drawer with either a screwdriver or a 5/16-inch wrench (see Figure 2–3).
To pull out the CPU drawer, grasp both sides of the drawer’s front edge and
slide the entire drawer forward from the enclosure until you hear a click. This
means that the latches on either of the drawer’s slides have sprung out slightly
to engage (see Figure 2–6).
Check to see that both latches are engaged; if not, pull the drawer out carefully
until the remaining one engages, and the middle cover on the top of the drawer
(air plenum compartment, Section 2.5) can be raised and latched in a vertical
position.

2–6 Removing and Replacing the CPU/Daughter Card

To push in the CPU drawer after installation, hold the spring tabs in (they should
be protruding through the holes) while gently sliding the drawer as depicted in
Figure 2–7.
As the CPU drawer is pushed or pulled, the cable arm extends or retracts,
keeping the cables organized and out of the way.

Diagnostics and Testing
3.1 Acceptance Testing
The following tests ensure that the CPU/daughter card you just installed is in
proper operating condition. In addition, problems such as cabling or configuration
will be found before the operating system is loaded/booted.
Note
These procedures are an overview of the acceptance testing steps.
Detailed information can be found in the DECsystem 5900 Service Guide,
EK–D590A–PS.

3.1.1 Power-Up Self-Test (POST)
1. Turn on the upgraded CPU drawer.
2. Watch the console terminal for a running display of the POST tests. Most will
overwrite the display from previous tests as they are run.
There should be no errors in this 2-minute (approx.) test.
3. If there is no display, look for a green power LED on the front of the drawer,
and see if the red LEDs on the rear of the CPU drawer are changing state as
the tests run. If the LEDSs are not on, check for a power or cabling problem.

3.1.2 System Configuration Check
Use the cnfg utility to assure that the system can "see" all the memory modules,
NVRAM, TURBOchannel options and SCSI devices. There can only be one SCSI
device 0, 1, 2, 3, 4, 5, or 6 on each SCSI bus.
Pay particular attention to SCSI IDs on configurations that use split SCSI format
or have two CPUs sharing a single mass storage drawer. If the system cannot see
all the devices on each SCSI bus or on the system module, check the cable/module
connections or the SCSI IDs.

Diagnostics and Testing 3–1

Run config by entering cnfg x where x = the TURBOchannel bus ID: 0, 1, 2, or 3;
3 is also used for the system module.

3.1.3 Extended ROM Tests
Run the extended tests on memory, cache, floating point, Ethernet, prcache and
TLB. Use of the -l command option in the command string (t -l 3/misc/halt) will
cause the tests to loop until a ^c is typed. Table 3–1 is provided as a guideline.

3.1.4 SCSI Test Commands
Note
For more detailed information consult the DECsystem 5900 Service Guide,
EK–D590A–PS.

To test SCSI controllers, configurations, and new devices that were added, run
the scsi/cntl (SCSI controller), scsi/sdiag (send diagnostic), and the scsi/target
tests (test SCSI devices) on the SCSI controller(s) and newly added SCSI devices.

3–4 Diagnostics and Testing

Caution
The [w] parameter on the scsi/target test may cause data loss; use it only
on newly installed disk devices which have no data on them, or use a
scratch tape in tape devices.

3.2 Modifying ULTRIX
These steps will vary with the scope of the changes to the system configuration
that have been made during the CPU/daughter card upgrade. Depending on
the site, you and/or the customer/system manager should consult the Guide to
Installing ULTRIX, AA–PBL0D–TE, and other ULTRIX documentation for more
details on adding devices.

A
Mandatory Card Return Procedure and
Forms
The used R3000A CPU/daughter card must be returned to Digital Equipment
Corporation. Digital Services personnel must ensure that the instructions to
repackage and return used CPU/daughter cards are followed. The instructions
apply only to United States area installations.
For installations outside the United States area, contact the local Digital
Equipment Corporation office for return destination instructions.

A.1 Return Procedure
Return the CPU/daghter card as follows:
1. Obtain the serial number of the system being converted. Customer
Administrative Services (CAS), cannot process the order without this
serial number.
2. Ensure that the serial number is on the purchase order.
3. Issue a hardcopy quotation to the customer, referencing the serial number,
and state the following:
"Return of the replaced card to Digital is a condition of sale for this
conversion. Failure to return the card will result in a penalty charge.
Installation of hardware by Digital Services personnel is required."
4. Pack the used card with the packaging material set aside from the carton
of the conversion kit, first in the nickel-plated bag, then in the pink plastic
wrapping, and finally in the box.
5. Complete the Digital Services Worksheet in Section A.2. It documents the
work you performed.
Return the worksheet to your contract administrator at the branch office.

Mandatory Card Return Procedure and Forms A–1

6. Contact your local Digital CAS office to obtain information for the Installation
Receipt and the Return Material Checklist in Section A.2. Section A.3 lists
the CAS district offices and their phone numbers.
Ask the CAS representative for a return authorization (RA) number. CAS
will contact the customer to arrange for carrier pickup and return of the card
to Digital Equipment Corporation.
7. Complete both copies of the Installation Receipt.
The first copy is the customer’s receipt. It shows that the installation was
completed and that Digital Services contacted CAS.
Return the second copy to Digital Services along with the used card to ensure
that the customer does not incur a penalty charge.
8. Complete the Returned Material Checklist.
Return the checklist with the used card.
9. Place the self-adhesive mailing label on the box to be returned.
Write the return authorization (RA) number in the space provided on the
label.
10. Seal the box for shipment.
Refer questions regarding the return procedure to the local account
representative.
Note
Customers who do not return their used CPU cards will be charged a fee.
