Troubleshooting
This chapter contains procedures a user can perform, before calling
Digital Customer Services, to verify that a problem exists in the SF72
storage enclosure.
Procedures to attempt recovery from a fault condition are also included
here. Before attempting recovery from a fault condition, record the fault
code shown on the SF72 storage enclosure operator control panel (OCP),
as described in Section 4.2.
4.1 Verifying a Hardware Problem
If your SF72 storage enclosure or an installed disk ISE is not operating
correctly, check the following items before calling Digital Customer
Services:
WARNING
Hazardous voltages are inside the equipment cabinet and
the SF72 storage enclosure. Installation and service must be
performed only by qualified Digital Customer Services engineers.
When performing any operation involving the source power,
verify that the enclosure ac power switch, located on the power
supply at the rear of the enclosure, is turned off. Disconnect the
line cord from the enclosure rear panel and from the cabinet
power controller, if possible. Perform the operation, then
reconnect the cord.
1. If the entire SF72 storage enclosure is not operating, check the power
supply fault indicator. This indicator is visible, when lit, through
holes in the lower right corner of the SF72 storage enclosure. (Refer
to Figure 4–1).
