About the BlackDiamond 8800 Series Switches

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 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. 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.
