switch, see Chapter 3, “BlackDiamond 10808 Series Modules.”.
For information about installing the BlackDiamond 10808 switch, see Chapter 2.
Overview of the BlackDiamond 10808 Switch
The BlackDiamond 10808 switch is a chassis-based, Ethernet service core switch designed for core
applications.
The features of this switch 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 (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
For more information about configuring a BlackDiamond switch, see the ExtremeXOS 12.1 Concepts
Guide and the ExtremeXOS 12.1 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, which, in effect, doubles the bandwidth
available on a link. Most ports on an Extreme Networks switch will auto-negotiate duplex 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 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.
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 12.1 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 10808 Switch Chassis
The BlackDiamond 10808 switch chassis includes the following components:
●One 10-slot chassis with backplane
●Eight I/O module slots, labeled 1 through 8
●Two MSM slots, labeled A and B
●Up to six power supplies, accessed from the front of the unit)
●Two hot-swappable fan trays, accessed from the back of the unit. Each fan tray contains two fans.
●One connector for an ESD-preventive wrist strap
Software monitors the fan trays in the BlackDiamond 10808 switch for overheating. All
over-temperature events cause the switch to send alerts to the network management station or to the
switch log. See the ExtremeXOS 12.1 Concepts Guide for more information about switch monitoring.
CAUTION
Do not cover or obstruct the fan ventilation holes at the rear of the unit. Doing so can result in overheating and
possible damage to the BlackDiamond 10808 switch. Thermal sensors will shut down the BlackDiamond 10808
switch if the internal temperature exceeds 60 degrees Celsius.
The BlackDiamond 10808 switch includes two power supply controllers, located in the back of the
chassis, that collect data from the installed power supplies and report the results to the MSM modules.
The power supply controllers provide primary/backup redundancy in case one of the controllers fails
or is removed. At least one power supply controller must be installed.

BlackDiamond 10808 Switch Chassis
BlackDiamond 10808 Switch Hardware Installation Guide 15
When the BlackDiamond 10808 switch is first powered on, the power supply controllers enable the
power supplies by providing 48V power. The power supply controller also detects and reports
incompatible combinations of power supply types and line voltage feeds and disables the power supply
if an unsafe condition arises.

2BlackDiamond 10808 Series Modules
This chapter describes the I/O modules and the Management Switch Module (MSM) that are installed
in the BlackDiamond 10808 switch chassis. The chapter includes the following sections:
●Overview of the BlackDiamond 10808 Modules on page 17
●Management Switch Modules (MSMs) on page 17
●I/O Modules on page 20
For instructions on installing the BlackDiamond 10808 modules, see Chapter 4, “Installing
BlackDiamond 10808 Modules.”
Overview of the BlackDiamond 10808 Modules
Modules available for the BlackDiamond 10808 switch 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 10808 switch. 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.
Management Switch Modules (MSMs)
The BlackDiamond MSM holds the control plane and the switch fabric for the switch. In addition, each
MSM has two CPUs for protocol processing and network management. The BlackDiamond 10808
chassis has two slots for installing MSMs. Although the system will operate with a single MSM,
bandwidth is reduced. Two MSMs are required for full system bandwidth.
The following MSMs are available for the BlackDiamond 10808 switch:
●MSM-1
●MSM-1XL
The MSM-1 and MSM-1XL have different size Ternary Content Addressable Memory (TCAM). The
MSM-1XL has more memory available for routing tables, learned MAC addresses, and access control
lists (ACLs). For specific details about memory allocation, refer to the data sheet for each module.
MSMs are installed in designated lettered slots in the BlackDiamond 10808 chassis.
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.).

BlackDiamond 10808 Series Modules

Redundant MSM Activity
The BlackDiamond 10808 switch can operate with a single MSM installed. When you install a second
MSM, one of the MSMs operates as the primary, and the other becomes the backup.
The primary MSM is responsible for upper-layer protocol processing and system management
functions. For example, OSPF computation and SNMP functions are performed by the primary MSM.
Packet handling is distributed among the CPUs of all installed MSMs.
When you save the switch configuration, it is saved to all MSMs. If you download a new ExtremeXOS
image, the image is downloaded to all MSMs.
Selection of the primary MSM occurs automatically. The following examples describe the selection
process:
●When the BlackDiamond 10808 switch boots with two MSMs already installed, the MSM in slot A
becomes the primary MSM.
●When the BlackDiamond 10808 switch boots with a single MSM (regardless of the slot position), it is
selected as the primary MSM.
If a second MSM is added to the switch after it has been powered on, the added MSM becomes the
backup MSM. MSMs that operate as backups can be inserted and removed without disrupting
network services.
●If you remove the primary MSM while the BlackDiamond 10808 switch is operating, the backup
MSM performs a soft reset and then becomes the primary MSM.
For example, in a BlackDiamond 10808 switch with a primary MSM in slot A and a backup MSM in
slot B, if you remove the primary MSM from slot A, the backup MSM in slot B becomes the primary
MSM.

I/O Modules
The following I/O modules are available for the BlackDiamond 10808 switch:
●G60T Module
●G60X Module
●G20X Module
●10G6X Module
●10G2X Module
●10G2H Module
NOTE
On the BlackDiamond 10808 switch, the 10 Gbps module (10G6X module) must have the serial number 804405-
00-09 or higher to support untagged frames. To display the serial number of the module, use the
show slot <slot_number> command. (All the modules on the Black Diamond 8800 series of switches, as well as the
Summit X450 switch, support tagged and untagged frames.)
No configuration information is stored on the I/O modules; all configuration information is stored on
the MSM(s).
When the BlackDiamond 10808 switch is powered on, the software generates a default configuration for
any slots that contain I/O modules. The default configuration allows the I/O module ports to
participate in the VLAN named default. The default configuration for the I/O module is not preserved
unless you explicitly save the configuration to nonvolatile RAM (NVRAM).
You can configure parameters of the I/O module after it is installed or you can preconfigure a slot for a
certain type of module and configuration. The preconfigured information is applied to the module after
it is inserted. If you preconfigure a slot for a specific module type, and then insert a different type of
module, the inserted module reverts to its default configuration.
NOTE
See the ExtremeXOS 12.1 Concepts Guide and the ExtremeXOS 12.1 Command Reference Guide for more
information about configuring I/O modules.
