Ethernet Port Connector
The Ethernet Port connector is a standard RJ-45 receptacle that allows the
serial server to be connected to an Ethernet network. It also carries Power
over Ethernet (PoE) based on the IEEE 802.3af standard.
On the LPD401A two indicator LEDs are built into the RJ-45
connector.
Serial Port Connector
The Serial Port Connector is a DB-9 male connector (configured as a DTE)
supporting RS-232 serial communications including TD, RD, TRS, CTS,
DTR, DCD, DSR and GND signal lines. Use a standard serial cable if
connecting to a DCE; use a null modem (crossover) cable if connecting to a
DTE.
Refer to Appendices D, E and F for connection pin-outs.
Power Connector
Power is supplied to the LPD401A by PoE (Power over
Ethernet) via the RJ-45 Ethernet receptacle. Power over Ethernet may be
delivered via un-used pairs in the CAT-5 cable, or via a simplexed power
technique. Both options are supported by the LPD401A. PoE
power consumption for the LPD401A is rated Class 3.
Refer to Appendix E for Ethernet connection pin-outs and additional information
on PoE.
