7.10.2 Installing a DC PSU
Install a DC power supply unit (PSU) to replace the original one.
A DC PSU needs to be added to improve reliability when the 5288 V3 is configured with only
one DC PSU.
Procedure
Step 1 Wear an ESD wrist strap. For details, see 1 Safety Instructions.
Step 2 Remove the PSU to be replaced. For details, see 7.9.2 Removing a DC PSU.
Step 3 Take the spare DC PSU out of its ESD bag.
Step 4 Push the spare DC PSU along the guide rails into a slot (for example, slot 1) until you hear a
sound.
The PSU latch snaps in so that the PSU does not move. See Figure 7-21.
