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 7 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. Captive screw Captive screw PSU Switch Removable Power Supply and Fan 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. Captive screw PSU baysPSU Captive screw Chassis fan Service access panels 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. Looped power cord Ferrite core 2. Plug the AC power cord into the power inlet on the PSU. Removable Power Supply and Fan 3. Connect the power cord to the main power source. 4. Check that the Run/Standby switch is set to the Ru...
