This document describes how to install a memory upgrade to the following Passport CPU modules:
With the Passport 8000 Switch Series Software Release 3.5 and above you must upgrade the 8190SM and the
8690SF to 256MB.
Although it is not required with Release 3.5, Nortel Networks recommends that you upgrade the 8691SF to
256MB to accommodate future capabilities. The 256MB memory upgrade kit (Order No. DS1411016)
contains the following:
• 256 MB dual inline memory module (DIMM).
• 256 MB label to apply to the faceplate of the CPU module
• 3 CPU part number labels See Table 1 to identify the appropriate label to apply to your CPU module pan.
Note: Nortel Networks only supports the 256 DIMM contained in this memory upgrade kit (Order No.
DS1411016). Installing a 256MB DIMM other than the one enclosed in this memory upgrade kit will void any
warranty or maintenance contract on the module.
The 8000 Series modules are sensitive to static electricity. Static discharge from your clothing or other fixtures
around you, even at levels that do not create a spark, can cause damage.
To prevent static discharge damage when you work with 8000 Series modules, place each module on a
grounded antistatic mat until you are ready to install or leave it in the sealed ESD bag.
Wear a discharge leash or wrist strap to free yourself of static before you touch a module.
To upgrade your Passport CPU memory upgrade you must first remove the Passport CPU Module from the
Passport 8000 Series chassis.
To install your Passport CPU memory upgrade you must first remove the Passport CPU Module from the
Passport 8000 Series chassis.
If you have one Passport CPU Module installed in your chassis,
you must power down your switch. If you have two Passport CPU Modules you can remove the Passport CPU
module with the power on or off.
Refer to instructions for turning power off in your chassis installation manual. Refer to Installing 8600 Modules
and use the instructions for removing a module.
Be sure to place the Passport CPU Module on a clean, nonconductive surface.
Removing the DIMM from the Passport CPU Module To upgrade the Passport CPU Module, you must first
remove the installed DIMM.
To remove the DIMM from the Passport CPU Module:
1 Locate the DIMM to remove (Figure 1).
Figure 1 Location of DIMM on the Passport CPU Module
2 Pull the locking tabs on each side of the DIMM outward to unseat the DIMM (Figure 2).
3 Grasp the top corners of the DIMM and pull it out and away from the connector.
This procedure assumes you have already removed the DIMM from the appropriate socket as described in the
Your upgrade kit contains one 256 MB DIMM. To install it:
1 Remove the DIMM from the package and place it on a static-free surface.
2 Holding the DIMM by its top corners (opposite the connector edge), orient the DIMM so that the notches align
with the keys in the DIMM socket (Figure 3).
3 Insert the DIMM into the Passport CPU connector socket and press it in to seat the DIMM firmly in the socket(Figure 4).
4 Press the locking tabs in one at a time to secure the DIMM in its locked position (Figure 5).
Caution: Although it is normal to feel a slight resistance as the DIMM comes to its locked position, be careful not
to use too much force. You may damage the DIMM socket by forcing the DIMM into the locked position.
One 256MB label and 3 CPU part number labels are contained in your memory upgrade kit.
If you need to return your module to Nortel Networks, to ensure rompt servicing please follow these steps to
attach the labels:
1 Remove the paper backing from the 256MB label.
2 Attach the 256 MB label to the CPU module faceplate next to the module model number as shown in Figure 6.
3 Locate the appropriate part number label for your CPU (Table 1).
Table 1 Choosing the appropriate CPU module part number label
4 Remove the paper backing from the appropriate CPU part number label.
5 Attach the appropriate CPU part number label to the bottom of the CPU module as shown in Figure 7.

5 Install the Passport CPU Module in the chassis. To install the Passport CPU module, refer to Installing 8600
Modules and follow the instructions for installing a module
