Power Supplies

The Z9500 supports four hot-swappable Power supply units (PSUs) .
NOTE: The PSUs must be installed at the customer site.
PSUs are field replaceable. To ensure power redundancy and adequate cooling, install four power
supplies in the switch. When running with full redundancy (four PSUs installed and running), you can
remove and replace a PSU while the other PSUs are running without disrupting traffic.

Fans

The Z9500 supports five fan trays with airflow directions from I/O to Utility.
The fans must be installed at the customer site.
