Table 9–8: Power Supply Indicator Pattern
Indicator Pattern
Not lit AC power is not connected.
Green The handle indicator lights green indicating that a valid power source is connected to
the power supply and that the power supply is operational.
Flashing Amber Indicates a problem with the power supply.

Flashing Green When hot-adding a power supply, this indicates that the power supply is mismatched
with the other power supply (in terms of efficiency, feature set, health status, and
supported voltage). Replace the power supply that has the flashing indicator with a
power supply that matches the capacity of the other installed power supply.
ContentDirector NIC Indicators
Each NIC on the rear panel has an indicator that provides information on network activity and link

CAUTION: When correcting a power supply mismatch, replace only the power
supply with the flashing indicator. Swapping the opposite power supply to make a
matched pair can result in an error condition and unexpected system shutdown.
To change from a High Output configuration to a Low Output configuration or vice
versa, you must power down the system.
CAUTION: AC power supplies support both 220 V and 1 10 V input voltages.
When two identical power supplies receive different input voltages, they can
output different wattages, and trigger a mismatch.
CAUTION: If two power supplies are used, they must be of the same type and
have the same maximum output power.
A–7, and Table 9–9
detail the NIC indicators and the possible states of each.
