1.3.2. Ethernet Ports
1.3.2.1. Ethernet User Ports
The two Ethernet user ports (Ethernet ports 1 and 3) provide 10/100BaseT
interfaces with standard RJ-45 pinouts. When the IDU is properly configured, the
IDU provides transport of Ethernet frames ingressed at these ports over the link to
the far side radio. An internal Ethernet switch also provides layer 2 switching
functions between these two ports and the far side terminal. The Ethernet PHYs
provide MDI/MDIX cross-connect with auto-detect, so both straight-thru and cross
cables are accommodated to any other 10/100 Base-T interface. Ethernet transport
is configurable to up to 170 Mbps.

1.3.2.2. Ethernet Management Ports
The two Ethernet management ports (Management port 0 and 2) provide
10/100BaseT interfaces to the IDU with standard RJ-45 pinouts. These ports allow
management access to the IDU’s internal CPU. An internal Ethernet switch also
provides layer 2 switching functions between these two ports and the far side
terminal. The Ethernet PHYs provide MDI/MDIX cross-connect with auto-detect, so
both straight-thru and cross cables are accommodated to any other 10/100 Base-T
interface.
1.3.2.3. Ethernet Port Front Panel LEDS
Two front panel connector LEDs are included for each of the four Ethernet ports.
Status of each is indicated in Table 7.
LED Indication Description
Left SPEED LED on indicates
100BaseT. LED off
(accompanied by LINK
LED on) indicates
10BaseT.
Right LINK/ACT LED on indicates link is
active. Blinking indicates
link activity (Tx or Rx).
