Removing a power supply from the 8247-42L, 8286-41A, or 8286-42A system with the power turned off

Learn to remove a power supply from the system to replace a failing part or as part of another service procedure, with the system power turned off.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is connected to an unpainted metal surface. If not, do so now.
2. If you are removing the power supply as part of another service procedure, go to the next step. If you are servicing a failed power supply, look for the flashing amber LED on the failed power supply that you set to flash in the step to identify the failed part. See Figure 1 and Figure 2 that show the state of the LEDs in a working and failed power supply. Note that the failed power supply has the AC power-on LED On (solid), the DC power-on LED is Off, and the Error amber LED is Flashing, as shown in (C) in Figure 1 and Figure 2.
   Attention: If the power supply is operating correctly then the AC power-on LED and DC power-on LED are On (solid) and the Error amber LED is Off, as shown in (B) in Figure 1 and Figure 2. Do not attempt to remove the working power supply.

3. Label and disconnect the power cord from the power supply by pulling the end of the power cord (A) out of the power supply in the direction that is shown in Figure 3 for a rack-mounted system and Figure 4 for a stand-alone system.
   Note: This system is equipped with redundant power supplies. Before you continue with this procedure, disconnect all power sources to the system.

4. To unseat the power supply from its position in the system, push the terracotta locking-tab (B) in the direction shown in Figure 3 for a rack-mounted system and Figure 4 for a stand-alone system.
5. To release the power cord that is strapped to the handle, unstrap the hook-and-loop fastener (D) and then pull the power cord away from the power supply (C). Ensure to retain the hook-and-loop fastener (D) on the power cord.
6. Pull the power supply (C) away from the system, as shown in Figure 3 for a rack-mounted system and Figure 4 for a stand-alone system.
