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

Caution Handle SIMMs by the card edges only. SIMMs are sensitive components and can

be shorted by mishandling.

Step 7 To insert a SIMM, angle it into position, then carefully push down and back on the

edges, holding each edge so that it securely snaps into place. (See Figure C-6.)

When it snaps into place, the two metal holders clip over the edge of the SIMM,

and it sits horizontally.

Caution Avoid damage to the SIMMs and SIMM socket by handling them gently. The

SIMMs are also sensitive to ESD damage.

Step 8 Check that the SIMM is straight and that the holes are aligned with the socket

guide posts on the socket. (See Figure C-6.)

If you are done with all SIMM replacement procedures, proceed to the section “Replacing

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

Replacing the Cisco 4500-M and Cisco 4700-M Boot

Helper Flash Memory SIMM

The boot helper image (Rxboot image) is stored in Flash memory on the Cisco 4500-M and

Cisco 4700-M. (See Figure C-7.)

You upgrade boot helper Flash memory by replacing the existing SIMM (labeled

SYSTEM FLASH MEMORY 0), or by adding a second SIMM to the empty socket

(labeled SYSTEM FLASH MEMORY 1).
