Connector Specifications

This section provides pinouts for the following connectors:

•Ethernet—Table C-1

•Console—Table C-2

•Serial (basic)—Table C-3

•Power—Table C-4

Function 1 in Table C-1Table C-1 describes how the connector functions when the HUB/NO HUB button is in the HUB (in) position. Function 2 describes how the connector functions when the HUB/NO HUB button is in the NO HUB (out) position.
