP models, it must be
installed in bay 2 to optimise cooling.
Caution Cover empty bays because dust and debris could overheat or
damage the PSU and switch.
5.
Insert another power supply unit.
Caution Keep the PSU or FOM in straight alignment and insert it slowly.
Forcing a misaligned PSU or FOM is likely to damage both the chassis and
PSU or FOM.
Slowly and carefully slide the PSU or FOM into the power supply bay.
Firmly press the PSU or FOM until the faceplate engages, or nearly engages,
the chassis.
6.
Secure the power supply unit.
Tighten the two captive Phillips screws on the faceplate of the PSU or FOM
(see figure in Step 4).

Removable Power Supply and Fan
Applying Power to the Power Supply Unit
For an AC power supply unit
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.
For a DC power supply unit
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 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).
Installation Guide
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.
Checking LEDs
LEDs indicate the operational status on the faceplate of each PSU and on the
front panel of the switch.
After you have inserted the PSU and powered on the switch, check the LEDs for
correct operation by using the following tables.
Table 1: LEDs on the power supply unit and fan-only module
LED
State
Description
Fault
Red
The temperature of the PSU has exceeded the limit of
75º C (167 º F), or the FOM has failed.

Green
A PSU is installed in the switch and is receiving power.
FOMs do not have this LED.
Table 2: PSU LEDs on the switch

Description
PSU 1
Green
PSU 1 is installed and supplying power to the switch.
The voltage output is within specification.
Red
PSU 1 is installed in the switch and has exceeded its
recommended temperature threshold of 75º C
(167º F), or the fan has failed.
A FOM is installed in the switch and has failed.
The bay is empty.
Off
A FOM is installed and operating at an acceptable
speed.
For AT-9924T and AT-9924SP models, this LED is
always off because a FOM is not required.

Troubleshooting
If the PSU does not function as expected:
■
check that all cable connections are correct and secure.
■
check that the standby switch has been pressed and is in the On position
(DC models).
■
check that the PSU is receiving the correct AC voltage (AC models).
■
if LEDs indicate a PSU fault, replace the PSU or have your authorised
distributor or reseller service it.
Additional troubleshooting information is in the Hardware Reference for the
switch.
