●I/O modules that are hot-swappable and include Gigabit Ethernet fiber ports (SFP), or 10-Gigabit
Ethernet ports (XFP)
●Up to 64 line-rate 10- Gigabit Ethernet ports in one chassis
●Redundant management modules that provide the CPU control subsystem
●Redundant switch fabric modules that provide the active switching fabric
●Redundant, load-sharing, hot-swappable power supplies
●Redundant 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
●120 Gbps switch fabric capacity per I/O module
BlackDiamond 20808 Chassis
The BlackDiamond 20808 switch chassis has the following physical features:
●Height of 14.5 RU, allowing three switches to be installed in a 7-foot rack
●Optional mid-mount brackets for flexibility in rack positioning
●Ten vertical module slots in the front:
■Two dedicated management module slots, labeled A and B
■Eight I/O module slots, labeled 1 through 8
●Five horizontal chassis slots in the back for switch fabric modules

●Five bays for redundant AC or DC power supplies, accessible from the back
●Two fan trays:
■One under the front card cage and accessible from the front
■One above the switch fabric modules and accessible from the back
●Two connectors for an ESD-preventive wrist strap:
■One at the top right corner of the front panel
■One above the right side of the switch fabric modules
●Air filters for the chassis air intake and for the switch fabric modules

Overview of the BlackDiamond 20808 Modules
Modules for the BlackDiamond 20808 switch include management modules, I/O modules, and switch
fabric modules.
Each module for the BlackDiamond 20808 switch consists of a printed circuit board mounted on a metal
panel that acts as the insertion vehicle in the switch. The module carrier also includes ejector/injector
levers and captive retaining screws at each end of the module front panel.
Table 3 lists the module types and models available for the BlackDiamond 20808 switch.
Management Modules
Two BlackDiamond 20808 management modules are available, the MM-Base and the MM-Adv. The
MM-Adv management modules support larger MAC address, IP route, and ACL capacity than the
MM-Base. Management modules provide the CPU control subsystem for the switch.
The BlackDiamond 20808 switch has two dedicated management module slots, labeled A and B. One
management module is required for switch operation; however, adding a second management module
increases system availability through redundancy. Each management module contains a temperature
sensor, nonvolatile random-access memory (NVRAM), and a real-time clock.

Redundant Management Module Activity
The BlackDiamond 20808 switch can operate with a single management module installed, providing full
bandwidth with this single management module. When you install a second management module, one
of the management modules operates as the primary, and the other becomes the secondary or backup.
The primary management module is responsible for upper-layer protocol processing and system
management functions. The management modules in the BlackDiamond 20808 switch are not load
sharing. One management module handles packets while the other is idle.
When you save the switch configuration, it is saved to all management modules.
Selection of the primary management module occurs automatically. The following examples describe
the selection process:
●When a BlackDiamond 20808 switch boots with two management modules installed, the
management module in slot A becomes the primary.
If a switch is operating with one management module and a second management module is added
to the switch after it has been powered up, the added management module becomes the secondary.
Management modules that operate as secondary, or backup, management modules can be inserted
and removed without disrupting network services.
●If you remove the primary management module while the switch is operating, the secondary
management module performs a soft reset and then becomes the primary management module.
For example, if you have a BlackDiamond 20808 switch with a primary management module in
slot A and a secondary management module in slot B, and you remove the primary management
module from slot A, the secondary, or backup, management module in slot B becomes the primary.
Features of the Management Module
Figure 3 shows the front panel of the BlackDiamond management module.

Management Modules
BlackDiamond 20808 Switch Hardware Installation Guide 19
Figure 3: BlackDiamond 20808 Management Module
Management modules have the following features on the front panel:
●Console port—The DB-9 serial console port is used to connect a terminal, allowing you to perform
local management.
●Management port—The 10/100 Mbps Ethernet management port allows you to connect an Ethernet
cable directly from your laptop to the management port to view and locally manage the switch
configurations. This port can also be used to connect the system to a parallel management network
for administration.
●Reset button—Use the Reset button to reset the management module without removing the module
from the chassis.
