Figure 1-31 is an illustration of the MGX 8830 switch with its door attached. Light pipes in the door
display the status of the PXM1E cards. The MGX 8830/B has a redesigned door with a slightly different
appearance than the MGX 8830 door, but they are functionally equivalent.
For the MGX 8830 switch, the door is not required to meet electromagnetic interference (EMI)
requirements. Either installed blank faceplates or installed cards help meet that requirement.
