B: Installing Silicon Graphics Prism Modules Into a Rack
Programming L1 Rack and Slot Numbers
Each module in a system contains a Level 1 controller (L1). This controller should be programmed
with the location of the brick in which it is installed. Programming the L1 with the correct rack
and slot numbers allows for easier system maintenance and diagnostics, and is necessary for
predictable operation of the system.
When a module is connected to AC power, the L1 display will indicate its position by displaying
a string of the form XXXyZZ (for example, “001c12”).
Decode this string as follows:
“XXX” is the rack number (in this example, rack 001)
“y” is the module type (in this case, c indicates a compute module)
“ZZ” is the “U” number within that rack, counting from the bottom (in this case, slot 12).
If the position indicated on an L1 display is not correct, you should correct it as follows:
1.
Connect a serial terminal to the console port on the brick in question.
2.
Display the current location setting in the L1:
001c12-L1>
brick
rack: 001 slot: 12 partition: 0 type: C source: EEPROM
Enter the new rack number:
001c12-L1>
brick rack 1
brick rack set to 001
3.
Enter the new slot number:
001c12-L1>
brick slot 7
brick slot set to 07
4.
Verify the newly entered information:
001c12-L1>
brick
rack: 001 slot: 07 partition: 0 type: C source: EEPROM
If other bricks need to be changed, repeat steps 1 through 4 for each additional brick.
