Selecting the maintenance navigation tab shows buttons for counters by component, lets you
view the maintenance log, and lets you start automated, step-by-step maintenance procedures
for various components. These procedures also include automated tests as needed to help-
be sure the GC is ready when maintenance is complete. See the 8890 Maintaining Your GC
manual for more information.
