Fans
Up to four hot-swap internal fans cool the switch unit. Three fans are required for
normal operation. If an individual fan fails, the other fans continue to run, and the
switch unit continues to operate normally. You can replace a hot-swap fan module
while the switch is operating.
Fan operation and internal temperatures are monitored. If the air temperature
exceeds a threshold, the environmental monitor displays warning messages.
Note: If a fan module fails, the maximum operating temperature drops from 40°C to
35°C (104°F to 95°F).
The Service ( ! ) LED is lit if there is a failure of one or more fan modules. The
failed fan module LED (rear panel) flashes to indicate a failure.
AC power supply
The switch has two hot-swap ac power supplies, 550 W for Front-to-Rear or 750 W
for Rear-to-Front. Each internal power supply has an individual IEC 320 power
connector on the rear panel. The power cord attaches to a universal grounded ac
power source. You can replace a hot-swap power supply module without powering
off the switch or disrupting switch functions.
DANGER
Multiple power cords. This product might be equipped with multiple power
cords. To remove all hazardous voltages, disconnect all power cords. (L003)
