Installing or Replacing a Power Supply
Note Figure 1-5 on page 1-9 shows 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.
