RS-232 Console Port Connector and Cable Pin-Outs
The hub’s console connector is wired as if it is a terminal (DTE), ready to be
connected to a modem (DCE). The HP AdvanceStack hubs include a null
modem cable that can be used to directly connect a PC to be used as the
console. To connect a modem to the hub, use a standard RS-232-C modem
cable.
This section provides pin assignment information for the cables you can use
on the hub’s RS-232 management console port.
