3 BlackDiamond 8800 Modules
This chapter describes modules for the BlackDiamond 8800 series of switches and includes the
following sections:
● Management Switch Modules (MSM) on page 53
● MSM LEDs on page 56
● I/O Modules on page 56
● I/O Module LEDs on page 66
Do not attempt to mix and match modules across Extreme Networks product lines. BlackDiamond 8800 series
modules are for use in a BlackDiamond 8800 series switch only, such as a BlackDiamond 8810 or BlackDiamond
8806 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 BlackDiamond 8800 MSMs, the MSM-G8X and the MSM-48, provide the active switching fabric and
CPU control subsystem. 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. Each module also contains a temperature sensor, nonvolatile random-access
memory (NVRAM), and a real-time clock.
The BlackDiamond 8800 MSMs consist of a printed circuit board mounted on a metal panel that acts as
the insertion vehicle in the BlackDiamond 8800 series of switches. The module carrier also includes
ejector/injector levers and captive retaining screws at each end of the module front panel.
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.)
Slots for BlackDiamond 8800 MSMs
MSMs reside in different slots depending on which BlackDiamond switch you operate:
● If you are using only one MSM in the BlackDiamond 8806 switch, install that MSM in slot 3. If you
want to use two MSMs to increase reliability and throughput, install the second MSM in slot 4.
● If you are using only one MSM in the BlackDiamond 8810 switch, install that MSM in slot 5. If you
want to use two MSMs to increase reliability and throughput, install the second MSM in slot 6.
See “Installing a BlackDiamond 8800 or 12800 Series Module” on page 175 for information about how to
install a BlackDiamond 8800 MSM.
