Symcli command
Can be used to check the RX and TX powers (light levels) of the SFPs associated with the FA port.
This command reports the receive and transmit power levels in mW for FA ports on PowerMax arrays running PowerMaxOS 5978 Q1 21 SR and above.
Below are the FA port to SFP mappings for Front-End I/O Modules in a PowerMax 2000 and 8000 arrays:
IOM-2
Port 4 - SFP-0
Port 5 - SFP-1
Port 6 - SFP-2
Port 7 - SFP-3
IOM-3
Port 8 - SFP-0
Port 9 - SFP-1
Port 10 - SFP-2
Port 11 - SFP-3
IOM-8
Port 24 - SFP-0
Port 25 - SFP-1
Port 26 - SFP-2
Port 27 - SFP-3
IOM-9
Port 28 - SFP-0
Port 29 - SFP-1
Port 30 - SFP-2
Port 31 - SFP-3
Below are the OR ports to SFP mappings for the Fron-End I/O Modules in PowerMax 2500 and 8500
IOM-1
Port 0 - SFP-0
Port 1 - SFP-1
Port 2 - SFP-2
Port 3 - SFP-3
IOM-2
Port 4 - SFP-0
