RJ-45 LAN Connector LEDs

Two LEDs are built into the RJ-45 LAN connector. Table 4 describes the LED states when the
board is powered up and the LAN subsystem is operating.

Battery

A battery on the server board keeps the values in CMOS RAM and the clock current when the
server is turned off. See Chapter 2 for instructions on how to replace the battery.

Power Management Features

Power management is implemented at several levels, including:
•
Software support:
 Advanced Power Management (APM)
 Advanced Configuration and Power Interface (ACPI)
•
Hardware support:
 Wake on LAN technology
 S5 wake on all PCI slots
 Wake on Ring
 Resume on Ring
If the board is used with an ACPI-aware operating system, the BIOS can provide ACPI support.
Otherwise, it defaults to APM support.

Wake on LAN Technology

The Wake on LAN technology connector can be used with PCI bus network adapters that have a
remote wake-up connector. Network adapters that are PCI 2.2 compliant assert the wake-up signal
using the PCI bus signal PME# (pin A19 on the PCI bus connectors). See Figure 21 on page 68 for
the location of the Wake on LAN technology connector on the server board.
CAUTION
For Wake on LAN technology, the 5 V standby line for the power supply must be capable of
providing adequate +5 V standby current. Failure to provide adequate standby current when
implementing Wake on LAN technology can damage the power supply.
