Cisco MDS 9134 Switch has two hot-swappable power supplies and two hot-swappable fan modules.

The Cisco MDS 9124 Switch is shipped with one field-replaceable power supply and three fixed fans.

The Cisco MDS 9134 switch and the Cisco MDS 9124 switch support the new DC power supply.

Warning

Hazardous voltage or energy is present on the backplane when the system is operating. Use

caution when servicing. Statement 1034

During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.

Caution

Except for the Cisco MDS 9124 switch, all the the other Cisco MDS 9100 Series switches are supported

Note

for operation with both power supplies and both fan modules installed, and with all fans working.

With two power supplies installed, if one power supply fails, the system can continue to function

normally on a single healthy power supply. However, the failed power supply should be replaced as soon

as possible to provide redundancy.

The fan modules are required to ensure proper cooling of the switches. See
