Removing and Installing Components
Removing and Installing DC Power Supplies
This section provides instructions for removing and installing the DC power supplies for the Cisco MDS
9100 Series switch.
Note The new DC power supply is not supported on the Cisco MDS 9140 Switch and the Cisco MDS 9120
Switch.
Caution Power supplies for the Cisco 9100 Series switches look similar but they differ slightly. Be sure to use
the correct power supply designated for your Cisco 9100 Series switch. Using an incorrect power supply
will not provide redundant power in the case of a power supply failure.
Removing Power Supplies
Note The new DC power supply does not have a built-in power switch, unlike the AC power supply.
To remove a DC power supply, follow these steps:
Step 1 Turn the power switch to the off (0) position on the actual DC power source.
Step 2 Disconnect the power cord from the power source.
Step 3 Loosen the captive screw.
Step 4 Grasp the power supply handle and slide the power supply out of the switch. See Figure 2-23.
