FRU Removal and Replacement
This chapter provides information about removing and replacing a Field Replaceable
Unit (FRU). Part 1 describes FRU removal and replacement for Model 400t and 400dl
systems. Part 2 describes FRU removal and replacement for the Model 400s system.
5.1 Introduction
The FRU is the actual hardware that the CE replaces at the customer site. The CE im-
plements the actual replacement strategy based on the factors at each customer site.
HP Apollo systems have the following maintenance strategy where the FRUs are dif
-
ferent at each level.
• Level 1 is the Subassembly level. At this level, the CE performs system repairs
at the customer site with a replaceable part. These parts include PCBs, power
supplies, monitors, keyboards, fans, cables, and complete Winchester disk
drives. These replacement parts are stocked at each branch office.
• Level 2 is the Major Unit level. At this level, the CE replaces entire systems in
accordance with the option swap policy.
5.2 Recommended Equipment
You need the following tools and equipment to properly repair the system:
• Standard CE tool kit
• Antistatic kit, including antistatic mat, static straps, and antistatic bags for PC
