Fan Assembly
The system fan assembly, located in the chassis, provides cooling air for the installed modules
(Figure 2-8). Sensors on the fan assembly and within the system monitor the internal air temperatures.
If the air temperature exceeds a preset threshold, the environmental monitor displays warning messages.
Figure 2-8 Fan Assembly
If an individual fan within the assembly fails, the FAN STATUS LED turns red. To replace a fan
assembly, see Removing and Replacing the Fan Assembly, page 9-12.
Power Supplies
The Cisco SCE8000 GBE platform supports redundant AC- or DC-input power supplies. The following
power supplies are available for the Cisco SCE8000 GBE platform:
• 2700 W DC input (PWR-2700-DC/4): uses an external terminal block on the back side of the chassis
for input power connection (Figure 2-10).
• 2700 W AC input (PWR-2700-AC/4): uses an external power cord directly connected to the AC
power supply (Figure 2-9).
