¾ To connect the Gigabit Ethernet interfaces:
Connect the LAN cable (wired according to the pinouts described in the table below) to
one of RTM-6310 GbE ports, using one of the following cable setups (depending on
customer order):
• SPF transceivers: Multi-mode fiber optic cables with dual LC plugs.
• RJ-45 connectors: Category 5 LAN cables with RJ-45 plugs (refer to the figure
below):

To provide full Ethernet redundancy in a Mediant 3000 High Availability system, it is
recommended to connect all four Ethernet interfaces (two on RTM-6310 and two on RTM-
6310 Redundant) to the external IP network. In addition, to provide Ethernet switch
redundancy the two Ethernet ports on each RTM must be connected to different switches,
as illustrated in the figure below:
