Re: HI experts , i have ICX 7450 switch and i am getting error as Latched low RX Power warning on switch interface

Hey Pradeep,

SFPs have the capability of monitoring a number of internal physical parameters that inform about the status of the device and the light link.
SFPs have the capability of monitoring a number of internal physical parameters that inform about the status of the device and the light link. The command "show optic" shows the different values as measured real time at the SFP.
These values are compared against an internal alarm setting as set by the manufacturer, and in case the warning or alarm limits are reached, an alarm flag will be set.
When optical monitoring is enabled in the device, the router will periodically monitor these flags, and when there is an issue, it will be reported in the Syslog.

Sometimes it can also be due to dust on the cables/patch panel.

-Are you having any connectivity problems due to this message?
-How long has it been in service?
-Can you paste output of "skip","show interface eth 1/1/6" (3 times 20 seconds apart) "show log", "show version", "show media", "page".

HI sir,
thanks for reply,
Connectivity from brocade to that access switch is ok, today again i took sh optic eth1/1/6

as per yesterday's log Rx Power value was NA, and today it showing something
it become confusing to what to check

should i change the both ends OFC patch cord ?
should i change SFP module ?
or anything else to do.

i have also captured access switch up-link port state as below
