Preventing Electrostatic Discharge Damage
Preventing Electrostatic Discharge Damage
Memory SODIMMs are sensitive to electrostatic discharge (ESD) damage. ESD damage, which can
occur when electronic cards or components are handled improperly, results in complete or intermittent
failures.
To prevent ESD damage, follow these guidelines:
Caution
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
Connect the equipment end of the strap to an unfinished chassis surface.
•
Place a removed memory SODIMM on an antistatic surface or in a static shielding bag. If the
memory SODIMM will be returned to the factory, immediately place it in a static shielding bag.
•
Avoid contact between the memory SODIMM and clothing. The wrist strap protects the memory
SODIMM from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
•
Do not remove the wrist strap until the installation is complete.
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms (Mohms).
Tools and Equipment Needed
You need the following tools and equipment to remove and install memory SODIMMs:
•
ESD-preventive wrist strap
•
Antistatic bag or mat
•
Number 2 Phillips screwdriver
•
Small flat-blade screwdriver
Installing a Memory SODIMM
To install a memory SODIMM, you need to remove the network module from the router chassis and then
remove the expansion module from the network module.
To install a memory SODIMM, complete the following procedure.
Step 1
If the network module contains an expansion module with a small computer systems interface (SCSI)
controller, disconnect the cable from the front of the network module.
Step 2
Remove the network module from the router chassis (refer to the Cisco Network Modules Hardware
Installation Guide).
Caution
If your router is a Cisco 2600 series, Cisco 3620, or Cisco 3640, you must turn off the power to the
router before you remove the network module, as described in the “Installing Network Modules”
chapter of the Cisco Network Modules Hardware Installation Guide. Cisco 3660 and Cisco 3700
series routers support hot swapping of network modules, so you can remove network modules from
those routers without turning off the power.

Installing a Memory SODIMM
Step 3
Caution
Place the network module on an ESD-protected surface.
Minimize contact with the bottom of the network module to avoid damage to components located on the
bottom of the card.
Step 4
If the network module contains an expansion module with a SCSI controller, use a small flat-blade
screwdriver to remove the two connector screws from the connector in the front panel (see Figure 1).
Step 5
Using a Phillips screwdriver, remove the expansion-module screw from the front panel (see Figure 1 or
Figure 2) and the two screws on the top of the expansion module (see Figure 3 or Figure 4).

Carefully unplug the expansion module and lift it away from the network module.
Note
Expansion modules with a disk drive have two connectors that plug into the network module—one
at the front and one at the rear. Expansion modules with a SCSI controller have one connector that
plugs into the network module—located at the rear.
Tip
For expansion modules with a SCSI controller, confirm that the connector has been removed from the
opening in the faceplate before you lift the expansion module away from the network module.

Step 8
If the memory SODIMM is in the upper slot of the SODIMM connector, remove the memory SODIMM
and reinstall it in the lower slot as follows:
a.
Carefully spread the clips at each edge to release the SODIMM.
b.
Lift the SODIMM up slightly and remove it from the SODIMM connector.
c.
Hold the SODIMM so that it is angled upward about 30 degrees from horizontal, and insert it into
the lower slot of the SODIMM connector until it is completely seated. The notch in the SODIMM
prevents incorrect orientation.
d.
Carefully press the SODIMM into place so that the clips latch on both edges. The SODIMM must
be horizontal when properly installed.
Install the new memory SODIMM in the upper slot of the SODIMM connector as follows:
a.
Hold the SODIMM so that it is angled upward about 30 degrees from horizontal, and insert it into
the upper slot of the SODIMM connector until it is completely seated. The notch in the SODIMM
prevents incorrect orientation.
b.
Carefully press the SODIMM into place so that the clips latch on both edges. The SODIMM must
be horizontal when properly installed.

Step 9
Caution
Note
Plug the expansion module into the network module. Expansion modules with a disk drive have two
connectors that plug into the network module—one at the front and one at the rear. Expansion modules
with a SCSI controller have one connector that plugs into the network module—located at the rear. See
Figure 3 or Figure 4.
Align the connectors carefully and use gentle pressure when installing an expansion module.
Misalignment or excessive force can damage connector pins or other board components.
For expansion modules with a SCSI controller, be sure to insert the connector on the expansion
module through the opening in the faceplate before you seat the expansion module.
Step 10
Using a Phillips screwdriver, reinstall the expansion-module screw in the front panel and the two
standoff screws.
Step 11
For expansion modules with a SCSI controller, insert the two connector screws (see Figure 1) into the
holes on the connector, and tighten the screws carefully using a small flat-blade screwdriver.
Step 12
Install the network module into the router chassis and connect the network module to the network (refer
to the Cisco Network Modules Hardware Installation Guide).

Obtaining Technical Assistance
Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance
with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC
Web Site and the Cisco TAC Escalation Center.
Cisco TAC inquiries are categorized according to the urgency of the issue:
•
Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration.
•
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably
impaired, but most business operations continue.
•
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects
of business operations. No workaround is available.
•
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations
will occur if service is not restored quickly. No workaround is available.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of
service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time.
The site provides around-the-clock access to online tools, knowledge bases, and software. To access the
Cisco TAC Web Site, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a
Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or
password, go to this URL to register:
http://www.cisco.com/register/
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC
Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.
