Component LED Locations and Meanings
The Sun Fire X4800 server chassis has the capability for up to four 2000W hot-swap-capable, load-sharing power supplies. This configuration provides a 2+2 power redundancy. The server requires two power supplies to operate. The power supply fans assist in the cooling of the PCIe EMs and the NEMs. Airflow through power supplies is front-to-back. All four power supplies should be present for proper I/O cooling.
Each power supply has an LED panel that reports on its status and a locking lever that assists in the removal and installation of the component. If a power supply is not present, the front and back Service Action Required LEDs will light.
The AC power inlet connectors for the power supplies are located on the back side of the Subassembly module on the AC power block. When four power supplies are installed in the server (recommended configuration), the AC power must be supplied by two separate and distinct circuits.
Note - Power supplies are designated as customer-replaceable components (CRU).
