I'm looking into adding either 5 port or 10 port 1GE Spa card into and existing 7604 with a SIP 400.
Is the 10 port card supported on the sip400 ?
Anyone know for sure?
10 GE SPA is not supported on SIP 400 see table 2 in:
5GE SPA it is
note that support is removed even from SIP 600 after 12.2(33)SXH:
Note3—Supported in 12.2SXF. Support removed in 12.2(33)SXH.
Hope to help
