7.9.2 Removing a DC PSU
Remove a DC PSU before replacing it with a new one.
Before removing one PSU when two PSUs are configured, ensure that the other PSU is
operating properly and supplies power higher than or equal to the power rating of the RH2288
V3, and you do not need to power off the server.
Observe the PSU indicators to check the PSU operating status. For details about the
indicators, see 2.4 Indicators and Buttons.
Procedure
Step 1 Wear an ESD wrist strap. For details, see 1 Safety Instructions.
Step 2 Determine the cabinet number and chassis number of the server to be removed, and label its
panel to prevent misoperations.
