17.2 Setting up Multiple Chassis
17.3 Chassis Dipswitch
For multi-chassis installations each chassis will need to be assigned a unique chassis ID.
➢ The COM400 chassis has a default setting as chassis one.
➢ Chassis identification is configured via a dipswitch on the backplane circuit board.
➢ To access the switch, you will need to remove the access door on the top panel of the COM400
chassis as shown below in Figure 8.
Figure 8 – COM400 Dipswitch Access Panel
Facing the back of the chassis the dipswitches are 1-4 from the right to the left as shown in Figure
9.
➢ Dipswitch numbers as shown in Figure 9 are added to the photo. They are not actually labeled.
Figure 9 - Chassis ID Dipswitch
➢ The default IP address of each COM51 card in a system is determined by the chassis ID and slot
number the card is installed in.
➢ The formula for determining this address is 192.168.3.[1 + (chassis ID X 16) + slot number].
Example for chassis one:
1 + (16*1) + 1 = 18 IP address of chassis one slot one is 192.168.3.18
