I need to know if the VS-SUP2T-10G supports the WS-X6148-45AF linecard.

in the site:

it supports:

WS-X6148A-RJ-45, WS-X6148A-45AF, WS-X6148-FE-SFP, WS-X6148A-GE-TX, WS-X6148A-GE-45AF, WS-X6148E-GE-45AT

our line card is WS-X6148-45AF, what is the difference between WS-X6148-45AF and WS-X6148A-45AF?  Will the VS-SUP2T-10G support it?


"The Supervisor 2T provides backward compatibility  with the existing WS-X6700 Series Linecards (with the exception of the  WS-X6708-10G, which will be replaced by the new WS-X6908-10G, discussed  later), as well as select WS-X6100 Series Linecards only. There is no  support for the WS-X62xx, WS-X63xx, WS-X64xx, or WS-X65xx Linecards"


Here's the ones that are:

WS-X6148A-RJ-45   48-port 10/100/1000 RJ-45 (Upgradable to PoE 802.3af)

WS-X6148A-45AF    48-port 10/100 RJ-45 with PoE 802.3af

WS-X6148-FE-SFP   48-port 100 BASE-X (SFP)

WS-X6148A-GE-TX   48-port 10/100/1000 Ethernet RJ-45

WS-X6148A-GE-45AF 48-port 10/100/1000 Ethernet RJ-45 with PoE 802.3af

WS-X6148E-GE-AT   48-port 10/100/1000 RJ-45 with PoE 802.3af and PoE+ 802.3at
