To facilitate on-line replacement on SG2440s equipped with redundant power supplies, you can

The following subsections present information to help you configure the forward path of the
SG2440-XXX-XXX-*. Figure 3-2 illustrates the upper-half housing or lid of the SG2440 and

You can configure the SG2440 forward path by using the SG2-R/* receiver and one of four
configuration plug-in boards in the lid motherboard. Each board has a specific function and
receiver combination associated with it. Each board is clearly labeled and can be distinguished
from a return-path plug-in board by the row of pins at the bottom of each board. For detailed
information on the SG2-R/* receiver, see Section 4, “Optical Modules.”
