The book says configure terminal emulator as follows:
DEC-VT100
any baud rate 1200 - 115200
8 data bits, 1 stop bit, no parity
flow control = NONE
As far as cable goes, all I can find is reference to "cable supplied with switch".
It must be a standard cable, I would just try a strait thru, and if that doesn't work try a null modem.
