Installation manual

• For PSUs, a LED indicates the power status.

• To view the log messages, use the show logging command. For more information, refer to the

System Logs chapters of the Dell Networking OS Command Line Reference Guide for the Z9500

Switch and Dell Networking OS Configuration Guide for the Z9500 Switch.

WARNING: Although the switch can run on two PSUs, Dell Networking requires using four PSUs

for full redundancy and proper cooling.

WARNING: The Utility panel consists of four slots numbered from 0 to 3. Insert PSUs in slots 0, 1,

2, and 3.

WARNING: The PSU edge connector is at the bottom. Avoid installing the PSU upside down.

WARNING: Electrostatic discharge (ESD) damage can occur if components are mishandled.

Ground yourself by using an antistatic wrist strap or other device and connect it to the ESD

grounding jack on the chassis.

1. Remove the PSU from the electro-static bag.

2. Use the grab handle to slide the PSU into the switch PSU slot. The PSU slot is keyed so that the PSU

can be fully inserted in only one way. When you install the PSU correctly, it snaps into place and is

flush with the back of the switch.
