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 110 V input voltages. When two identical power
supplies receive different input voltages, they can output different wattages, and trigger a mismatch.
ContentDirector NIC Indicators
Each NIC on the rear panel has two indicators that provide information on connection status and
speed. Refer to
NOTE: The indicator codes for NIC 0 and NIC 1 differ from the indicators codes for NIC 2 and NIC 3.
