Connecting a 10BASE-T Segment to an EPIM-T

For proper operation, the EPIM-T module to be configured for
NOTE
use in the ESXMIM module must be of EPIM board revision 04
or greater. Board revision numbers are found following the part
number printed on the Printed Circuit Board of the EPIM.
Before connecting a segment to the EPIM-T, check each end of the
segment to determine wire crossover. If the wires do not cross over, use
the switch on the EPIM-T to internally cross over the RJ45 port. Refer to
Figure 3-7 to properly set the EPIM-T crossover switch.
To establish a link, you must have an odd number of
NOTE
crossovers (preferably one) between 10BASE-T devices of the
same type (i.e., from repeater to repeater or transceiver to
transceiver).
