1About the BlackDiamond 8800 Series Switches
This chapter describes the Extreme Networks BlackDiamond 8800 series switches and includes the
following sections:
●Overview of the BlackDiamond 8800 Series Switches on page 13
●Full-Duplex Support on page 14
●Management Ports on page 14
●External Compact Flash Memory Card on page 14
●BlackDiamond 8806 Chassis on page 15
●BlackDiamond 8810 Chassis on page 16
For information about installing the BlackDiamond switches, see Chapter 2, “Installing the
BlackDiamond 8800 Series Chassis.”
Overview of the BlackDiamond 8800 Series Switches
The BlackDiamond switches are chassis-based, Ethernet service core switches designed for core
applications.
The features of these switches include:
●Hot-swappable I/O modules that include Gigabit Ethernet copper ports (10/100/1000) and Gigabit
Ethernet fiber ports (SFP), or 10 Gigabit Ethernet ports (SFP+ or XFP)
●Management Switch Fabric Modules (MSMs) that provide the active switching fabric and CPU
control subsystem
●Redundant, load-sharing, hot-swappable power supplies
●Field-replaceable, hot-swappable fan trays
●Auto-negotiation for half-duplex or full-duplex operation on 10/100/1000 Mbps ports
●Load sharing on multiple ports
The BlackDiamond 8800 series switches include two chassis models:
●BlackDiamond 8806 chassis, with slots for installing one or two management modules and up to five
I/O modules
●BlackDiamond 8810 chassis, with slots for installing one or two management modules and up to
nine I/O modules
Two series of modules are available for the BlackDiamond 8800 series switches:
●8800 series
Provides high port density and scalability for mid-sized networks
●8900 series
Provides greater port density and increased backplane bandwidth for large networks

About the BlackDiamond 8800 Series Switches
BlackDiamond 8800 Series Switches Hardware Installation Guide
14
The specific capabilities of the switch are determined by the module series installed in the chassis. For
more information about individual I/O modules and management modules (MSMs), see Chapter 3.
For more information about configuring a BlackDiamond switch, see the ExtremeXOS 12.3 Concepts
Guide and the ExtremeXOS 12.3 Command Reference Guide.
Full-Duplex Support
Extreme Networks switches provide full-duplex support for all ports. Full-duplex support means that
frames can be transmitted and received simultaneously, effectively doubling the bandwidth available on
a link. Most ports on an Extreme Networks switch will auto-negotiate duplex operation in the default
configuration. Gigabit Ethernet fiber ports and 10-Gigabit Ethernet ports operate only in full-duplex
mode in accordance with technical standards.
Management Ports
Each BlackDiamond 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.
External Compact Flash Memory Card
All MSMs in the BlackDiamond 8800 series include a compact flash slot next to the console port. 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 12.3 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 8806 Chassis
BlackDiamond 8800 Series Switches Hardware Installation Guide 15
BlackDiamond 8806 Chassis
The BlackDiamond 8806 chassis includes the following physical features:
●One 6-slot chassis with backplane
●Four dedicated I/O module slots, labeled 1, 2, 5, and 6
●One dedicated MSM slot, labeled 3/A
●One dual-use slot for either an I/O module or MSM, labeled 4/B. (Certain restrictions apply to the
use of slot 4/B. For more information see “Using 8900 Series Modules in the Dual-Use Slots” on
page 106.)
●Power supply bay that accommodates up to six 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
Depending on the MSMs and I/O modules installed, the BlackDiamond 8806 chassis can support up to
128 gigabits per second of bandwidth per slot.
Figure 1 shows the front of a BlackDiamond 8806 chassis equipped with two MSMs and three I/O
modules.

2BlackDiamond 8800 and 8900 Series Modules
This chapter describes modules for the BlackDiamond 8800 series switches and includes the following
sections:
●Overview of the BlackDiamond 8800 and 8900 Series Modules on page 19
●Management Switch Modules (MSM) on page 20
●I/O Modules on page 24
Overview of the BlackDiamond 8800 and 8900 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.
The BlackDiamond 8800 series switches support the modules listed in Table 3.
In general, modules from different series can be used in the same BlackDiamond 8800 series chassis;
however, certain restrictions apply. Table 4 shows supported and unsupported module series
combinations.

CAUTION
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 following MSMs are available for the BlackDiamond 8800 series switches:
●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.
