With the power supply turned OFF, connect the -48 V DC (260W) or 110 V AC (260W) power source according to the following table and Figure 2-8, "Typical DC Power Harness Connection to -48 V DC (260W) Power Source," on page 51.

WARNING: POSSIBLE EQUIPMENT DAMAGE! With the -48 V DC power supply, reversed polarities on the power feed can irreparably damage the BitStorm 1900 shelf components. Be certain that power feeds are connected properly to the power source, with the red lead connected to the -48 V DC supply (negative terminal) as shown in the table below. Note that this is the opposite of other (non-telecommunications) applications, in which the red lead is usually connected to the positive (+) terminal.

Lead
Red	-48	V DC supply	Negative (-)	10 AMP, 260W
