Installing Ac Power Supplies - Dell Networking Z9500 Getting Started Manual

Installing AC Power Supplies

The chassis requires four power supplies to be installed for normal configuration. The airflow direction
must be from I/O to Utility.
Important Points to Remember for Installing an AC Power Supply
• The power supply unit (PSU) slides into the slot smoothly. Do not force a PSU into a slot as this action
may damage the PSU or the chassis.
• The chassis supports AC power supplies with air-flow direction from I/O to Utility.
• 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.
