3.5 CONNECTING TO THE NETWORK
This section gives procedures for connecting the EMM-E6 and various
EPIMs to the network. Refer to the list below and follow the procedures
in the subsection for appropriate module type:
• Connecting a 10BASE-T Segment to an EPIM-T: Section 3.5.1
• Connecting a 10BASE-F Segment to an EPIM-F2 or EPIM-F3:
Section 3.5.2
• Connecting a 10BASE-F Segment to an EPIM-F1: Section 3.5.3
• Connecting an AUI Segment to an EPIM-X or EPIM-A:
Section 3.5.4
• Connecting a 10BASE2 Segment to an EPIM-C: Section 3.5.5
3.5.1 Connecting a 10BASE-T Segment to an EPIM-T
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 3-5 to properly set the EPIM-T crossover switch.
NOTE
For proper operation, the EPIM-T module to be configured for
use in the EMM-E6 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.
NOTE
To establish a link, you must have an odd number of
crossovers (preferably one) between 10BASE-T devices of the
same type (i.e., from repeater to repeater or transceiver to
transceiver).
