Configuring SH043 Storage-Only Cabinets
This chapter describes the configuration of the SH043 storage-only cabinet. This
storage subsystem uses only the StorageWorks SHDZZ–ZZ shelf type. The Small
Computer Systems Interface 2 (SCSI–2) interface is used as the communications
path between the cabinet’s storage devices and their external controllers. SH043
storage-only cabinets can be configured with up to 10 storage shelves.
WARNING
While working in the cabinet interior, ac power must be removed from
cabinet components. Failure to do so may result in personnel injury as a
result of electric shock.
Prior to performing any of the procedures in this chapter, remove ac power from
the cabinet components. If the cabinet is installed and operating, spin down all
disk drives and halt all tape drives in the cabinet. Switch the circuit breaker on
the front panel of the cabinet’s cable distribution units (CDUs) to the
(OFF)
position.
4.1 Cabinet Configuration
WARNING
Failure to install cabinet components in the proper order could result in
cabinet instability, injury to personnel, and damage to equipment.
Note
To maintain FCC compliance and proper airflow, filler panels and air
separation panels must be installed as specified for your particular
cabinet configuration. See Section 4.2 for further information.
The order of shelf installation in SH043 storage-only cabinets is predetermined to
allow for cabinet loading and cable length factors. Figures 4–1 and 4–2 show the
layout of both the front and rear of the storage-only cabinet. To prevent cabinet
instability, shelves must be installed in the order shown by the position numbers
in the illustrations.
