C.1.9 Optional 4-mm and 8-mm Tape Drives
The system unit or server supports the optional 4-mm and 8-mm tape drives. Either
the 4-mm tape drive or the 8-mm tape drive may be installed in the system or server
unit in place of the CD_ROM drive.
C.1.9.1 4-mm Tape Drive
The 4-mm tape drive is equipped with a single-ended SCSI controller and a
1-MByte on-drive buffer. The 4-mm Tape Drive Specifications, document part number
802-5324, provides cleaning, jumper setting, and tape cartridge instructions for the
4-mm tape drive.
C.1.9.2 8-mm Tape Drive
The 8-mm tape drive is an enhanced 8-mm digital helical-scan cartridge tape
subsystem. It is packaged in the industry standard 5.25-inch (13.335-cm) half-height
form factor. The 8-mm Tape Drive Specifications, document part number 802-5775,
provides cleaning, jumper setting, and tape cartridge instructions for the 8-mm tape
drive.
C.1.10 Networking
The system unit or server supports 10-Mbit and 100-Mbit local area Ethernet IEEE
standard 802.3u (also known as 100BASE-T) through the FEPS ASIC. The
FastEthernet standard is backwards-compatible with the standard 10-Mbits per
second Ethernet standard. The speed is auto-sensed.
Twisted-pair Ethernet (TPE) support is provided through a RJ45 connector. In
addition, a media independent interface (MII) connection provides support to any
other form of Ethernet (AUI/TP/ThinNet). The MII connection is provided through
a 40-pin MII connector. MII converters include MII-to-AUI and MII-to-fiber optic.
Note – The MII-to-AUI converter connects the MII connector on the backpanel of
the Sun Ultra 2 series system unit or the SunFastEthernet™ adapter to AUI
10BASE-5 DB-15 Ethernet connectors. Contact your Sun representative to order an
MII-to-AUI converter, order X467A.
