* See “11 P.C. board exchange procedures”.
Refer to (*).
(*) Concerning the “00” auxiliary code
1)
The wrong model setting for the interface P.C. board was
used when the board was replaced with the service P.C. board.
2)
The wrong model setting for the fan IPDU P.C. board was
used when the board was replaced with the service P.C. board.
In such a case, the sub-codes “08” to “0F” for L29, which are
not included in the table above, may be displayed.
