Installing or replacing a power supply: 2145-92F
Use the following procedures to replace either of the redundant power supplies in the 2145-92F
expansion enclosure. The redundant power supplies operate in parallel; one continues to provide power
to the enclosure if the other fails.
Before you begin
Important: You can replace a PSU without powering off the expansion enclosure. However, to maintain
operating temperature, replace the PSU within 10 minutes of its removal. When a PSU is removed, the
reduction in airflow through the enclosure might cause the enclosure or its components to shut down to
protect from overheating.
About this task
This task assumes that the following conditions are met:
• You removed the PSU, following the procedure described in “Removing a power supply: 2145-92F ” on
page 100.
• You removed the fascia that covers the PSU from the front of the expansion enclosure, as described in
“Removing the fascia: 2145-92F ” on page 85.
• You are aware of the procedures for handling static-sensitive devices.
Procedure
1. Read all safety information.
2. Rotate the handles on the PSU outward, as shown in Figure 92 on page 83.
