11.4.2.3 Cage Suggested Action 1
Check the connection/path to the SFP in the cage and the level of signal the SFP is receiving. An
RX Power reading below 100 uW will signal the RX Power Low condition; typical readings are
between 300 and 400 uW. Helpful CLI commands are
showcage -d and showcage -sfp
ddm
.
At least two connections are expected for drive cages and this exception will be flagged if that
is not the case.
