BX 4000 Sereies Quick Start Guide

Gateway Port Groups

The BridgeX gateway supports either Ethernet or InfiniBand on the uplink side, and Ethernet or FC on the
downlink side. On the downlink side all gateway port groups support a single protocol.

Uplink Ports

There are two uplink ports, one per gateway group.These ports have CX4 4x connectors. These connectors
have support for powered cables and media adapter circuits. The BX 4010B gateways have two uplink ports.
The uplink ports are labelled alpha-numerically and also the diagrams in this manual are color coded to their
corresponding downlink ports. For IB uplinks use the single specified port for each gateway port group.
B20, A20.

Downlink Ports

There are four downlink ports per gateway port group. These ports have SFP+ connectors that support both
direct-attach copper cable and optical cables by using a SR or LR modules. The downlink ports are labelled
alpha-numerically and the diagrams in this manual are color coded to their corresponding uplink ports. The
downlink ports must all have the same protocol. When the downlink is Ethernet use ports A10-12, B10-12.
When the uplink is IB and the downlink is FC all four of the connectors can be used.

Making Connections to Other Formats

Hybrid CX4 to QSFP cables are supported on both the uplink side and the downlink side. SR and LR mod-
ules can be used on the downlink side.
CX4 connectors are supported on the uplink side.
