Power SMB (I2C) Connector
The Power System Management Bus (I2C) header (JPI2C) is used to moni- tor the power supply, fan and system temperatures. See the table on the right for pin definitions.
IPMB I2C
A System Management Bus header for the IPMI slot is located at IPMB. Connect the appropriate cable here to use the IPMB I2C connection on your system.
UID Buttons
There are two Unit Identification (UID) buttons on the serverboard. The Front Panel UID Switch connects to pin 13 of JF1. The Rear UID Switch (SW1) is located next to LAN2. Pushing the UID switch on the Front Control Panel will illuminate both the Rear UID and the Control Panel UID indicators. Push the either switch again to turn off both in- dicators. These UID indica- tors provide easy identification of a system that may be in need of service.
LAN1/2 (Ethernet Ports)
Two Ethernet ports (designated LAN1 and LAN2) are located beside the VGA port on the I/O backplane. These ports accept RJ45 type cables.
