2.2.1
Setting the Ethernet Jumpers
The Ethernet jumpers determine how your CSMIM-T1 operates on the
network. You can set the jumpers so that the CSMIM-T1 operates on
channel A, B, or C. Refer to Figure 2-1 to locate and configure the
jumpers.
There is a single jumper block, labelled J12, that is used to select both the
Ethernet Segment and the Subnet. Pin row A at J12 is used to select the
Subnet. Pin rows B and C are used to select Ethernet Channels. Please use
care in configuring the jumpers. Figure 2-1 shows the default settings
(Channel B) for the CSMIM-T1.
•
To operate on Channel A:
in pin rows B and C.
•
To operate on Channel B:
3 in pin row B, and the other jumper over the center pin and pin 1 in
pin row C.
•
To operate on Channel C:
1 in pin row B, and the other jumper over the center pin and pin 3 in
pin row C.
2.2.2
Setting the Subnet Jumper
The CSMIM-T1 allows grouping of the B and C channels into a subnet to
provide additional Ethernet networks. All MIMs in the MMAC to the left
of the CSMIM-T1 become isolated on the B and C channel FNB
connector. These additional networks cannot communicate over the B and
C channel FNB connector with any module to the right.
Ethernet Channel and Subnet jumper settings can be
NOTE
overridden by an EMME or EMM-E6 installed in the MMAC.
