Gigabit Media Converter Switch Installation & User Guide
20
The front side of the unit has two twisted-pair 10/100/1000Mb switch ports and
one 10, 100 or 1000Mb fiber port. Both the RJ-45 ports of the LBH2001A Series
Converter switches support auto cross (MDIX) operation performing the autocross
function under auto-negotiation mode only. The LBH2001A models are factory
configured at Full Duplex.
Two sets of LEDs indicating the operating status of ports are mounted on the
top and front (for extra viewing advantage while rack-mounted). For each port, there are
Link and Activity (LK/ACT) LED’s on the top indicating that the media cables are
connected correctly and showing, by blinking, when there is traffic. The LK/ACT
LED’s are repeated on the front as LA1 (port 1), LA2 (port 2), and LA3 (port 3). There is
a power (PWR) indicator on the front of the unit to validate that the unit is turned ON.
The single fiber port on the LBH2001A is multi-mode with an SC connector
or small form-factor connector (LC single-mode).
The external DC power plug connector and/or “jack” and the internal DC
input terminal is provided on the rear of the unit.
