GE A8950CC - Manual (Page 13)

Overview
The Phoenix A8911ETH Ethernet module provides Ethernet connectivity to the Phoenix
system. Each module has three RJ-45 ports supporting full-duplex 10/100Base-T interfaces.
Each port also supports Auto-Negotiation and automatic MDI/MDI-X selection.
Unlike other modules used in the Phoenix system, the ethernet module does not use “chan-
nels”. Each slot position provides access to one of four independent Ethernet
networks. Every port on a module can communicate with every other port on other
modules connected to the same network (i.e. modules plugged into the same slot number
at different nodes). There is no restriction to the number of modules connected to a
network, however they must share bandwidth between nodes. Each network can sustain
25Mbps throughput between nodes.
Note: Ethernet is inherently a bi-directional communication protocol. Therefore all nodes in
a Phoenix system with Ethernet modules must be connected with duplex fiber connections.
Simplex connections between nodes will cause the network to fail.
Tools and materials required
The Ethernet modules are held in place with simple thumbscrews with screwdriver slots.
The only tool recommended is a small flat blade screwdriver.
Installation instructions:
1. Install the Ethernet module:
Up to four Ethernet modules can be installed in the Phoenix node. From left, locate and
insert Ethernet modules into slot 1, 2, 3, or 4 (color-keyed red) and secure.
