BlackDiamond 10808 Switch
The BlackDiamond 10808 switch includes the following components:
●
One 10-slot chassis with backplane
●
Eight I/O module slots, labeled 1 through 8
●
Two MSM slots, labeled A and B
●
Up to six power supplies, accessed from the front of the unit)
●
Two fan trays, accessed from the back of the unit. Each fan tray contains two fans.
●
One connector for an ESD-preventive wrist strap
Software monitors the fan trays in the BlackDiamond 10808 switch for overheating. All over-
temperature events cause the switch to send alerts to the network management station or to the switch
log. See the
ExtremeXOS 12.0 Concepts Guide for more information about switch monitoring. The
BlackDiamond 10808 switch fan tray is hot-swappable.
CAUTION
Do not cover or obstruct the fan ventilation holes at the rear of the unit. Doing so can result in overheating and
possible damage to the BlackDiamond 10808 switch. Thermal sensors will shut down the BlackDiamond 10808
switch if the internal temperature exceeds 60 degrees Celsius.
The BlackDiamond 10808 switch includes two power supply controllers, located in the back of the
chassis, that collect data from the installed power supplies and report the results to the MSM modules.
The power supply controllers provide primary/backup redundancy in case one of the controllers fails
or is removed. At least one power supply controller must be installed.
When the BlackDiamond 10808 switch is first powered on, the power supply controllers enable the
power supplies by providing 48V power. The power supply controller also detects and reports
incompatible combinations of power supply types and line voltage feeds and disables the power supply
if an unsafe condition arises.

I/O modules.
