5.2.3 Connecting GbE Interfaces to IP Network
The RTM-6310 (and RTM-6310 Redundant for HA mode) provide two GbE interface ports
(labeled ETHERNET 1 and 2) with full-duplex mode and auto-negotiation. These two ports
provide 1+1 Ethernet redundancy.
The Ethernet ports can be provided in one of the following types (customer ordered):
10/100/1000Base-TX RJ-45 connector interface (CAT-5 twisted-pair copper cabling)
1000Base-SX 1.25 Gbps multi-mode optical small form-factor pluggable (SFP)
transceiver, using 850 nm wavelength (hot-swappable)
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 (see the figure
below):
