Modules must be installed in the correct position in the chassis. Left modules must be
installed in one of the two left slots and right modules must be installed in one of the two
right slots. All laser fiber pigtails point toward the center of the chassis. In addition,
channel numbers on the modules must be verified or changed in order to match the
electrical connections with the channel numbers on the back of the chassis. The left
most module has channels 1-4, the middle left module has channels 5-8, the middle right
module has channels 9-12, and the right most module has channels 13-16. Within each
module, the least significant number is at the back with increasing numbers moving
toward the front of the chassis. See Figure 4.1.
