J15, +/-12 V Present Header

A 2-pin header on the board is used to allow operation with or without +12 V or -12 V supplies.
A jumper placed between pins 1 and 2 allows board operation without +/-12 V supplies. No
jumper implies that +12 V and -12 V are present at the backplane.

J20, Safe Start Header

A 3-pin header is used to select programmed or safe start settings. No jumper or a jumper
placed between pins 1 and 2 allows programmed settings (e.g., VPD, SPD) to be used during
boot. A jumper placed between pins 2 and 3 allows the safe start settings (Safe VPD, SPD
parameters, GEVs ignored) to be used.
