C9500-24Y4C and SFP-10G-T-X Hardware Limitation

[vinniej]

With the latest version of IOS (IOS XE Cupertino 17.8.x) there is an "installation restriction for SFP-10G-T-X module on C9500-24Y4C and C9500-48Y4C— Only eight SFP-10G-T-X modules are supported at a time."  Is this a limitation that may be overcome by IOS or am I searching for an alternate module solution?

SFP-10G-T optics require huge amount of power to operate and this is the limiting factor.

Seems like a hardware limitation. I guess it could be that because the 9500 is mainly a core switch and most uplink ports from the access and anything northbound will use fiber, and if you need a few copper connections 8 should be enough.

Installation restriction for SFP-10G-T-X module on C9500-24Y4C and C9500-48Y4C— Only eight SFP-10G-T-X modules are supported at a time. If you insert a ninth SFP-10G-T-X module in a lower numbered port than the existing active eight SFP-10G-T-X module, a reload will bring up the ninth transceiver and moves the last existing port with SFP-10G-T-X module to error disabled state. This happens due to the order of sequence ports link bring up where the lower numbered port brings up the link first. This limitation applies in standalone and in Cisco StackWise Virtual setup with two C9500-24Y4C or C9500-48Y4C switches. Each switch can have eight SFP-10G-T-X modules.
