The Thinkpad console uses PC Card (once known as PCMCIA) adapters. Theadapters are either 16-Bit (PCMCIA) or 32-Bit (CardBus). Only the 2647 (T2x)Thinkpad uses CardBus and Mini-PCI network adapters. Adapter configuration isdone via software during initialization and does not have to be checked. Startingwith zSeries 900, the parallel port connection between Thinkpad and CEC hasbeen replaced by the MiniPCI Ethernet adapter. The adapter is accessed behind aremoveable plate located on the bottom of the Thinkpad, directly above the

| Model/Type/S-N sticker. For T20 and T22, MiniPCI Ethernet may be combined with| modem adapter. For T23, the MiniPCI is a daughter card secured with two screws| and located next to the modem adapter. The cable socket is at the rear of the

Thinkpad, between the modem and DC barrel input connectors.

System Unit maintenance tests are performed from:

| � 2647 (T20, T22) PC Doctor Diagnostic Diskettes (2 diskettes). 2647 (T23) PC| Doctor Diagnostic Diskettes (3 diskettes). CardBus (32-Bit) maintenance

procedures are performed using a diagnostic diskette (T2xLAN). MiniPCIEthernet maintenance procedures are performed using the PC Doctordiagnostic diskettes.

� 26xx (all other TPs) are performed from the "Test" option under the "EasySetup" utility program. The Easy Setup utility is stored in the Thinkpad'spermanent memory. PC Card (16-Bit) maintenance procedures are performedusing a diagnostic diskette (Token-Ring) or a DOS boot diskette to rundiagnostic tests from the DASD.

Thinkpads receive power from the CEC frame and do not have a battery packinstalled. If you are directed to power off the Thinkpad, use the following procedure:

� If a SEPC is mounted behind the Thinkpad, unplug its power cable to theThinkpad. The Thinkpad may have to be removed from the tray.

� If no SEPC is mounted behind the Thinkpad, do one of the following:

– Remove the Thinkpad from the tray and unplug the DC power cableconnecting the Thinkpad.

– Unplug the Thinkpad power cable from the Bulk Power Interface (BPI).Verify BPI connector location by following the Thinkpad power cable.

Modifications have been made to ThinkPads used as Support Elements to keep theThinkPad powered up with the S/390 hardware. These modifications must be in


place to ensure the availability of the S/390. Use the table below to verify thesemodifications are present on the ThinkPad you are working on:

2620 (360)

� External clip installed forcing the on/off switch to the 'on' position

2625 (365)

� Internal stick installed forcing the on/off switch to the 'on' position

2635 (380)

� External clip installed forcing the on/off switch to the 'on' position

2645 (600)

� Circuitry module attached to the system expansion connector (240 pin mini Dshell connector next to the __/_ symbol). The module is located at the back ofthe ThinkPad towards the middle and provides a power on when SEPC barrelconnector voltage is sensed through the ThinkPad.

� Using the Easy Setup utility, configure the ThinkPad to support the "Wake onLAN" function. See “2645 (600) ThinkPad Configuration” on page 2-51.

2647 (T2x)

� Circuitry module attached to the docking station socket underneath theThinkpad providing all power. The power-on push button is covered with a cap.

For support elements, 16Mbps Token Ring speed is the only value supported.

If you have an R1, R2, or R3 based system using a 2625 or 2635 ThinkPad as asupport element, you may have a black border of approximately 2.5 cm (1 inch)around the display. This is normal operation.

For a 2620 or 2625 ThinkPad, the following frus may be replaced with the systemunit in the tray.

� Hard Disk Drive� Floppy Disk Drive

� Memory Card� Standby or Backup Battery� PC Card Network Adapter (Token-Ring/Ethernet)� Network Cable (Token-Ring/Ethernet)

For other 2620 or 2625 ThinkPad frus, it is recommended that you remove thesupport element because of the many small parts.

For other ThinkPads, the following frus may be replaced:

� Memory DIMM � Backup Battery� PC Card Network Adapter (Token-Ring/Ethernet)� MiniPCI Ethernet Adapter� Network Cable (Token-Ring/Ethernet)

Note: For any frus not listed, the ThinkPad is to be replaced.
