•192 ports of 40GbE QSFP+ per switch, 576 ports per rack
•32 ports of 100GbE CFP2 per switch, 96 ports per rack
Features of the ExtremeSwitching X8 Series (Formerly
BlackDiamond X Series) Chassis
The ExtremeSwitching X8 Series chassis has the following physical features:
•Height of 14.5 RU, allowing three switches to be installed in a 7-foot tall, standard 19-inch rack
•Optional mid-mount brackets for flexibility in rack positioning
•Horizontal front slots for I/O modules and management modules
•Eight full-width slots for IO modules
•Two half-width slots for management modules (MMs)
•Four vertical slots in the back (behind fan trays) for fabric modules (FMs)
•Eight bays in the front for redundant power supplies; rear-accessible power connections
•Five vertical fan trays at the back
•Two connectors for an ESD-preventive wrist strap
•On the front panel between the management modules

Management Module Ports
Each management module has a 10/100/1000BASE-TX Ethernet management port.
ExtremeSwitching X8 Series (Formerly BlackDiamond X Series) Switches
ExtremeSwitching X8 Series Switches Hardware Installation Guide for version 1.0 11

The management port enables direct communication with the central processing unit (CPU) of the
switch. IT personnel can plug an Ethernet cable directly from a laptop into the management port for
direct access into the switch. This access allows viewing and local management of 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.
For more information, including a diagram showing the location of the management module ports, see
Features of the Management Module on page 16.

Management Modules
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 reliability 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.
ExtremeSwitching X8 Series (Formerly BlackDiamond X Series) Modules and Fans
ExtremeSwitching X8 Series Switches Hardware Installation Guide for version 1.0 15

The following sections describe the functions and features of the ExtremeSwitching X8 Series (formerly
BlackDiamond X Series) management modules:
•Redundant Management Module Activity on page 16
•Features of the Management Module on page 16
•Management Module LEDs on page 17
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 trac 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 operating in secondary, or backup, mode 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.
ExtremeSwitching X8 Series (Formerly BlackDiamond X Series) Modules and Fans
ExtremeSwitching X8 Series Switches Hardware Installation Guide for version 1.0 16

•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 Management Module LEDs on page 17 for a
description of the LEDs and their meanings):
•Presence of system errors (ERR)
•System environmental status (ENV)
•Master/backup status of the module (MSTR)
•General system status (SYS)
•General fan status (FAN)
•Fabric module status (FM)

I/O Modules
The following I/O modules are available for use with your ExtremeSwitching X8 Series (formerly
BlackDiamond X Series) switch:
•BDXA-G48T
•BDXA-G48X
•BDXA-10G48X
•BDXA-10G48T
•BDXA-40G12X
•BDXB-40G12X-XL
•BDXA-40G24X
•BDXB-100G4X
•BDXB-100G4X-XL
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.
ExtremeSwitching X8 Series (Formerly BlackDiamond X Series) Modules and Fans
ExtremeSwitching X8 Series Switches Hardware Installation Guide for version 1.0 18

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.
Caution
If you preconfigure the I/O module type for a slot and then insert a dierent type of I/O
module into that slot, ExtremeXOS will detect a mismatch and will not power on the module
or generate any kind of default configuration.
See the ExtremeXOS 16.2 User Guide and the ExtremeXOS 16.2 Command Reference Guide for feature-
specific information related to ExtremeSwitching X8 Series modules.
BDXA-G48T I/O Module
The BDXA-G48T I/O module has 48 1Gb copper Ethernet ports.
Note
ExtremeSwitching X8 Series I/O modules are supplied with no pre-installed optical modules.
