Replacing DIMMs

Step 6 Using your fingers, gently extract the old compact flash and set it on a nonconductive surface. Do not use excessive force, because the socket might break.

Step 7 Insert the new compact flash into the socket. Be careful not to bend or crush any of the bottom pins. If necessary, use needlenose pliers to straighten out any bent pins.

Step 8 Replace the chassis cover. (See the instructions in the “Replacing the Chassis Cover” section on page A-8.)

Step 9 Power up the universal gateway. If error messages relating to memory are displayed, remove the new compact flash and reinstall it, taking care to seat the compact flash firmly in the socket.

Replacing DIMMs

This section describes how to replace a DIMM on the Cisco AS5350XM universal gateway. The universal gateway has a single DIMM (see Figure A-4). The default factory configuration is a 512 MB double data rate (DDR1) SDRAM DIMM.

You might need to upgrade the DIMM for the following reasons:

You have upgraded to a new Cisco IOS feature set or release that requires more memory.

You are using very large routing tables or many protocols (for example, when the universal gateway is set up as a connection device between large external networks and your internal network).

Required Tools and Equipment

You need the following tools and equipment:

ESD-preventive wrist strap

Appropriate DIMM

Replacing the DIMM

To replace the DIMM, follow this procedure:

Step 1 Power down the universal gateway and disconnect site power.

For DC-powered units only, note the following warning.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning Before connecting or disconnecting ground or power wires to the chassis, 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. Statement 140
