B.7

Network Interfaces

Each I/O+ board has an onboard Ethernet circuit, connected to an RJ-45 twisted-pair
connector and a 40-pin media independent interface (MII) connector. The circuit
automatically adapts to 10 Mbit or 100 Mbit at the twisted-pair port. The 100 Mbit
MII connector accepts external Ethernet transceivers. If a transceiver is attached to
the MII connector, the twisted-pair connector is disabled.
Ethernet SBus interface cards may also be added to one or more I/O+ boards for
additional networks.
B.8

Internal Disk Drives

The 5-slot standalone Enterprise 3500 server has a capacity of eight internal FC-AL
disk drives. ID addresses are set automatically and are determined by disk bay
location.
B.9

Media (DVD-ROM/Tape Drive) Tray

The media tray at the front of the system accepts two SCSI devices, such as a
DVD-ROM drive and optional tape drive. The drives connect to the wide SCSI
connector of the first I/O+ board (in card cage slot 1). See Appendix C for SCSI ID
addressing.
B.10

Expansion Cabinets

The Enterprise 3500 system supports Fibre Channel and differential SCSI interface
disk storage options.
