C-14 Cisco 4000 Series Installation Guide

Replacing the Cisco 4500-M and Cisco 4700-M Boot Helper Flash Memory SIMM

Step 3 Pull the locking spring clips on both sides outward and tilt the SIMM free of the

clips to lift the SIMM out of its socket. (See Figure C-7.)

Proceed to the next section, “Installing Flash-Memory SIMMs.”

Installing Flash-Memory SIMMs

Take the following steps to add Flash memory SIMMs:

Step 1 On the motherboard, locate the Flash-memory SIMM sockets shown in

Figure C-1 and Figure C-2.

Caution Handle SIMMs by the edges only. SIMMs are ESD-sensitive components and

can be damaged by mishandling.

Step 2 Hold the SIMM with the polarization notch on the right and the component side

away from you with the connector edge at the bottom.

Step 3 Referring to Figure C-8, insert the Flash-memory SIMM at a 45-degree angle and

rock it into its vertical position. (See Figure C-1 and Figure C-2.) When the SIMM

is properly seated, the socket guide posts will insert through the alignment holes,

and the locking springs will click into place. Use the minimum amount of force

required.

Caution You will feel some resistance, but do not use excessive force on the SIMM and

do not touch the surface components to avoid damaging them.

Step 4 Check the alignment of each SIMM to make sure that it is straight and that the

alignment holes are lined up with the plastic socket guides.

If you have completed all memory upgrade procedures, proceed to the section “Replacing

Network Processor Modules” in the chapter “Conﬁguring the Cisco 4000 Series Chassis.”
