Installing or Replacing a Power Supply

Note Figure 1-5 on page 1-9shows two different power supplies (one AC and one DC) together in a Cisco ADE 2130 and 2140 Series appliance for illustration purposes, only. An actual configuration cannot combine two different power supplies; the appliance would include either two AC modules (or an AC module and a blank filler panel), or two DC modules (or a DC module and a blank filler panel).

This section includes the following topics

Replacing a Redundant Power Supply

If you have two power supplies (AC or DC) installed in your Cisco ADE 2130 and 2140 Series appliance, one of the modules is redundant, enabling you to hot-swap one of the power modules (replace a module without powering down the system), if you need to replace one of the power supplies.

To replace a redundant power supply:

Step 1 Check the status LED on the power supplies (see location 2 in Figure 4-9 on page 4-18) to determine which power supply has failed.

Step 2 Disconnect the appropriate AC or DC power source.
