BlackDiamond 12800 Series Switches Hardware Installation Guide

Each BlackDiamond series Management Switch Fabric Module (MSM) has a 10/100BASE-TX Ethernet 
management port. This port allows you to communicate directly with the central processing unit (CPU) 
of the switch. You can plug an Ethernet cable directly from your laptop into the management port, for 
direct access into the switch. This access allows you to view and locally manage the switch 
configurations. 

All MSMs in the BlackDiamond family include a compact flash slot next to the console port on the 
MSM. This slot accepts a compact flash memory card, which can be used to download a new version of 
ExtremeXOS and for other functions, including capturing debug information and core dump files. See 
the ExtremeXOS 12.0 Concepts Guide for more information regarding the use of the external compact 
flash memory card.

The external compact flash slot supports third party compact flash cards.

The BlackDiamond 12804 chassis consists of the following components:

●

One 6-slot chassis with backplane

●

Four dedicated I/O module slots, labeled 1, 2, 5, and 6

●

Two MSM slots, labeled 3/A and 4/B

●

Up to six SSI redundant AC/DC power supplies, accessed from the front of the unit

●

One fan tray, accessed from the front right of the unit

●

One connector for an ESD-preventive wrist strap

●

Two PSU/fan controllers that collect and report data from the installed power supply units and the 
BlackDiamond fan tray. The PSU/fan controllers intervene in the event of power inconsistencies and 
provide primary/backup redundancy if a BlackDiamond 12804 PSU/fan controller fails.
