Technical data

The TLZ04 tape drive uses a SCSI bus node ID plug to identify the drive’s
node number to the system. Spare bus node ID plugs are supplies with
your system and expander. SCSI plugs are light gray (PN 12-28766-28).
To insert a bus node ID plug, align the two center prongs with the two
center slots on the drive front panel as shown in Figure 2–9. To remove a
bus node ID plug, grasp it firmly and pull it straight out.
Use the rules below for numbering selecting an appropriate SCSI bus node
ID for the TLZ04:
• For each SCSI bus or KZQSA adapter, do not duplicate bus node
numbers. If you are installing multiple TLZ04 or RZ-series ISEs, the
SCSI bus node ID for each SCSI device must be unique.
• By convention, the devices are numbered in increasing order from right
to left starting with 0, and working from upper mass storage area to
lower.
Bus nodes 0–6 are typically used for storage devices, while node 7 is
reserved for the SCSI adapter and is the default bus node ID for the KZQSA
adapter.
NOTE: If you change the bus node ID plugs while the system is operating,
you must turn off the system and then turn it back on for the new plug
positions to take effect.
2.6 Installing RF- and RZ-Series ISEs
RF- and RZ-series ISEs are installed thesameway. The RF-series ISE has a
small flat cable which connects between the front panel and the CPU and a
bus ID plug. The RZ-series ISE front panel has only an ID plug connected
to it. No other controls or indicators are present on the RZ-series front
panel. The RZ-series ISE is shown in Figure 2–10.
When installing ISEs, you should first fill all of the available mass storage
compartments in the system enclosure first then install other ISEs into the
expander (if applicable).
CAUTION: Static electricity can damage integrated circuits. Use the wrist
strap and antistatic mat found in the Antistatic Kit (29–26246–00) when
you work with the internal parts of a computer system.
Handle RF-series ISEs with care. Dropping orbumping the ISE can damage
the disk surface.
