System reference code list

In these tables, locate the system reference code (SRC) that you have displayed. In the table, xxxx can be any number 0 through 9 or letter A through F.

The SRCs are grouped in ranges, although the recovery for each range might not apply to every SRC within the range. If you cannot find your SRC range in this table, call your next level of support.

The codes in this list are organized by their first character, with numbers coming before letters. To navigate this listing, click or go to the following number or letter that matches the first character of your SRC. Then, select your SRC from the list provided.

For each SRC range, there is a brief description of what the SRC range indicates, and what you need to do. If the recommendation does not solve the problem, or if there is no recommended way to solve the problem, contact your hardware service provider.
