Cisco MGX 8950 Hardware Installation Guide
Release 3, Part Number 78-14147-02 Rev. A0, November 2002
Chapter 1 Product Overview
System Hardware Components
Table 1-7 describes LEDs on the PXM45/Bs.
Note For information on PXM45/B software features and configurations, refer to the Cisco MGX 8850
(PXM45) and MGX 8950 Switch Software Configuration Guide.
Module Configurations
PXM45/B card redundancy is preconfigured on the Cisco MGX switches. If PXM45/Bs are inserted in
both slots
7 and 8, they automatically operate as redundant cards. If you install only one PXM45/B in
the switch, it operates as a standalone card. We recommend installing two to provide fault tolerance for
the PXM45/B. If one card goes down, a redundant card takes over.
Note To operate redundantly, Y-cabling must be present on the external clock ports on the back cards.
