Package Contents
Depending on the model, switches are shipped with a single supply unit (PSU),
either AC or DC. Some models also have fan-only modules (FOM), chassis fan
modules, or blanking plates.

blanking plates, but no PSUs.
The following items are included with each factory-installed PSU. Contact your
authorised Allied Telesis distributor or reseller if any are damaged or missing.
■one AC power cord (AC models)
■one power cord retaining clip (AC models)

Installing a Power Supply Unit or Fan
Use these instructions to install PSUs, chassis fan modules and FOMs.
■Do not combine PWR01 and PWR02 PSUs in the same switch.
■Do not combine AC and DC PSUs in the same switch.
Before you begin
■Read the safety information for the switch.
Safety information is in the x900 Series Switch and SwitchBlade®x908
Installation and Safety Guide. You can download this document from
www.alliedtelesis.com/support/software.
■Gather necessary tools and equipment.
You will need an appropriate flat-bladed or Phillips (#1) screwdriver to tighten
or loosen the captive screws.
■Verify the package contents if you have not already done so.
See “Package Contents” on page 5. Contact your authorised Allied Telesis
distributor or reseller if items are damaged or missing.
■Remove the unit from its packing material in an anti-static environment.
Caution Follow correct anti-static procedures. Failure to do so could
damage the PSU, fan, or switch. If you are unsure about correct procedures,
contact your authorised Allied Telesis distributor or reseller.
Caution When adding or replacing power supplies, keep your hands and
fingers out of the power supply bays. After installing a PWR05 power supply,
use a screwdriver to tighten the captive screw such that a screwdriver will be
required to remove the PSU at a later date.
Installation Guide

Installing a PWR01, PWR02, or FAN01
1. If you are replacing a PSU, disconnect the power cord from the currently
installed PSU before removing it.
For AC PSUs, turn off the main power source to the PSU and disconnect
the power cord.
For DC PSUs, push the Run/Standby control and release it to the Off
position. When the Run/Standby control is not depressed, it is off.
Disconnect the supply cable wires from the circuit breaker.
2. Remove the current PSU, fan, or blanking plate from the switch.
Loosen the captive screws until fully loosened.
If a unit is already in the bay, slide it out slowly and carefully. Support the
unit from underneath as you remove it to prevent it from falling.
Cover empty bays with a blanking plate because dust and debris could
overheat or damage the unit and switch.
3. Insert the new PSU or fan unit, and carefully slide it into the bay.
Insert it slowly, being sure to keep it straight. Firmly press the unit until the
faceplate engages, or nearly engages, the chassis. Forcing a misaligned unit
into the bay is likely to damage both the unit and chassis.
Note that when you have only one PSU installed in the AT-9924T and
AT-9924SP switches, it must be installed in bay 2 to optimise cooling.
4. Secure the unit in the switch by tightening the captive screws on the
faceplate.

Installing a PWR05 or FAN03
1. If you are replacing a PSU, turn off the main power source to the PSU and
disconnect the power cord before removing it.
The DC earthing connection is not necessary for the SwitchBlade x908 when
using AC PSUs because the chassis is grounded through the power cords.
2. Remove the current PSU, fan module, or blanking plate from the switch.
Using a screwdriver, loosen the captive screw(s) until fully loosened.
If a unit is already in the bay, slide it out slowly and carefully. Support the
unit from underneath as you remove it to prevent it from falling.
Avoid the spinning blades on chassis fan modules. Contact may cause
personal injury or damage the unit.
Cover empty bays because dust and debris could overheat or damage the
unit and switch. Do not operate the switch for extended periods without
functioning chassis fan modules. Doing so will cause the switch to overheat
and shut down, and may damage the switch.
3. Insert the new PSU or chassis fan module, and carefully slide it into the bay.
If you are installing a PSU, unlock the latch on the PSU first by loosening the
captive screw.
Insert the PSU or fan module slowly, being sure to keep it straight. Firmly
press the unit until the faceplate engages, or nearly engages, the chassis.
Forcing a misaligned unit into the bay may damage both the unit and chassis.
4. Secure the unit in the switch by tightening the captive screw(s) on the
faceplate. On the PWR05, use a screwdriver to tighten the captive screw
such that a screwdriver will be required to remove the PSU at a later date.

Connecting an AC power supply
Follow these instructions to connect an AT-PWR01, AT-PWR02, or AT-PWR05
AC PSU to an AC power supply:
Warning The AT-PWR01 AC PSU has a fuse rating of 250V, 5A for FH101 and
FH102.
Warning The AT-PWR01 AC PSU has double pole/neutral fusing. Electric
shock is possible since there are dual primary fuses, one on the phase circuit and
one on the neutral circuit. If the neutral opens, the phase may still be live.
Warning For SwitchBlade x908 AC models the grounding stud on the rear of
the unit is for supplemental grounding only. The system must be supplied by a
grounded 3 wire AC source through the power supply cord.
Connecting a PWR01 or PWR02
1. Plug the supplied AC power cord into the power inlet on the PSU and
attach the retaining clip.
2. Connect the power cord to the main power source.
3. The PSU LED on the front panel of the switch lights green. If the LED does
not light, refer to the Hardware Reference for troubleshooting information.
Connecting a PWR05
1. Form a loop in the supplied AC power cord at the PSU end and clip the
ferrite core over the looped cord, as shown in the following illustration.
This keeps the ferrite core in its correct position, close to the PSU.
2. Plug the AC power cord into the power inlet on the PSU.
