About the BlackDiamond 12800 Series Switches
Management Ports
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.
Appropriate shielded Ethernet cables are available from your local supplier, or you can make your own.
To ensure the electromagnetic compatibility of the unit, use only shielded cables that are grounded on
both ends.
External Compact Flash Memory Card
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.
NOTE
You must use an industrial-grade compact flash card in the external compact flash slot of the MSM.
BlackDiamond 12804 Switch Chassis
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
