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.
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 User Guide
for more information regarding the use of the compact flash memory card.
The 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
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
•
Two dedicated MSM slots, labeled 3/A and 4/B
Note
On systems running EXOS 15.x, slot 4/B can accommodate either an 8800-MSM48c, an
8800 e-Series I/O module, or an 8800 c-Series I/O module. On all other EXOS versions,
slot 4/B can accommodate an MSM only.
•
Power supply bay that accommodates up to six power supplies, accessed from the front of the
chassis
•
One fan tray, accessed from the front right of the chassis
•
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.
