I ordered 2x MikroTik SFP+ module for regular twisted-pair LAN cables S+RJ10 tranceivers" from a uk supplier called wifi-stock.co.uk
https://www.wifi-stock.co.uk/details/MI ... sRJ10.html
I inserted 1x into a MikroTik CCR 1009 Router 10gb Port. RouterOS 6.48.1
I inserted 1x into a MikroTik CSS326-24G-2S+ Switch. SwOS 2.12.
I initially experienced many stability issues with these tranceivers, with the links flapping and re-negotiating between 2.5 to 5 to 10Gbps, up and down in several attempts.
I changed and tried several other CAT6 cables.
Eventually without explanation the flapping issues have disappeared.
Today I inspected my equipment, and planned to switch the tranceiver from Port 1 to Port 2 in the Switch, and the CCR 1009 Router from the 10Gbit port to the 1Gbit port. Just to test both the ports.
Whilst moving and handling the tranceiver in the MikroTik CSS326-24G-2S+ switch, upon touching the tranceiver I burnt my fingers. The surface temperature of these devices is EXCEPTIONALLY hot. I would say they are dangerous!
I note in the packaging that there is no such health warning about handling these. I assume these temperatures are not normal?
My colleague promptly logged in and checked the device status on both Router and Switch.
I was mortified to learn that one tranceiver is operating at 101oC in the Switch and 87oC in the Router. I believe this temperate is an unsafe operational temperature, and quite possibly a Fire risk. We also pointed an infrared thermometer gun at this tranceiver and the temperatures were consistant with those reported in the software.
The MikroTik operational temperature of these devices is 0 to 70oC. Both of the devices are operating outside of these parameters, and one in particular is dangerously high.
EDIT - I have now tested 2x 10GTek optical Transceivers. The temps are 31oC and 35oC respectively.
So what gives, are they faulty? Am I alone in finding these operating at insanely high temperatures? Something does not seem right.
