BlackDiamond X8 Series Switches Hardware Installation Manual 9

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.
USB ports on the management module allow you to attach a single USB 2.0 flash drive. Only a USB
flash drive that is formatted using the file allocation table (FAT) file system is recognized on these
ports. Other devices, such as a USB external hard drive, will not be mounted.

Management Module
The switch has two dedicated management module slots, labeled A and B, for the BDX-MM1
management module. 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.
The Management Module has very high speed and scalable control plane support with an Intel i7 dual
core CPU which will run at 2 GHz, 1 GB compact flash and 2 GB ECC DDR3 SDRAM.
BlackDiamond X8 Series Modules and Fans
BlackDiamond X8 Series Switches Hardware Installation Manual 12

Redundant Management Module Activity
The switch can operate with a single management module installed or with two management modules
installed for redundancy.
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 management modules are solely
responsible for upper-layer protocol processing and system management functions and do not carry
data plane traffic between I/O slots.
When you save the switch configuration, it is saved to all installed management modules.
Selection of the primary management module occurs automatically. The following examples describe
the selection process:
•When a 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 becomes the primary management module.
For example, if you have a 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
Management modules have the following features on the front panel:
•Management1 port : The 10/100/1000BASE-T 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.
•Two USB ports: These ports allow you to attach a single external USB 2.0 flash drive for
downloading new software or rescuing an image. Only one of these ports can be used at any one
time. Only a USB flash drive that is formatted using the file allocation table (FAT) file system is
recognized on this port. Other devices, such as a USB external hard drive, will not be mounted.
•Console port : The RJ-45 serial console port is used to connect a terminal, allowing you to perform
local management.
•Auxiliary (AUX) port: For future development.
Management modules have the following LEDs (see LEDs on the BDX-MM1 Management Module):
•Presence of system errors (ERR)
•System environmental status (ENV)
•Master/backup status of the module (MSTR)
•General system status (SYS)

I/O Modules
The switch has the following I/O modules available:
•BDXA-10G48X
•BDXA-40G24X
•BDXA-40G12X
•BDXA-10G48T
No configuration information is stored on the I/O modules; all configuration information is stored on the
management modules.
When a 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 NVRAM.
You can configure parameters of an I/O module after it is installed, or 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.
See the ExtremeXOS Concepts Guide and the ExtremeXOS Command Reference Guide for feature-
specific information related to BlackDiamond X8 series modules.
BDXA-10G48X I/O Module
The BDXA-10G48X I/O module has 48 unpopulated SFP+-based 10-gigabit Ethernet ports.

Fabric Modules
Up to four fabric modules can be installed in each BlackDiamond X8 chassis to provide the active
switching fabric for the switch. The switch fabric supports N+1 redundancy. Three fabric modules are
required to provide full switch fabric capacity. The fourth module provides excess capacity but is not
required to maintain full line rate on the front-panel ports. Fabric modules are installed in dedicated
slots at the back of the chassis, behind the fan trays.
Figure 8: Fabric Module
1 = Inserter/extractor lever
Two types of fabric modules are available for the switch:
•BDXA-FM10T module
•BDXA-FM20T module
BlackDiamond X8 Series Modules and Fans
BlackDiamond X8 Series Switches Hardware Installation Manual 19

BDXA-FM10T fabric modules provide a total switch fabric capacity of 10 Terabits per second, and
BDXA-FM20T fabric modules provide 20 Terabits per second.
A switch fabric composed of BDXA-FM10T modules will provide full line rate for the BDXA-10G48X,
BDXA-10G48T, and BDXA-40G12X I/O modules. For the BDXA-40G24X I/O module, a BDXA-FM20T
switch fabric is required for full line rate on all ports. The BDXA-40G24X I/O module will not operate
with a switch fabric composed of BDXA-FM10T modules.
All the fabric modules in a switch must be the same type; you cannot combine BDXA-FM10T modules
and BDXA-FM20T modules.
Status LEDs for each fabric module are on the fan tray that is in front of that fabric module. The status
LEDs for the fabric module are labeled Diag and Stat.
The following table describes the meanings of the fabric module LEDs.

Fan Trays
At the back of the BlackDiamond X8 chassis are five vertical fan trays, each holding six fans. Fan trays
are hot-swappable. Two pairs of LEDs on each fan tray indicate operating status for the fabric module
installed behind that fan tray (LEDs for the BlackDiamond X8 Series Fabric Modules) and for the fan
tray (LEDs for the Fan Trays). Only the first four fan trays are associated with fabric modules.
Caution
Never lift the chassis by using the handles on the fan trays.
