3.1.1 EF/RF-Series Integrated Storage Elements
Using the dual-disk RF, your system can have up to seven EF/RF-series ISEs or
up to six EF/RF-series ISEs and a tape drive. When your system has multiple
ISEs, you should separate them according to function. For example, if your
system has two ISEs, you may want to use them as follows.
• ISE 0 contains the operating system and applications installed on the system.
• ISE 1 contains work areas for each user with an account on the system.
The storage capacities and other specifications for EF/RF-series ISEs are listed in
your system
Technical Information
manual.
Note
Some RF ISEs have a dual-disk capability: Two separate ISEs can share
the same mass storage cavity and RF35 front panel.
Refer to Appendix B for information on setting or examining parameters
for DSSI devices.
3.1.1.1 EF/RF-Series Controls and Indicators
Each EF/RF-series ISE has controls (except RF35, RF31T, RF36) and indicators
on its front panel. To access them, open the upper system door (top key position).
Note
If your system has less than the maximum number of ISEs, a blank ISE
front panel with no controls or indicators covers the empty ISE cavities.
Such panels are required to meet international regulatory standards and
airflow requirements.
If your system has a 3.5-inch RF with only one disk, one set of controls
will have a blank bus node ID plug and its indicators will not light.
Each 5.25-inch EF/RF has the following controls and indicators on its front panel.
• Bus node ID plug
• Fault indicator
• Write-Protect button
