Safety and environmental notices Safety notices (in English) For general information concerning safety , refer to Electrical Safety for IBM Customer Engineers (S229-8124). For a copy of this publication, contact your IBM marketing representative or the IBM branch office serving your locality .
Before you connect the power cable of this product to ac power , verify that the power receptacle is correctly grounded and has the correct voltage. ( SPSFD004 ) DANGER During an electrical storm, do not connect or disconnect any cable that has a conductive outer surface or a conductive connector .
DANGER The frame main circuit breaker and the controller must not be switched on again now . Before disconnecting the power cables from the power receptacles, ensure that the customer’s branch distribution circuit breakers (customer power source circuit breakers) are Off and tagged with DO NOT OPERA TE tags, S229-0237.
CAUTION: Due to weight of each thin node (under 18 Kg [40 lbs]), use care when removing and replacing thin nodes above shoulder height. ( SPSFC005 ) CAUTION: The wide node weight may exceed 32 Kg (70.5 lbs). ( SPSFC006 ) CAUTION: Do not open more than one wide node or switch assembly drawer at a time.
CAUTION: When using step ladder or step stool, be sure that the work surface is level and the step ladder or step stool is in good working order . ( SPSFC016 ) CAUTION: Portable ladders present a serious safety hazard if not used properly .

About this book This book covers the SP Switch2 only . Refer to RS/6000 SP: SP Switch Service Guide , GA22-7443 for information related to the SP Switch.
User’s responsibilities Before calling IBM ® for service, the system administrator should use the problem determination section of the Parallel System Support Programs for AIX ® : Diagnosis Guide (GA22-7350), for initial problem determination.
Chapter 1. Maintenance Analysis Procedures (MAPs) This chapter provides information for identifying problems and guides you to the most likely failed Field Replaceable Unit (FRU). The MAPs then refer you to the FRU Removal/Replacement procedures for the corrective action.
Switch Connection T ypes Standard Node Processor nodes in 9076 SP frames are attached to the switches with switch cables. Switch-to-Switch Connections between switches. Switch Assembly Description SP Switch2 Each switch chip has its own clock and all clocks communicate through the switch data cables.
There are two LEDs on the front of each switch assembly . For quick reference, their definitions are as follows: Figure 1-1. SP Switch2 Assembly High-Level Diagram Switch Description and Problem Determination (MAP 0590) Chapter 1.
Y ellow (Environment) LED Off No environmental problems detected by switch supervisor card. On W arning of environmental condition out of nominal range. Preventative Maintenance should be scheduled for this switch. Flashing Serious environmental condition detected; power shut off.
Note: In a frame with processor nodes, entries for the switch will refer to “node17” or “slot17”. In a multi-switch frame, switches will be listed as even slot addresses. Notes: 1. SP Switch2 advanced diagnostics use the 8.75 meter data cable provided by the SPS feature bill of material.

Switch power (MAP 0610) Purpose of this MAP This MAP provides diagnostic steps for resolving problems related to SP Switch2 power .
Step 0610-004 The green switch supervisor LED is Off . 1. Make certain that the switch power cable is properly connected to jack J1 on the switch and on the SEPBU. 2. Place the inline switch on the switch power cable into the On (‘1’) position if it is not already in that position.
Step 0610-009 The switch circuit breaker no longer trips to the Off (‘0’) position when a fan/power supply pair is removed. 1. Reinstall the power supply into the switch. 2. Check circuit breaker . 3. Does the circuit breaker still trip? v If yes, go to “Step 0610-010”.
3. If all interposers have been tested, go to “Step 0610-004” on page 1-14. Step 0610-017 Y ou tested all interposers and the circuit breaker still trips. 1. Replace the circuit breaker assembly . 2. Check the circuit breaker . 3. Does the circuit breaker still trip? v If yes, go to “Step 0610-018”.
Step 0610-022 The switch’s front panel power LED remained Off after replacing the LED power extension cable. 1. Replace the switch planar . v Refer to “Removing the switch planar” on page 4-7 and “Replacing the switch planar” on page 4-8 2.
