2.) Connect power for -48 V DC. (If you are installing an AC fan tray, proceed to step 3 to connect power for the 110 V AC fan tray.)

a.) The -48 V DC connection requires a 14-gauge stranded cable (not included).

b.) Connect the black power feed to the positive terminal and the red power feed to the negative terminal.

NOTE: This is the opposite of how non-telecommunications electronics are connected.

c.) Route the other end to the matching connector on the BitStorm 1900 backplane.

d.) LEDs indicate fan failure.

NOTE: The power supply for the multiplexer must also be -48 V DC.
