The mounting bracket for both the ISIHI-2/S and the ISIHI-2U is similar,
except the LEDs are labeled differently. Each mounting bracket has two sets
of LED indicators that indicate status and line activity. Below, and on the
next page, are graphics for each bracket along with descriptions of the LED
indicators.
