Intel® Server System R2000LH2/T2 Product Family TPS Front Panel
Revision 1.0

11. Front Panel
The common front panel feature set conforms to the industry standard SSI 2x12 connector
specification, but includes an extension to this connector to support 3
rd
and 4
th
NIC Activity
LEDs. The longer connector is a 2x15 right angle header, which includes missing pin locations
at pins 25 & 26.
Figure 75. SSI Common Front Panel Board
While the front panel board uses a custom 2x15 connector, the baseboard simply adds a 2x2
connector in-line (and appropriately spaced) with the existing SSI 2x12 connector. Boards that
support Quad LAN can populate the 2x2 connector, and boards that only support Dual LAN can
depopulate the connector.
