Cisco Systems 78-10588-03 manual Removing the Power Supply Module, Power On/Off

Chapter 3 Installing the Chassis

Removing the Power Supply Module

•Cover the connector adapters to avoid soiling or contaminating the inside of the adapters while cleaning the chassis.

•Cover the connectors and adapters to avoid the inside of the adapters or the surface of the connectors from getting dirty when not using the connectors.

Note If the surface is not clean or does not have a uniform shine, repeat the process using a fresh surface of the alcohol pad.

Removing the Power Supply Module

This section describes how to power on the system, determine whether a power supply module (PSM) is faulty, and how to replace a PSM, if necessary.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

The Cisco Metro 1500 series system has two identical, fully redundant PSMs. Each PSM can cover the power needs of the entire system. These PSMs provide 5V and 30A to the system. The PSM provides full input-to-output, input-to-case, and output-to-output isolation.

Power On/Off

Caution If powered off, wait at least 10 seconds before you switch the unit on again.

Turn the power on or off using the keyswitch on the AC-powered version only. (See Figure 3-10.) This switch supplies power to the redundant power supplies. You can only move the switch to the on ( ) or off ( 0 ) position. Two keys are shipped with each unit and all units use the same key. You can remove the key in either the on or off position.
