1.2.7 Connecting the GBE1/GBE2 trunk interface
The system provides two types of trunk interfaces (two ports for each type): electrical (RJ-45) and
optical (mini-GBIC) interfaces. When both electrical and optical ports are connected, system will
automatically select the interface according to the priority setting (Fiber first or Copper first).
RJ-45 Electrical Trunk Interface
The pin assignment of RJ-45 connector on the trunk port is shown in the following figure and
table.

Mini-GBIC (SFP) Trunk Interface
Prepare a proper SFP module and install it into the optical trunk port. Then you can connect fiber
optics cabling that uses LC connectors or SC connectors (with the use of an optional SC-to-LC
adapter) to the fiber optics connector on the trunk port.

Note
—
Please observe the proper connecting terminals for transmitting cable to TX LC-type
receptacle, and receiving cable to RX LC-type receptacle on the front panel.
Warning
—
Never look directly at the transmitting ports of optical interface that might
be emitting laser, in order to prevent damage to the eye from the laser radiation.
