Ethernet Channels
The Shelf Manager Module provides two 10/100 Ethernet interfaces. The first Ethernet channel (ETH0) is
routed to the jumpers JP40 through JP43 and then to either the RJ-45 connector on the front panel or to the
backplane connector J2. The backplane routes this channel to the ShMC port on the corresponding Base
Interface Hub board. The second Ethernet channel (ETH1) is routed to the other Base Interface Hub board
(ShMC Cross Connect). Both Ethernet ports support 10 Mb (10BASE-T) and 100 Mb (100BASE-TX)
connections.
The Shelf Manager Module provides two status LEDs for each Ethernet channel (ETH0 and ETH1). The
LEDs are:
• Yellow LED indicates 100 Mb speed when lit.
• Green LED indicates link/activity when lit/blinking.
5 Blue LED on solid PEM is ready for hot-swap. PEM may be safely removed
from the chassis.
