Eagle 450 Installation and Technical Manual, Rev. 00
Chapter 3 - Configuration
This chapter discusses configuration rules, considerations, and procedures for the Eagle 450. It covers:
•
Back panel connectors
•
Wide and narrow SCSI configuration
•
Serial and parallel I/O, including cabling information
•
Networking
•
UPS status port
THE EAGLE 450 BACK PANEL
The illustration on the next page shows the Eagle 450 back panel, with the usable connectors labeled.
Refer to that drawing for the location of these connections:
•
Each serial I/O expansion slot will accept an AM-90 board, which provides four RJ-45
connectors (standard for the eight on-board serial ports and the AM-318-10), an RJ-21 Telco
connector from an AM-318-00, or, with an adapter, two DB-9 connectors from an AM-314. If
you choose to use DB-9 connectors for compatibility with earlier hardware, your total port
capacity is reduced, as only two ports fit in each slot instead of four.
•
You can use only one of the two Ethernet ports: either the RJ-45 10BaseT connection or the 15-
pin AUI connection. You cannot use both ports simultaneously to attach the Eagle 450 to two
networks.
•
The external SCSI connector may be either a Wide SCSI-2 68-pin or a SCSI-2 50-pin connector,
depending on the SCSI bus you’ve chosen.
•
The two PCI connectors are covered in the initial versions of the Eagle 450. Support for PCI
devices is planned for a future release.
These notes refer only to the types of connections you may see on the back panel; for more information
on SCSI, serial, and parallel I/O, and network connections, please refer to the appropriate sections later
in this chapter.
This back panel is used for factory-shipped Eagle 450s. Systems field-upgraded to an Eagle 450
have a different back panel, as shown in PDI-03500-21,
Upgrade Instructions, AM-1600 or
