FID Entry Point
Figure 8 lists each FRU identifier (Reported FID) and the field replaceable units (FRUs) to change, or
problem areas to investigate under FRU Name. The figure (beginning with the Third Release) also
contains the Repair Sequence you should follow in performing procedures or FRU replacements. Also
included are page Reference or Instruction to the removal and replacement procedure for the FRU.
Each FRU or problem is identified by name. The technical area code (TAC), provided here and in the
CARR section, is to assist you with call reporting. The Duration in hours is intended to give you some
idea of how long each FRU removal and replacement procedure will take. These numbers, along with the
time it takes to remove and replace decorative covers (see times given for covers in the CARR section)
should give you a ball park estimate of what time you can expect to spend replacing the parts. These
times do not include diagnose and checkout time.
FIDs are displayed on the operator/CE panel in a FID message and in the error log. For example, if the
message is FID1 90, 1 is the severity and 90 is the FID. “Intervention Screens” on page PANEL-9
describes the different types of messages and their impact on 3570 availability. The FID relates to the
FRUs that have the highest probability of causing the problem. Only the reported FID is displayed on the
panel and in the FID log. See Figure 8 for the complete list of FIDs and associated FRUs. Always replace
the FRU or perform the recommended procedure in the order of Repair Sequence which takes into
consideration failure probability.
If the FID has cable FRUs in the FRU list, reseat the cable FRUs before replacing any FRU in the list.
If you are servicing a 3570 model that is Rack installed, two people are required to lift the device from the
rack. Refer to “Installing the 3570 in a Rack” on page INST-20 for the procedure to use the hoist in cases
where you are alone.
The service information message (SIM) record, which the 3570 sends to the host, also has the reported
FID information. See “Service Information Messages (SIMs)” on page MSG-2.

00 The drive serial number is the default value
1 Invalid drive serial number — — Enter valid drive serial number.
Go to “Drive Serial
Number—Library Models Only” on
page PROC-36.
01 The drive logic card serial number is the default value
1 Invalid drive logic card serial
number. This number is set
when the card is built and
cannot be changed in the field. — — Replace the drive logic card. The
procedure is at “FID EA: Drive
Logic Card” on page CARR-16. If
this does not resolve the problem,
call for support.
03 Invalid setup detected
1 Configuration problem — — Ensure the config/install options
are correct (library models only).
