Compact Flash Memory Card Installation and Removal
Perform the procedure below for installing or removing a Compact Flash memory card mounted
internally on the router CPU/mainboard. To access the internal Compact Flash memory card, you need
to remove the chassis cover.
Removing the Chassis Cover
This section describes how to remove the chassis cover to access the Compact Flash memory card. You
need a number 2 Phillips or flat-blade screwdriver to perform this procedure.
Observe the following precaution if your router uses AC or DC power:
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 translations of the various
warnings that appear in this publication, refer to the Regulatory Compliance and Safety
Information document that accompanied this device.
Observe the following precaution if your router uses DC power:
Warning
Before performing any of the following procedures, ensure that power is removed from 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 translations of the various warnings that appear in this
publication, refer to the Regulatory Compliance and Safety Information document that
accompanied this device.
Perform the following procedure to remove the chassis cover:
Step 1 Power OFF the router. However, to channel ESD voltages to ground, do not unplug the power cable.
Warning
Before opening the chassis, disconnect the telephone-network cables to avoid contact with
telephone-network voltages. 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.
Step 2 Disconnect all network interface cables from the rear panel.
Step 3 Place the router on a flat surface. Remove the five screws located on top of the cover. Set the screws aside
in a safe place.
Step 4 Rotate the cover up to a 45-degree angle. (See Figure 33.)
• Slide the cover to the side (away from the side with the fans) until the tabs are free from the slots.
(See Figure 33.)
