MAP 0190: Processor Node Function
Condition of LEDs
Action
LEDs stop at 214/215 during IPL,
Obtained of the following RS/6000 SRNs:
– 128- 100 through 195
– 143- 714/715/814/815
– 144- 514/515
– 146- 014/015/314/315
– 148- 111/112/114/115/190/197
1. Use power MAPs in RS/6000 Installation and
Service Guide referencing “MAP 0140: Thin
Node/Thin Node 2 Environment” on page 1-50,
“MAP 0150: 120/160 MHz Thin Node
Environment” on page 1-60, “MAP 0210: Wide
Processor Node Environment” on page 1-98, or
“MAP 0250: 604 or 604e High Node Environment”
on page 1-124, as required.
2. Go to Step 009 on page 1-93 to check for any
additional actions required to complete a FRU
replacement.
LEDs cycling through values in the range 222 -
260 or a constant 269 during IPL.
– Processor node is unable to boot.
Go to “MAP 0200: Processor IPL Problem” on
page 1-94.
LEDs stop at 262 during IPL
1. If processor node mode switch is not set for
SERVICE mode, go to “MAP 0170: Thin
Processor Node Control” on page 1-74, “MAP
0230: Wide Processor Node Control” on
page 1-110, or “MAP 0270: 604 or 604e High
Node Control” on page 1-135 to fix mode switch
problems.
2. From the node front panel, click on “OPEN TTY”
to open the TTY console on this processor node.
3. Press ‘1’ then ENTER in the TTY console window.
4. SERVICE IPL should continue.
LEDs stop at 292 during IPL
Problem configuring SCSI/SSA/serial device.
If the failing device is the device you want to boot
from, or is another device in the boot chain (before
your device), the system will not boot. To isolate the
problem, minimum configuration of DASD bootable
adapters may be required. See "Diagnosing an LED
292 Hang Condition" in
IBM RS/6000 SP: Mainte-
nance Information, Volume 3, Locations and Service
Procedures.
LEDs stop at 553 or 570 during IPL
Problem configuring SCSI device.
1. If processor is currently booting from disk, go to
“MAP 0200: Processor IPL Problem” on
page 1-94.
2. If processor is booting over network and other
devices are still attached, disconnect SCSI
cable(s) from SCSI MCA or I/O planar, then go to
Step 003 on page 1-95.
3. If processor is booting over network and no
devices are attached, at SCSI MCA or I/O planar,
then replace SCSI MCA or I/O planar.
LEDs stop at constant 83u OR 888-103-762-xxx
– Problem with HiPS Adapter-2 or SP Adapter.
Go to “MAP 0540: Switch Function” on page 1-322
Note: LED 83u corresponds to SRN of type 83C-
xxx.
LEDs stop at 862 during IPL
– Problem with BMCA feature.
Go to “MAP 0560: Block Multiplexer Channel Adapter
(BMCA)” on page 1-353.
