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.
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 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.1.7 Networking
The system unit or server supports 10-Mbit per second and 100-Mbit per second
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-Mbit per second Ethernet standard. The speed is
auto-sensed.
Category 5-type twisted-pair Ethernet 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/Fiber). The MII connection is provided
through a 40-pin MII connector. MII converters include MII-to-AUI and MII-to-fiber
optic.
C.1.8 Terminal, Modem, Keyboard, and Mouse
Connectivity
Terminal, modem, keyboard, and mouse connectivity is traditional Sunness
connectivity. Two serial ports provide synchronous and asynchronous
communication. The synchronous port supports data throughput rates up to 64
Kbaud. The asynchronous port supports data throughput rates up to 76.8 Kbaud.
Both RS-232 and RS-423 interface standards are supported. RS-232 or RS-423
interface selection is provided through a jumper setting. Default configuration is RS-
423. Two DB25 connectors are provided for the two serial ports.
