Learn how to install a redundant power supply with the
system power turned on, if your system was shipped with only one power
supply.
If you are servicing a failing part, see the service procedures
for Removing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D power supply with the power turned on or Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D power supply with the power turned on.
Before installing or replacing a feature, ensure
that the software required to support the feature is installed on
your system.
For information about software prerequisites, see IBM Prerequisite. If the required software is
not installed, see the following websites to download it, and then
install it before continuing:
If your system
is managed by the HMC,
use the HMC to install a power supply. For instructions, see Installing
a part by using the Hardware Management Console.
If
your system is not managed by an HMC, complete
the following steps to install a redundant power supply in a system
while the system power is turned on.
Important: You must
have a functioning power supply in the system to perform the following
steps.
- Complete the prerequisite tasks.
For instructions, see Before
you begin.
- Attach the wrist strap.
Attention: - Attach a wrist strap to an unpainted metal surface of your hardware
to prevent electrostatic discharge (ESD) from damaging your hardware.
- When using a wrist strap, follow all electrical safety procedures.
A wrist strap is for static control. It does not increase or decrease
your risk of receiving electric shock when using or working on electrical
equipment.
- If you do not have a wrist strap, just prior to removing the product
from ESD packaging and installing or replacing hardware, touch an
unpainted metal surface of the system for a minimum of 5 seconds.
- For a rack-mounted system, place the system into the service
position. For instructions, see Placing
a rack-mounted 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C,
or 8205-E6D system
in the service position.
- Remove the power supply filler by pushing down the locking
lever and pull out the filler.
- Align the power supply with the bay and slide the new power
supply into the system until the latch locks in place, as shown in Figure 1.
Figure 1. Installing a power supply
- Route the power cable through the cable management bracket
at the rear of the power supply, as shown in Figure 2.
Figure 2. Routing the power cable
If you are installing the power supply
as part of another procedure, return to that procedure now. If your
service actions are completed, continue with the following steps:
- Connect the power source.
- Place the rack-mounted system into the operating position. For
instructions, see Placing
a rack-mounted 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C,
or 8205-E6D system
into the operating position.
- Note the state of the light-emitting diodes
(LEDs) on the power supply. For more information, see Power supply
LEDs for the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C,
or 8205-E6D.
- If the LEDs indicate that the power supply is operating normally,
that is both of the green LEDs are on solid (not flashing), continue
to the next step.
- If the LEDs indicate that the power supply is not operating correctly,
remove the power supply from the system and repeat the procedure.
- If, after repeating the procedure, the power supply is not operating
normally, contact your service provider.
Verify the installed
part or repair:
- If you replaced the part because of a service action, verify the
installed part. For instructions, see Verifying
a repair.
- If you installed the part for any other reason, verify the installed
part. For instructions, see Verifying
the installed part.
