4.2 BB-1072 Expansion Chassis Mounting Locations
The BB-1072 enclosure with an ECH-1048 expander chassis is equipped with two long
extension cables: one for the 26-pin ribbon cable (MD-575) and one for the four-wire power
cable (MD-580). Circuit adder modules are installed from right to left in two tiers (back then
front). These circuit adder modules are cabled in the same way as the main chassis, except
that the first module on the back tier to the right connects (via the MD-575 and MD-580
extension cables) to the second module in the main chassis. The fourth module on the front
tier to the right connects (via MD-575 and MD-580 extension cables) to the third module on the
first tier to the left. In other words, follow a continuous right to left, bottom to top, and back to
front installation order (see Figure 7).
