Procedures
Removing a power supply unit
1.
If replacing a single power supply module via hot-swap, proceed to step 3.
2.
If replacing both power supply modules, verify that the enclosure is powered off.
If the PSU model has a power switch, verify that the switch is set to the
Off
position.
3.
Verify that the power cord is disconnected.
4.
Turn the thumbscrew at the top of the latch counterclockwise to loosen and disengage it from the
module; however, do not remove the thumbscrew from the latch.
5.
Rotate the latch downward by approximately 45
, supplying sufficient leverage to disconnect the
module from the internal connector.
See
