SCSI Bus Termination

The Model 140 and Model 240 have a fast/wide SCSI-2 bus which can support internal and external SCSI devices. However, each controller on these SCSI busses must have a unique SCSI id, and the SCSI busses must be properly terminated both internally and externally (if external devices are used) to ensure SCSI signal integrity.

For directions on setting the SCSI id on each device, consult the documentation for that device, as well as the

Systems

Adapters, Devices, and Cable Information for Multiple Bus

Model 140 Internal SCSI Bus Termination

The Model 140 internal SCSI chain must be terminated by the last drive in the chain, which must be configured as a self-terminating drive by setting jumpers on the drive. Please consult the documentation that came with your SCSI device.

Note: Only the last drive in each SCSI chain should be configured as

self-terminating.

External SCSI chains must be terminated by a separate SCSI terminator.

Power Cables

To avoid electrical shock, a power cable with a grounded attachment plug is provided. Use only properly grounded outlets.

Power cables used in the United States and Canada are listed by Underwriter's Laboratories (UL) and certified by the Canadian Standards Association (CSA). These power cords consist of:

 Electrical cables, Type SVT or SJT.  Attachment plugs complying with National Electrical Manufacturers Association

(NEMA) 5-15P. That is:

"For 115 V operation, use a UL listed cable set consisting of a minimum 18 AWG, Type SVT or SJT three-conductor cord a maximum of 15 feet in length and a parallel blade, grounding type attachment plug rated at 15 A, 125 V."

"For 230 V operation in the United States use a UL listed cable set consisting of a minimum 18 AWG, Type SVT or SJT three-conductor cable a maximum of 15 feet in length, and a tandem blade, grounding type attachment plug rated at 15 A, 250 V."

 Appliance couplers complying with International Electrotechnical Commission

(IEC) Standard 320, Sheet C13.

1-18 7043 43P Series Service Guide

Power cables used in other countries consist of the following:

 Electrical cables, Type HD21.  Attachment plugs approved by the appropriate testing organization for the

specific countries where they are used.

"For units set at 230 V (outside of U.S.): use a cable set consisting of a minimum 18 AWG cable and grounding type attachment plug rated 15 A, 250 V. The cable set should have the appropriate safety approvals for the country in which the equipment will be installed and should be marked HAR."

Refer to Chapter 9, “Parts Information” on page 9-1 to find the power cables that are available.

Service Inspection Guide

Perform a service inspection on the system when:

 The system is inspected for a maintenance agreement.  Service is requested and service has not recently been performed.  An alterations and attachments review is performed.  Changes have been made to the equipment that may affect the safe operation of

the equipment.

 External devices with separate power supplies have been attached.

If the inspection indicates an unacceptable safety condition, the condition must be corrected before anyone can service the machine.

Note: The correction of any unsafe condition is the responsibility of the owner of the system.

Perform the following checks:

1. Check the covers for sharp edges and for damage or alterations that expose the internal parts of the system unit.

2. Check the covers for proper fit to the system unit. They should be in place and secure.

3. Gently rock the system unit from side to side to determine if it is steady.

4. Set the power switch of the system unit to Off.

5. Disconnect the power cable.

6. Remove the covers.

Chapter 1. Reference Information 1-19

7. Check for alterations or attachments. If there are any, check for obvious safety hazards such as broken wires, sharp edges, or broken insulation.

8. Check the internal cables for damage.

9. Check for dirt, water, and any other contamination within the system unit.

10. Check the voltage switch on the back of the system unit to ensure that it matches the voltage at the outlet (Model 140 and M240. only.)

11. Check the external power cable for damage.

12. With the external power cable connected to the system unit, check for 0.1 ohm or less resistance between the ground lug on the external power cable plug and the metal frame.

13. Perform the following checks on each device that has its own power cables:

a. Check for damage to the power cord. b. Check for the correct grounded power cable. c. With the external power cable connected to the device, check for 0.1 ohm or

less resistance between the ground lug on the external power cable the metal frame of the device.

Chapter 2. Maintenance Analysis Procedures (MAPs)

This chapter contains Maintenance Analysis Procedures (MAPs) for the Model 140, Model 150, and Model 240.

