Self Healing Ring (SHR) ID Setting
The Self Healing Ring (SHR) can be connected with a maximum of 128 units. The ID setting can be
configured with either hardware or software (each unit must have a unique ID). Hardware configuration
is limited to the default IP addresses. Therefore, it is generally used for bench testing.
Note:
Software configurations will overwrite the hardware settings for SHR ID and for Master/Slave (see
chapter 4 for software configurations). The reset button can be used to return the unit to the current hardware
settings.
Hardware SHR ID Settings
Dip switches 1-7 on the rear panel of the unit are used to configure the SHR ID's. They represent bit numbers,
#1, least significant and #7, most significant. The values(1, 2, 4, 8, 16, 32, and 64) for setting the SHR ID are
represented by the bit number exponent of 2 (see table 1 and figure 3). Also refer to Appendix B.
Chapter 3 - Hardware Configuration
Examples: To set the SHR ID
ID=1:
Set dip switch 1 to the down position and the rest to the up position.
ID=2:
Set dip switch 2 to the down position and the rest to the up position.
ID=3:
Set dip switches 1 and 2 to the down position and the rest to the up position.
ID=4:
Set dip switch 3 to down the position and the rest to the up position.
ID=5:
Set dip switches 1 and 3 to the down position and the rest to the up position.
ID=6:
Set dip switches 2 and 3 to the down position and the rest to the up position.
ID=7:
Set dip switches 1, 2 and 3 to the down position and the rest to the up position.
ID=8:
Set dip switch 4 to the down position and the rest to the up position.
ID=9 to 127:
Please refer to the SHR ID Setting Tables on Appendix B.
Dip switch 8:
The Slave/Master dip switch (each ring can only have 1 Master) is used to set the unit
as a Master or a Slave.
Master:
Set to down position.
Slave:
Set to up position.
Note:
The Master unit must be set to SHR ID = 0 (All SHR ID dip switches must be in the up position).
When using hardware configurations, the SHR ID = N will set the IP address to 192.168.254.[100+N].
For example, if the unit is set for SHR ID = 12, the IP address is 192.168.254.112.
