8.7.2 Chassis Intrusion

The BMC monitors the chassis intrusion switch by polling the ADM1026 device. The cable from

the chassis cover is connected through the 2-pin header below. To disable chassis intrusion

detection, short the 2-pin header with a jumper.

8.7.3 External SCSI Activity LED Input Signal Connector

A 4-pin header (labeled HDD LED at CN44) is provided on the Server Board to track SCSI drive

activity on the Hot Swap Back-plane. The following table details the pin-out of the header. This

allows two RAID controller cards to connect their disk activity cables to the front panel hard disk

LED activity light. Note that IDE hard disk activity LED is not enabled on the SDS2 board via the

front panel connector at CN37. Pins 2 and 3 are tied together routed through an AND gate to Pin

9 of CN37 front panel connector.
