BlackDiamond 8800 Series Switches Hardware Installation Guide
21
Do not attempt to combine modules from the BlackDiamond 8800 series and BlackDiamond 12800 series
product lines. When a BlackDiamond 8800 series switch is running, ExtremeXOS software will not recognize an
installed BlackDiamond 12800 series module.
Management Switch Modules (MSM)
The BlackDiamond 8800 series switches support the following MSMs:
● 8500-MSM24
● 8800 series MSMs
-MSM-G8X
-MSM-48
-MSM-48c
● 8900-MSM128
The MSMs provide the active switching fabric and CPU control subsystem for the switch. One MSM is
required for switch operation; however, adding a second MSM to the chassis increases reliability and
throughput.
A compact flash slot allows you to insert an external compact flash memory card. (See “External
Compact Flash Memory Card” on page 14 for more information about Extreme Networks-supported
compact flash cards.)
Redundant MSM Activity
The BlackDiamond 8800 series switches can run with a single MSM installed. When you install an
additional MSM, one MSM operates as the primary MSM and the other becomes the backup
(secondary) MSM. The primary MSM is responsible for upper-layer protocol processing and system
management functions. Packet handling is distributed among the CPUs of all installed MSMs.
When you save the switch configuration, it is saved to all MSMs.
