Liquid Bearing Tube IB Two-Step Upgrade

Prerequisites

Overview

This document explains the procedure of Liquid Bearing Tube IB upgrade for Optima CT660. This manual refers some procedures that already released (i.e. LFC procedure, Tube replacement procedure, etc.). Refer to Optima CT660 Service Method (Gen.) CD-ROM (5366080-2EN rev.24 or later) in that cases.

There are two procedures. Two-Step upgrade procedure is used when LB Tube installation is done separately from Software upgrade and other hardware modification. One-Time upgrade procedure is used when both of Software upgrade, hardware modification and LB Tube installation are done at the same time.

System Requirement

Optima CT660 with following System software

10HW33.8 with any Service Pack (a.k.a. Cj Phase1.5) → Requires Phase2.5 Upgrade kit.
12HW28.8 with any Service Pack (a.k.a. Cj Phase2.5)
14HW30.3 (a.k.a. Cj Phase2.5 SP4)

note:

This manual is for FMI26844 and the sites that are implemented FMI26844.

The following shows the flowchart used in this document.

Flowchart of Proactive Upgrade (Two-Step Upgrade)

1 First Step of Proactive Upgrade

Procedure

notice

If the system software version is 10HW33.8 (with any Service Pack), need to upgrade using Cj Phase2.5 upgrade kit. The first step of Liquid Bearing Tube upgrade is LFC, and the software 15HW25.x should be used on Cj Phase2.5 upgrade procedure instead of provided software package.

Check the HEMIT Tank part number. If it’s 2237336, 2237336-2 or 2237336-3, Attach the “HEMIT Notice Label - Replace before LB installation” on HEMIT Tank (5445414). 2237336-4 or 2237336-5 are Optima CT660 HEMIT.

Order HEMIT FRU 2246223-4 and replace HEMIT Tank before LB Tube replacement at next step.
