Setting the SRX Expansion Module Address Switches
Setting the SRX Expansion Module Address Switches
Each SRX expansion switch module has two internal rotary switches that are used to set the address for that unit.
Each unit in a switch matrix only responds to control commands prefaced with an address that corresponds to the
address set on the switches.
The address for a particular unit is pre-set at the factory and normally will never need to be changed. However, if a
particular unit is exchanged with another unit, the address for that unit may need to be changed. Figure 1 shows the
orientation of the switches. Table 1 defines the addresses that are typically associated with the various module IDs.
To access the switches, remove the two round black hole plugs on the top cover. The two switches are mounted
directly under these holes. Use a small screwdriver to change the switch setting. The arrow near the center of the switch
points to the current switch setting. The address is in hexadecimal notation and will be between 00h and FEh (where “h”
denotes hexadecimal). After the address has been changed, replace the hole plugs. Finish by replacing the old unit
address label with the new label that has been provided. Table 1 defines the addresses that are typically associated
with the various module IDs.
