Input/Output Ports

vOne 25-pin parallel

vKeyboard

vMouse

vTwo Ultra3 SCSI (one to internal 4-pack disk drive backplane, one to external VHDCI mini 68-pin port)

vIntegrated Drive Electronics (IDE)

vTwo 10/100 Ethernet (IEEE 802.3 compliant)

vThree serial ports. Serial port 1 (S1) has two physical connectors, one RJ-48 located in front on the operator panel, and a 9-pin D-shell located on the rear of the chassis. The other two serial ports are 9-pin D-shell connectors and are located on the rear of the system chassis.

Current usage for the serial port connectors are as follows:

Serial Port	Location	Applicable Usage Examples
Number
Serial Port 1 (S1	Operator Panel	Service Agent, PDA System Management Applications
Front)		(for example: handheld devices, laptop sytems), Service
		Processor menus
Serial Port 1 (S1	Rear of the	Service Processor menus, Service Agent, PDA System
Rear)	System	Management Applications (interface cable required)
Serial Port 2 (S2)	Rear of the	Service Processor menus, HACMP
	System
Serial Port 3 (S3)	Rear of the	HACMP, UPS, and Modems
	System

Note: Serial port 1 is never used to run HACMP or UPS. If you are configuring your system to run HACMP and UPS concurrently, you must connect HACMP to serial port 2 and UPS to serial port 3. Do Not run UPS connected to serial port 2. If you decide to diconnect HACMP, you must reset the service processor reset pin-hole switch before running another application. The service processor reset pin-hole switch is located on the operator panel.
