Note
If the customer’s UPS does not provide a communication link between the
UPS and the autochanger/computer system, someone will have to shut
down the computer system before the UPS battery power is drained or
data in the buffer may be lost.
If the UPS is connected to the RW504/RW524 optical disk library, the power
requirements shown in Table 2–2 must be met:
Table 2–2 UPS Power Requirements
Volt-Amps Watts
125 Volt-Amps (typical) 75 Watts (typical)
180 Volt-Amps (maximum) 110 Watts (maximum)
CAUTION
Connecting the UPS to the autochanger incorrectly may not provide full
protection against data loss. To insure proper UPS connection, perform
the following steps:
• Use the proper cable when connecting a UPS to the autochanger.
• Run test 75 after connecting the UPS to the autochanger. (See
Section 4.9.2 for instructions for running test 75.)
2.7 Hardware Verification
The Customer Engineer (CE) needs to verify that the optical disk library is
fully functional. To do this, the CE powers up the unit, which will invoke the
poweron diagnostic. After completion of the poweron diagnostic, the CE needs
to execute internal diagnostic tests 2, and 11 through 17 (Section 4.10) and test
the autochanger mechanism and drive(s) to verify that all functions of the optical
library unit (moves, flips, reads, writes, and so forth) are operating correctly.
Refer to the appropriate Setup Guide and host configuration guide to complete
the installation.
