Stack-T3 vs Stack-T3A

[ckuwajima]

In a mixed 9300L/9300LM stack, is Stack-T3A cable compatible with C9300L-STACK-KIT connector?

Conversely, is Stack-T3 cable compatible with C9300L-STACK-KIT2 connector?

For 9300 fixed uplink models, stack kit is mandatory for StackWise-320 and has to be ordered separately. Each stack kit consists of two stack adapters and one data stack cable.

It appears to be compatible. See table-2 in this link:

I read that guide. Should be compatible...but looking at the rear panel drawings shown in Cisco Catalyst 9300 Series Switches Hardware Installation Guide - Product Overview [Cisco Catalyst 9300 Series Switches] - Cisco, the StackWise-320 ports looks different in 9300L (figure 11) and 9300LM (figure 12).

I received an 9300LM and can say that the connectors are mechanically incompatible.

 Stack-T3A cable will NOT plug into C9300L-STACK-KIT adapter port, and STACK-T3 cable will not plug into C9300L-STACK-KIT2 adapter port.
