Figure 8–1. Element mounting locations
NOTE:
Model 2100 enclosures support only two I/O modules; whereas Model 2200 enclosures
support six I/O modules. For Model 2100 enclosures, a blank panel covers the four vacant I/O
module bays.
A label affixed to each element identifies its replacement part number (see Figure 8–2,
1).
Use this number to order a replacement element. Also, use this number to verify the proper
element was received, before beginning any replacement procedure.
