RackSwitch G8264T: Installation Guide
Reset button
The Reset button is recessed within a hole on the front panel. Use a straightened
paper clip or similar object to press the Reset button. The Reset button allows
technicians to reset the switch, as follows:
• Press
Reset : The switch resets and reloads the configuration files.
• Press and hold Reset for five seconds: The switch resets and configures all
settings to factory defaults.
Fans
Four hot-swap fan modules cool the switch unit. If an individual fan module 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 desired threshold, the environmental monitor displays warning
messages.
Note: If a fan fails, the maximum operating temperature drops from
+40ºC
to
+35ºC
(104ºF to 95ºF)
.
The Service ( ! ) LED flashes and the Fan LED flashes 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 G8264T has two hot-swap redundant 750W AC power supplies. 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.
(L001)
Each power supply can be connected to a separate AC circuit to mitigate the risk of
down time during a power failure. When used in a redundant configuration, the dual
power supplies have a load-sharing capability that allows each supply to operate at
approximately 50% of full load. Using redundant power can minimize the power
disruption during a power supply failure and extend the expected lifetime of each
supply by operating normally in a conservative power mode.
There is no power switch on the G8264T; the switch unit powers up when power is
supplied through the power cord(s). Power cords must be ordered separately.
DANGER
Hazardous voltage, current, or energy levels are present inside any
component that has this label attached. Do not open any cover or barrier
that contains this label.
