Accessing the System Board
Accessing the System Board
You must open the chassis to access the system board.
Note
To see translations of the various warnings that appear in this publication, refer to the Regulatory
Compliance and Safety Information document that accompanied this device.
Removing the Chassis Cover on Cisco261x, Cisco262x, Cisco265x, and
Cisco26xxXM
This section describes the procedure for opening the chassis by removing the chassis cover.
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.
Warning
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Statement 1032
Tools Required
You need the following tools to remove and replace the chassis cover:
•
•
Number 2 Phillips screwdriver
Electrostatic discharge (ESD)-preventive wrist strap
Removing the Chassis Cover
To remove the chassis cover:
Step1
Power off the router and unplug the AC power cord. If the router uses a DC power supply, remove power
from the DC circuit with the following steps:
a. Locate the circuit breaker on the panel board that services the DC circuit.
b. Switch the circuit breaker to the OFF position.
Step2
Disconnect all cables from the rear panel of the router.
Before opening the unit, disconnect the telephone-network cables to avoid contact with
telephone-network voltages. Statement 1041
Warning
Step3
Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
equipment end of the wrist strap to the metal back plate of the chassis.
