different rmware and must both be upgraded separately.
SIS Command Validity Table
If only one ber optic channel is enabled, the ability to congure
the system through SIS commands is limited by the lack of
return communication from the receiver to the transmitter.
All commands issued through the transmitter are valid because
link 1 allows signals to be forwarded to the receiver. However,
responses to queries originating from the transmitter about the
status of the receiver will return invalid data.
All conguration of the receiver by commands issued through
the receiver will be valid. Attempts to congure the the
transmitter through the receiver in the absence of link 2 will be
invalid.
The following table shows the validity of commands issued
through the receiver when only link 1 is active:
