Cisco 3600 Series Power Supply Configuration Note 7

Removing the Cover

To gain access to the power supply of a Cisco 3600 series router, you must ﬁrst remove the chassis

cover.

Warning Before working on a chassis or working near power supplies, unplug the power cord on

AC units; disconnect the power at the circuit breaker on DC units. (To see translated versions of this

warning, refer to the Regulatory Compliance and Safety Information document that accompanied the

router.)

Warning Do not touch the power supply when the power cord is connected. For systems with a

power switch, line voltages are present within the power supply even when the power switch is off

and the power cord is connected. For systems without a power switch, line voltages are present

within the power supply when the power cord is connected. (To see translated versions of this

warning, refer to the Regulatory Compliance and Safety Information document that accompanied the

router.)

Step 1 Turn OFF power to the router.

the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that

services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of

the circuit breaker in the OFF position. (To see translated versions of this warning, refer to the

Regulatory Compliance and Safety Information document that accompanied the router.)
