Installing and Removing the Power Supply

Caution Follow proper safety procedures when performing these steps by reading the safety warnings in

Regulatory Compliance and Safety Information for the Cisco Intrusion Prevention System 4200 Series

Appliance Sensor.

IPS 4270-20 ships with two hot-pluggable power supplies, thus providing a redundant power supply

configuration. You can install or replace either power supply without powering down the IPS 4270-20,

as long as one power supply is active and functioning correctly.

Caution If only one power supply is installed, do not remove the power supply unless the IPS 4270-20 has been

powered down. Removing the only operational power supply causes an immediate power loss.

To install and remove power supplies, follow these steps:

Step 1 Log in to the CLI.

Note Power supplies are hot-pluggable. You can replace a power supply while the IPS 4270-20 is

running, if you are replacing a redundant power supply.

Step 2 Prepare IPS 4270-20 to be powered off (if you only have one active, functioning power supply). Wait for

the power down message before continuing with Step 3.

sensor# reset powerdown

Note You can also power off the IPS 4270-20 using the IDM or the IME.

Step 3 Power off IPS 4270-20 (if you only have one active, functioning power supply).

Step 4 Remove the power cables from the IPS 4270-20.
