Warning:
Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which
are connected to lasers. To protect your eyes against radiation harm, never stare into
an open fiber-optic port.
Step 1: Insert the SFP optical module into its corresponding slot.
Step 2: Locate the Rx and Tx ports of the MIM-1GEF/MIM-2GEF interface. Connect
them to another device with two optical fibers: Rx to Tx and Tx to Rx.
Step 3: Power on the router and check the behavior of the LINK LED on the
MIM-1GEF/MIM-2GEF panel. ON means an Rx link is present and OFF means the
opposite. In the latter case, check the line status.
3.4 MIM-2SAE/MIM-4SAE/MIM-8SAE Module
3.4.1 Introduction
MIM-2SAE/MIM-4SAE/MIM-8SAE stands for 2/4/8-port enhanced high-speed
synchronous/asynchronous serial interface module. In terms of function, SAE modules
are the same as SA modules except that SAE modules support more protocols, for
example, RS449, X.21, and RS530.
3.4.2 Interface Attributes
The interface attributes of SAE modules are given in the following table:
