2 BlackDiamond 8800 Series Modules
This chapter describes modules for the BlackDiamond 8800 series of switches and includes the
following sections:
● Overview of the BlackDiamond 8800 Series Modules on page 21
● Management Switch Modules (MSM) on page 21
● I/O Modules on page 25
Overview of the BlackDiamond 8800 Series Modules
Modules available for the BlackDiamond 8800 series switches include management switch modules
(MSMs) and I/O modules. A BlackDiamond module consists of a printed circuit board mounted on a
metal panel that acts as the insertion vehicle in the BlackDiamond 8800 series switches. The module
carrier also includes ejector/injector levers and captive retaining screws at each end of the module front
panel. LEDs on the module front panel provide information about the operating status of the modules.
CAUTION
Do not attempt to mix modules across Extreme Networks product lines. BlackDiamond 8800 series modules are for
use only in a BlackDiamond 8806 or 8810 switch. When a BlackDiamond 8800 series switch is in use,
ExtremeXOS software will not recognize a module from a different product line.
Management Switch Modules (MSM)
The following MSMs are available for the BlackDiamond 8800 series switches:
● MSM-G8X
● MSM-48
● MSM-48c
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. Each MSM provides 192 Gbps of switching throughput through three ASICs.
A compact flash slot allows you to insert an external compact flash memory card. (See Chapter 2 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 of the MSMs 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.
