Cisco Systems AS5350XM ユーザーズマニュアル

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.

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.

Replace the chassis cover. (See the instructions in the 

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.

This section describes how to replace a DIMM on the Cisco AS5350XM universal gateway. The 
universal gateway has a single DIMM (see 

). 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). 

You need the following tools and equipment:

ESD-preventive wrist strap

Appropriate DIMM

To replace the DIMM, follow this procedure:

Power down the universal gateway and disconnect site power.

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

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

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
