The Powered Chassis is intended to be used with two power supplies in a
power-redundant operation. A failure of a single supply should not disturb the
operation of the chassis unit. However, certain power supply failures may
cause a secondary failure to the associated fan and cause undesired
overheating of the chassis unit.
It is very strongly recommended that a replacement power supply unit be installed
as soon as possible in order to prevent overheating of the chassis unit.
THE POWER SUPPLIES ARE HOT-SWAPPABLE AND CAN BE REPLACED
WITHOUT SHUTTING THE NETWORK DOWN. HOWEVER, WHEN REMOVING AND
REPLACING A POWER SUPPLY UNIT, THE FOLLOWING STEPS MUST BE STRICTLY
FOLLOWED IN ORDER TO PREVENT SERIOUS INJURY OR DEATH, OR SERIOUS
DAMAGE TO YOUR EQUIPMENT.
Hot Removal of Power Supplies:
1. Determine which one is the faulty power supply by observing the LEDs in the
front left of the chassis: the top LED indicates the power status of the right
power supply (as observed from the front), the bottom LED indicates the power
status of the left power supply (as observed from the front).
Notice that LED being ON indicates that the power supply is operational. The
LED being OFF may indicate that the AC power is not applied, please verify
that your AC power source is providing power.
2. Once you determine that your AC plug is connected properly to an AC wall
outlet, and the power supply LED is still not ON, determine which is the failing
power supply unit and proceed to the next step.
3. Remove the AC power cord of the faulty power supply from the wall outlet.
4. Remove the AC power cord of the faulty power supply from the power supply
unit.
