!WARNING: POSSIBLE EQUIPMENT DAMAGE! Reversed polarities on the DC power feed can irreparably damage the BitStorm 1900 shelf components. Be certain power feeds are connected properly to the power source, with the red leads connected to the DC supply as shown in the table above. Note that this is the opposite of other (non-telecommunications) applications, in which red leads are usually connected to the "+" terminal.
