've deployed 4- 9300's in two stacks.
All 4 switches are
C9300-48P Ver 16.9.2
Stack 1: SW2- SW3 (no issues)
Stack 2: SW4- SW5 (VoIP POE issues)
The second stack of two has number of Cisco VoIP phones that will not negotiate for power (about 10). when I do a 'sh power inline' command the port shows as 'auto' and 'off'
SW4#sh power in
Module 1 Available 423.0 Used 108.8 Remaining 314.2
Module 2 Available 491.0 Used 171.1 Remaining 319.9
This site was running as it is now with 3650's for the last few years.
When I remove the network connection from the CP8945 phone and plug it into the computer I have no trouble connecting to the network.
I did a cable diagnostics and got a strange result:
This test is with the connection plugged into a Cisco CP8945 VoIP Phone (phone not powered up)
SW4#show cable-diagnostics tdr interface Gi1/0/29
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi1/0/29 auto
Pair A 53 +/- 5 meters N/A Open
Pair B 55 +/- 5 meters N/A Open
Pair C 56 +/- 5 meters N/A Open
Pair D 54 +/- 5 meters N/A Open
This test is with same network connection plugged into a Dell PC
SW4#test cable-diagnostics tdr interface Gi1/0/29
SW4#show cable-diagnostics tdr interface Gi1/0/29
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi1/0/29 1000M
Pair A 59 +/- 10 meters Pair B Normal
Pair B 54 +/- 10 meters Pair A Normal
Pair C 59 +/- 10 meters Pair D Normal
Pair D 52 +/- 10 meters Pair C Normal
Right now, as a workaround if I move the connection from one port in SW4 to an open port it comes up no problem.
So confused. Any ideas would be welcome!
