2.3.2 Ethernet Fiber Optic Interface
The Ethernet fiber optic interface is realized using one Agilent HFBR-53A5VEM Fiber Optic
Transceiver for each Ethernet channel. These transceivers support full duplex 1000Base-SX
operation and are fitted with a duplex SC-type connector receptacle for interfacing to fiber optic
links. CON6 is implemented as Channel A when installed, and CON7 is implemented as Chan-
nel B when installed.
The following figure indicates the positioning of the transmit and receive receptacles and orien-
tation of the connectors and keying of the receptacles. The SC-type receptacle is designed to
support self-locking duplex SC-type male connectors. This ensures that the fiber optic links are
securely fastened to the receptacles.

2.3.3 PCI / PCI-X Interface
The PCI / PCI-X interface is CMC / PMC
compliant and is realized using three, 64-
contact, male connectors: CON2 (Pn3),
CON3 (Pn1), and CON4 (Pn2). The follow-
ing figure and tables provide pinout informa-
tion for this interface.
