3.4 Replacing RF and RZ Series Integrated Storage
Elements (ISE)
NOTE: The illustrations in this section show the BA440 enclosure.
Duplicating the same basic illustrations for the BA430 enclosure is
unnecessary. The removal procedures are the same for both enclosures.
This section describes how to replace RF and RZ-series ISE’s. In addition,
procedures are provided to replace the following individual FRUs that
comprise the integrated storage element:
• ISE Bus I.D. plug
• ISE front panel
• ISE front panel module (RF-series only)
• Interface card assembly (RF-series only)
• Remote front panel cable (RF-series only)
For information on troubleshooting strategy, error analysis, and RZ and
RF-series diagnostics, as well as information on removal and replacement
of the drive module and head-disk assembly (HDA), refer to the appropriate
integrated storage element service guide. Replacing the drive module does
not require removal of the ISE bracketry.
