Configuration

For NX5820 systems, if the channel racks are daisy chained to one another and the CEC

 

section, use 9 Pin D to 9 Pin D Power Net cables (Style CBL8820-xxx, cable assembly 3446

 

6110-xxx).

 

The 9 Pin “Power Net In” connector (J5) is located on the left side in the rear of the channel

 

rack. The 9 Pin “Power Net Out” connector (J4) is next to it.

 

 

Power Net

Switches 3 (MSB) through 8 (LSB) are used for the Power Net address assigned to the

Address

channel rack. Switch 1 and 2 are not applicable.

 

 

Termination

Channel racks have internal termination. Only install Power Net terminator activation

 

jumpers at JP2 and JP4 if this channel rack is the last on the Power Net chain.
