Installing a DECarray with a VAX 4000 System
D.1 Single-System Installation of a DECarray
c. Install the terminator or terminators (PN 12–31281–01) to their correct
position on the SF7x enclosures, TF857 magazine tape ISEs, and
system I/O panel (Appendix A).
Note that the positions are numbered on the cabinet frame side rails
on the front and the rear of the cabinet.
• If the array has an SF7x storage enclosure in position 1 ONLY then
install a terminator (PN 12–31281–01) in the left DSSI connector of
the enclosure.
• If the array has an SF7x storage enclosure in position 1 and a
TF857 magazine tape ISE in positions 5 and 6, then install a
terminator (PN 12–31281–01) in the bottom DSSI connector of the
TF857 magazine tape ISE in position 6.
• If the array has two TF857 magazine tape ISEs in positions 5 and
6, then install a terminator (PN 12–31281–01) in the bottom DSSI
connector of both TF857 magazine tape ISEs.
• If the array has an SF7x storage enclosure in position 1 only,
then install a terminator (PN 12–31281–01) in the leftmost DSSI
connector of position 1.
• If the array has an SF7x storage enclosure in position 1 and 2,
then install a terminator (PN 12–31281–01) in the leftmost DSSI
connectors of position 1 and 2.
• If the array has an SF7x storage enclosure in position 1, 2, 3, 4,
and 7, then install a terminator (PN 12–31281–01) in the leftmost
DSSI connectors of positions 4 and 7.
• If the array has an SF7x storage enclosure in position 1, 2, 3, 4, 7,
and 8, then install a terminator (PN 12–31281–01) in the leftmost
DSSI connectors of position 4 and 7.
3. Connect the ground strap (provided with the cable kit). Attach one end
of the strap according to the instructions found in the System Expansion
Installation Supplement. Connect the other end to one of the screws
securing the power controller to the storage array.
4. All other configurations, with or without TF857 magazine tape ISEs, do not
need terminators.
