Cabletron Systems ESX-1320 User Manual

This section gives procedures for connecting the ESX-1320 twisted pair 
segment and the ESX-1380 multimode fiber optic segment to the network. 
It is recommended that the pre-installation test procedures in Section 3.8 
be performed prior to connecting either ESX model to the network.

The procedures for connecting segments to the ESX BRIM slot are 
detailed in the appropriate BRIM Installation Guide. 

To connect the ESX-1320 to the network, proceed to Section 3.9.1. To 
connect the ESX-1380 to a network, proceed to Section 3.9.2.

Before connecting a segment to the ESX-1320, check each end of the 
segment to verify wire crossover.

To connect a twisted pair segment to the ESX-1320, proceed as follows:

1. Refer to Figure 3-14. Connect the twisted pair segment to the module 

by inserting the RJ45 connector on the twisted pair segment into the 
desired RJ45 port on the module, Ports 1 through 12.

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 bridge port to 
bridge port).
