TP Means Terminator Power, I.E. the drive will feed 5 volts to the SCSI
bus to power a terminator at the end of the cable. Usually the SCSI
controller will put power on the bus, but if you have a long SCSI chain
it would probably more appropriate to enable TP on the last drive just
before the terminator. There is usually another jumper labelled TE
(Terminator Enable) or are there may be sockets for single in-line
terminator (resistor) packs.
