This Chapter covers the maintenance procedures for VTrak.
The power supplies, cooling unit fans and the cache battery are hot-swappable
field-replaceable components.
The Storage Enclosure Processor (SEP) and RAID Controller are field-
replaceable but they require you to power down the VTrak.
Figure 1. Field Replaceable Units (FRUs) on VTrak
The primary means to identify and diagnose problems on VTrak is to observe and
interpret LED colors. A discussion of this process is found on the next two pages.
All hot-swappable components can be fully diagnosed with LEDs, although the
Command Line Utility (CLU) and WebPAM each offer you additional help to make
and confirm your diagnosis. See page 205 additional information.
