on each flange must also align with a hole in each side of the 1U fascia.

Installing or replacing a power supply: 2077-92F
Use the following procedures to replace either of the redundant power supplies in the 2077-92F
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.
