3.3.3.3 Connecting GbE Interfaces to IP Network
The RTM-8410 provides two Gigabit Ethernet (GbE) interface ports (supporting 1+1
Ethernet redundancy). These ports are used for interfacing with the IP network (LAN). The
status of these ports are indicated by the
GBE LEDs on the 8410 blade on the chassis'
front panel (refer to ''LEDs'' on page 28 ). Depending on customer requirements, the
Ethernet ports can be provided as one of the following types:
„ 10/100/1000Base-TX RJ-45 connector interface (CAT-5 twisted-pair copper cabling)
„
1000Base-FX multi-mode optical small form-factor pluggable (SFP) transceiver, using
850 nm wavelength
Notes:
•
For Mediant 3000 HA, both RTM-8410's must be separately cabled to the
IP network (using the GbE interface ports). When in Simplex mode and
using two RTM-8410s (i.e., for 84 E1/T1), only the RTM-8410 in Slot 2
must be cabled to the IP network.
•
Two RTM-8410s are provided for 42 and 84 spans Simplex and HA
modes. Therefore, in an HA system and to provide full Ethernet
redundancy, it is recommended to connect all four Ethernet ports to the
external IP network. In addition, to provide Ethernet switch redundancy,
the two Ethernet ports on each RTM-8410 must be connected to different
switches.
•
When Mediant 3000 with 8410 blade is configured for Physical Network
Separation, the RTM-8410's GbE port is used only for interfacing with the
Media network. The connection to the Control and OAMP network
interfaces is performed on the PEM modules (refer to ''Connecting
Ethernet Interfaces to OAMP and Control IP Networks'' on page
57 ).
When Physical Network Separation is disabled, the RTM-8410's GbE
port is used for all traffic (i.e., Media, Control, and OAMP).
¾
To connect the GbE interfaces:
„ Connect the LAN cable to each of the RTM-8410's GbE ports, using Category 5 LAN
cables with RJ-45 connectors (refer to the figure below) or multi-mode fiber optic
cables with dual LC plugs.
