Component Minimum (inches) Maximum (inches) Notes
82562EH L=4.5 L=10 Signal Lines LAN_RXD[2:1] and
LAN_TXD[2:1] not connected
82562ET L=3.5 L=10
CNR L=3 L=9
NOTE: Length of trace from connector to LOM should be 0.5 to 3 inches.
9.9.1.3 LOM/CNR Interconnect
The following guidelines allow for an all inclusive motherboard solution. This layout combines
LOM, dual footprint, and the CNR solutions. The resistor pack ensures that either a CNR option or
a LAN on motherboard option can be implemented at one time. The recommended trace routing
lengths are shown in Figure 119. LOM/CNR Interconnect.
