The faceplate Ethernet port contains LED indicators incorporated into and RJ45 connector.
The Embedded Ethernet Switch directly controls the faceplate Ethernet port.

TLAN/ELAN LED color
yellow
green
When a link is establish, the green LED illuminates and flashes when activity exists on the link.
When the link is established at a 100 BaseT speed, the yellow LED illuminates, otherwise it
does not illuminate.
Network connections and dual homing
Each of the dual assembly boards of the MG XPEC contains 4 physical network connections.
The MG XPEC contains no physical network back plane connection as does the MGC. The
dual homing feature on the MGX works identically to the MGC, except all 4 network connection
are on the faceplate. Faceplate connections must be routed to the rear I/O using the new
NTDW25AAE6 cable kit. See
faceplate.
