8.1 Firmware Replacement
The RLS utilizes a main microprocessor (called the Executive) and several smaller
satellite microprocessors that are found in some Field Replaceable Units (FRUs).
Each microprocessor (aka processor) needs its own firmware to function and that
firmware is stored in Flash memory dedicated to each microprocessor.
There is only one firmware set for the entire RLS and it is the Executive firmware
(700118). This set contains the firmware sets for all satellite processors within the
RLS except for the Q-Link Web Interface and the Fibre Channel bridge. The Execu-
tive firmware does not contain any firmware for the Tape Drives.
It's the Executive processors task to check the revision and integrity of each satellite
processor's firmware whenever RLS power is applied. If the Executive processor has
just been revised (as described above), it will then immediately revise any satellite
processor's firmware that is outdated. Changing a FRU may also cause the Executive
processor to update the firmware in the new FRU. It's conceivable that installing a
FRU that is newer than the Executive firmware may require updating the Executive
firmware.
If the Executive processor is functioning, its firmware may be uploaded through the
Medium changer's interface (SCSI or optional Fibre Channel), the Q-Conn RS-232 in-
terface (using XMODEM file transfer) or the Q-Link Web Interface. The Q-Link Web
Interface firmware can only be uploaded through its LAN or Internet connection.
Firmware should only be updated after consulting with Qualstar's Technical Support De-
partment. They can be reached at (805) 583-7744 or E-mail them at sup-
port@qualstar.com
8.2 Determining the Current Firmware Revision
The current Executive firmware part number and revision can be determined by
viewing the Display Revision status screen under the Maintenance menu. Follow the
steps in Table 8-1.
