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.
