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.
■The AT-8948, AT-9924Ts, x900-24XT, x900-24XT-N, and x900-24XS
switches have a PSU and a FOM installed.
■The x900-48FE, x900-48FS, AT-9924T, and AT-9924SP switches have a PSU
and a blanking plate installed.
■The SwitchBlade®x908 is shipped with dual chassis fan modules and
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.

Installing a Power Supply Unit or Fan
Use these instructions to install PSUs, chassis fan modules and FOMs.
■Do not combine AC and DC PSUs in the same switch.
■Do not combine PWR01 and PWR02 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.
Youwillneedanappropriateflat-bladedorPhillips(#1)screwdrivertotighten
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 thata screwdriver will be
required to remove the PSU at a later date.

Installation Guide

Installing a PWR01, PWR02, or FAN01
1. If there is a PSU, fan or blanking plate in the bay you wish to install the unit,
first remove the old unit, following the steps described in section
“Removing a Power Supply Unit or Fan” on page 19.
2. 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.
3. Secure the unit in the switch by tightening the captive screws on the
faceplate.

Installing a PWR05 or FAN03
1. If there is a PSU, fan or blanking plate in the bay you wish to install the unit,
first remove the old unit, following the steps described in section
“Removing a Power Supply Unit or Fan” on page 19.
2. 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.
3. 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 250VAC, 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 When x900-24 units are connected with VCS stacking cables (XEM-
STK-CBL) ensure that all the PSUs are appropriately grounded. This is to avoid
large circulating ground currents that could damage the stacking cables. To
achieve this ensure that:
■AT-PWR01 AC is grounded by the 3-pin AC power connector
■All grounding points are at the same ground level. That is, all power
connectors share a common power distribution unit.
Warning For SwitchBlade x908 units with AC PSUs, the grounding stud on the
rear of the device is provided for situations where an additional ground is
required. The device must be powered from a grounded 3 wire AC source via the
AC power cable and connector.
Warning When SwitchBlade x908 units are connected with VCS stacking
cables (either HS-STK-CBL or XEM-STK-CBL), each individual stack member
chassis must be additionally grounded by using the rear grounding-terminal on
each device. In order to avoid large circulating ground currents, thewires of each
grounding cable must be 18 AWG (0.8mm2) or thicker.
