Adding Netfinity FAStT EXP500 expansion units
to a loop:
If you want to add an additional Netfinity
FAStT EXP500 expansion unit to a loop, cable the GBIC
input port on the existing ESM board (shown as First
EXP500 in the figure below) to a GBIC output port on the
new Netfinity FAStT EXP500 expansion unit. You can
daisy-chain additional Netfinity FAStT EXP500 expansion
units until the loop reaches the maximum defined by the
controller. The controller might also have cabling
configuration information or restrictions that you must
follow.