Entry MAP

Notes:

1. When possible, run Online Diagnostics in Service Mode. Online Diagnostics perform additional functions, compared to Standalone Diagnostics. This ensures that the error state of the system is captured in NVRAM for your use in fixing the problem. The AIX error log and SMIT are only available when diagnostics are run from the hard drive.

2. Licensed programs frequently rely on either network configuration, vital product data (VPD) stored on the operator panel control assembly, or system board information to authorize program use. If the MAPs indicate that the network adapter, operator panel, or system board should be replaced, notify the system owner that new keys for licensed programs may be required.

3. If a network adapter or the system board is replaced, the network administrator must be notified so that the client IP addresses used by the server can be changed. In addition, the operating system configuration of the network controller may need to be changed in order to enable system startup, and any client or server that addresses this system should be updated. After completing the recommended actions in this chapter, go to "MAP 0410: Repair Checkout" in the

This procedure is used to locate power problems in system units. If a problem is detected, this procedure helps you isolate the problem to a failing unit.

Observe the following safety notice during service procedures.

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent and electrical shock.

Before installing or removing signal cables, ensure that the power cables for the system unit and all attached devices are unplugged.

Diagnostics Information for Multiple Bus

When adding or removing any additional devices to or from the system, ensure that the power cables for those devices are unplugged before the signal cables are connected. You must disconnect all power cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to prevent a possible shock from touching two surfaces with different electrical potentials.

During an electrical storm, do not connect cables for display stations, printers, telephones, or station protectors for communication lines.

CAUTION: This product is equipped with a three–wire power cable and plug for the user's safety. Use this power cable with a properly grounded electrical outlet to avoid electrical shock.

Diagnostics Information for Multiple Bus

Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For this procedure, diagnostics are run on a minimally-configured system. If a failure is detected on the minimally-configured system, the remaining FRUs are exchanged one at a time until the failing FRU is identified. If a failure is not detected, FRUs are added back until the failure occurs. The failure is then isolated to the failing FRU.

Notes:

1. This MAP assumes that a CD-ROM drive is installed and connected to the integrated SCSI adapter, and a Diagnostics CD-ROM disc is available.

2. If a power-on password or privileged-access password is installed, you are prompted to enter the password before the diagnostic CD-ROM loads.

3. The term "POST indicators" refer to the icons (graphic display) or device mnemonics (ASCII terminal) that appear during the power-on self-test (POST).

Because the minimum configurations for the Model 140 and Model 240 differ, this MAP is divided into 1540A for the Model 140 and 1540B for the Model 240.

 MAP 1540A: Minimum Configuration (for the Model 140 and Model 150) begins

on 2-22.

Error Code Description Action/

Possible Failing FRU

xxx=001 DIMM fails memory test. For more information:

1. Use the location code obtained from the SMS Error Log utility (described in “Step 1020-4” on page 2-11) to identify which DIMM is defective.

2. The "yy" values specify type of memory causing error. See “Memory PD Bits” on page 3-13 for definition of "yy."

Note: On the Model 240, there may be 2 DIMM related memory errors reported to indicate a DIMM pair. One of the 2 indicated DIMMs may be good, when replacing memory on this system replace 1 DIMM at a time, not both.

xxx=002 DIMM is not supported. Remove unsupported DIMM.

The "yy" values specify type of memory causing error. See “Memory PD Bits” on page 3-13 for definition of "yy."

Note: Memory DIMMs must be installed/removed in pairs on the Model

240.

28030xxx Real-time clock (RTC) error. Note: Errors reported against the Real

Time Clock can be caused by low battery voltage and (more rarely) power outages that occur during normal system usage. These errors are warnings that the Real Time Clock data content needs to be re-established and do not require any FRU replacement unless the error is persistent. When one of these errors occurs, the power-on password and time and date information have been lost.

 To set/restore a power-on

password, use the SMS utility.

 To set/restore the time and date,

use the operating system facility.

If the error is persistent, replace the battery.

If the error is persistent after battery replacement, replace the system board. (See notes on page 3-1.)
