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.

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.

Installation Guide  
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.
