RmtSERFHstLostFault
Major
Remote not 
receiving any 
messages from 
connected Host
There are two 
possible actions:
• Check  for  optics 
disconnect. Check 
the optical link 
and determine the 
source of lost 
communications. 
If an optical meter 
on the output of 
the SFP 
determines that 
no power is being 
transmitted, or 
meter measuring 
receive levels at 
the SFP 
determines the 
receiver is broken, 
replace SFP with 
the appropriate 
type for the range 
of signal 
supported.
• There  may  be  an 
IP conflict. For 
example, if the 
Host is configured 
in External 
Network mode but 
there's not a DHCP 
server running on 
the network, the 
Remote will not 
receive an IP 
address, there 
therefore will not 
be communication 
with the Host, 
which would 
activate this 
alarm.
RmtSERFOptLaserFault

RmtSERFOptOverDriveFault
Major
The power of the 
signal received at
