Installing a 256-MB SDRAM DIMM Memory Card in the NM-CUE Network Module

NM-CUE network modules have 256 MB of SDRAM installed on the system board. You can install an
additional SDRAM DIMM in the SDRAM DIMM connector to expand system memory to a maximum
of 512 MB.

Caution When you remove or install DIMMs, always wear an ESD-preventive wrist strap, and ensure that it

makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the
chassis.

Caution Handle SDRAM DIMMs by the edges only. DIMMs are ESD-sensitive components and can be damaged

by mishandling.

SDRAM DIMMs have a polarization notch on the mating edge to prevent incorrect insertion. Figure 2
shows the polarization notch on an SDRAM DIMM.

To install a 256-MB SDRAM DIMM memory card in the NM-CUE network module, follow these steps:

Step 1 Remove the daughter card from the NM-CUE system board. (See Figure 1.)

Step 5

Carefully and firmly press the 256-MB SDRAM DIMM into the connector until the latches close onto
the SDRAM DIMM. Make sure that both latches rotate to the closed position against the SDRAM
DIMM. (See Figure 3.)

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you can perform these tasks:

• Report security vulnerabilities in Cisco products.

• Obtain assistance with security incidents that involve Cisco products.

• Register to receive security information from Cisco.

A current list of security advisories and notices for Cisco products is available at this URL:

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:

• Emergencies— [e-mail]

• Nonemergencies— [e-mail]

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive

information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one that has the most recent creation date in this public key server list:

http://pgp.mit.edu:11371/pks/lookup?search=psirt%40cisco.com&op=index&exact=on

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Obtaining Technical Assistance

Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical
Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical
Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service
contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and
resolving technical issues with Cisco products and technologies. The website is available 24 hours a day,
365 days a year, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password.
If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting

a web or phone request for service. You can access the CPI tool from the Cisco Technical Support
Website by clicking the Too l s & Re s o u rc e s link under Documentation & Tools. Choose Cisco Product

Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product
Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID

or model name; by tree view; or for certain products, by copying and pasting show command output.
Search results show an illustration of your product with the serial number label location highlighted.
Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
