Replacing the R-Packs
If you need to put the R-packs back in the tape drive, make
sure that pin 1 of each R-pack is aligned with pin 1 of the
socket and that no pins are bent. As shown in Figure 3, the
writing on the R-pack should face upward. Pin 1 of the
R-pack is marked with a colored line or dot and should line
up with the right side of the socket.
CAUTION
If you replace an R-pack, be sure to use the correct
type to avoid damaging the tape drive. Use an
8-pin, 6-resistor SIP terminator, rated at 220/330
ohms. Exabyte recommends either of the following
terminators (or equivalent):

: part number CSC 08A-05-221/331J
■
Beckman Industrial™: part number
L08-5C221/331J
Termination for a Differential tape drive
The differential tape drive does not include internal
terminators. If a differential tape drive terminates the SCSI
bus, it must be terminated externally. See page 7 for
information about the recommended terminator.
