Appendix B

Installing the Metro Ethernet enhanced CPU daughter card

This appendix describes how to install the optional Metro Ethernet enhanced CPU daughter card (hereafter referred to as the daughter card or SuperMezz) on the 8692 Series CPU modules (8692SF and 8692omSF) .

The SuperMezz is a mezzanine daughter card that consists of dual 1 GHz Power PC processors. Installing the daughter card on an 8692 Series module offloads processor-intensive tasks from the 333 MHz processor located on the 8692 CPU.

Prerequisites

All Metro Ethernet Services Modules (Metro ESM 8668) in your chassis must have a jumper installed.

CAUTION

Before installing the SuperMezz, all Metro ESM 8668 modules in your chassis must have a jumper installed. See "Installing the jumper on an ESM 8668" (page 139) for directions on how to install the jumper.

The SuperMezz is only supported on the 8692 Series CPU modules.

The SuperMezz is required for Provider Backbone Transport (PBT) services.

In a system with two 8692SF CPU modules (or two 8692omSF CPU modules), you must install a SuperMezz on both CPU modules.

Do the following to protect your equipment from electrostatic discharge.
