Table A–4 explains the nomenclature used in the cabling diagrams.

Table A–4 Cabling Diagram Key

T and B

R and L

Represent the top and bottom, right and left DSSI connectors in the

rear of the magazine tape subsystems and SF7x storage enclosures.

TFx

SFx

TF is the designation for a magazine tape subsystem.

SF is the designation for a SF7x storage enclosure.

Px Refers to the port number on the DSSI I/O panel.

Cables Three DSSI cables are used:

BC21Q–3F = 42-inch (unit to unit)

BC21R–5L = 70-inch (Sx300 I/O panel to unit)

BC21Q–09 = 108-inch (Sx300 to system)

T T at a DSSI connector stands for a DSSI terminator

(12–31281–01).

There are only four magazine tape subsystems per Sx300 storage array.

There are up to six SF7X storage enclosures per Sx300 storage array.

Table A–5 lists the diagrams in this appendix.
