3.8.5 Installing a Multi-layer Module into the Chassis
Follow the instructions illustrated in Figure 3.13 to install a pair of loop control/expander modules
into CHS-4N or CHS-M3. See Figure 3.14 to install loop control/expander modules in CHS-4L.
1.
Angle the module into the chassis so that the upper end of the rear board (or boards) fits into
the top slot.
2.
Bring the module back down so that the lower board edges slip into the bottom slots.
3.
Secure the module to the chassis with the two module screws. Tighten securely.
