specifications in the
Appendix B,
for each GPIM carefully before connecting a GPIM to the
network.
3.7.1
GPIM-09 Connection Using Multimode Cable
To connect the GPIM-09 to the network using multimode fiber, perform the following steps:
1.
Connect Launch Mode Conditioning cable to the multimode fiber optic on both ends of the
multimode cable, before connecting the GPIM-09 to the multimode fiber optic cabling. See
Figure 3-8
.

GPIM-09 Launch Mode Conditioning Cable Connection
2.
Once the Launch Mode Conditioning cable is connected to the ends of the multimode fiber
optic cable, proceed to
Section 3.7.2
to complete the installation to the GPIM-09 device.
NOTES
An odd number of crossovers (preferably one) must be maintained between like devices
so that the transmit port of one device is connected to the receive port of the other
device and vice versa.
If the fiber optic cable being used has SC style connectors that do not resemble MIC
style connectors, or has SC connectors on one end and a different type on the other,
such as ST connectors, ensure that the proper cable cross-over occurs.
NOTE
When using multimode fiber optic cable for the GPIM-09 (long wave length transceiver),
connect Launch Mode Conditioning cable as detailed in the following procedure
(
Section 3.7.1
). The following procedure is not needed when connecting single mode
fiber optic cable to the GPIM-09. Launch Mode Conditioning cables are available from
Cabletron Systems.
