Problem affecting an individual thin processor node’s integrated Ethernet connection.
– Open the rear cover of the RS/6000 SP frame, and locate the proper processor node.
– Use the following table to reseat or replace components.
Priority Component Action
1 T-adaptor (coax) or TTP transceiver
(N00-BH-J5) 1. Check the connection at the T-adaptor (coax) or
TTP transceiver on the integrated Ethernet card
(N00-BH-J5), and tighten as necessary. For TTP,
also check cable and connection at the TTP HUB,
and verify correct plug position.
2. Verify that internal and external cables are con-
nected to the correct integrated or Micro Channel
Ethernet card, respectively.
3. If no problem was found continue at Priority 2; oth-
erwise, verify fix at Step 016 on page 1-292.
2 T-adaptor (coax) or TTP transceiver
(N00-BH-J5) Replace component. If no problem is found, go to Pri-
ority 3.
3 (Planar power problem) 1. From the control workstation, reset this processor
node.
2. Check 3-digit LEDs for any non-blank condition
during IPL.
3. If the 3-digit LEDs are always blank, go to Step 006
on page 1-51 to fix the planar power problem. Oth-
erwise, continue at Priority 4.
4 Ethernet riser card 1. Put circuit breaker(s) at front of processor node in
the Off (‘0’) position, then remove processor node
from frame.
2. Remove processor node cover.
3. If a 332 MHz SMP or POWER3 SMP node, go to
Priority 5. If other node, continue with next step.
4. Replace the integrated Ethernet riser card.
5. Continue at Step 013.
5 I/O planar card 1. Replace the I/O planar card. Make sure that all
cards and cables are reinstalled properly following
replacement.
2. Continue at Step 013.
6 All replaced Call next level of support.
013
Component reseated or replaced.
– Reinstall processor node top cover.
– Reinstall processor node in frame. Make sure to reconnect cables at back of processor node.
– Put circuit breaker(s) at the front of processor node in the On (‘1’) position.
– Go to Step 016 on page 1-292 to verify fix.
