IBM Power PS700 - Location Codes

Location codes
Location codes identify components of the blade server. Location codes are displayed with some error
codes to identify the blade server component that is causing the error.
See “System-board connectors” on page 8 for component locations.
Notes:
1. Location codes do not indicate the location of the blade server within the BladeCenter unit. The codes
identify components of the blade server only.
2. For checkpoints with no associated location code, see “Light path diagnostics” on page 214 to identify
the failing component when there is a hang condition.
3. For checkpoints with location codes, use the following table to identify the failing component when
there is a hang condition.
4. For 8-digit codes not listed in Table 4, see the “Checkout procedure” on page 184.
