Parallel connector

There is one parallel connector on the rear of the computer. Use this connector to
connect a parallel device. The following illustration shows a parallel connector.
The parallel connector supports three standard Institute of Electrical and Electronics
Engineers (IEEE) 1284 modes of operation: standard parallel port (SPP), enhanced
parallel port (EPP), and extended capability port (ECP). If you configure the parallel
port to operate in bidirectional mode, it supports the ECP and EPP modes. When
the parallel connector is configured as bidirectional, use an IEEE 1284-compliant
cable that does not exceed 3 meters (9.8 ft). Use the Configuration/Setup Utility
program to configure the parallel connector as bidirectional.
Complete the following steps to view or configure the parallel connector:
1. Restart the computer.
2. Press and hold the F1 key to launch the Configuration/Setup Utility program.
3. On the Configuration/Setup Utility menu, use the cursor keys on the keyboard to
4. Follow the instructions on the screen to save your changes and exit from the

Serial connectors

There are two serial connectors on the rear of the computer. Use these connectors
to connect serial devices. The following illustration shows a serial connector.

Ultra320 SCSI connector

An optional external SCSI connector might be installed on the rear of the computer.
Use this connector to connect external SCSI devices. The following illustration
shows the SCSI standard 68-pin, female D-shell SCSI connector.
Your computer has an integrated SCSI controller with RAID capabilities. This
dual-channel controller supports two independent, Ultra320 SCSI channels. The
SCSI connectors for both channels are on the system board. Each channel
supports up to 15 SCSI devices. This controller uses:
v Double-transition clocking to achieve up to 320 MB-per-second data-transfer
v Domain name validation to negotiate compatible data-transfer speeds with each
v Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
v An active terminator for SCSI bus termination
