3.17.5 Connecting the Interface Cable
Step 1: Insert the SFP module into its corresponding slot.
Step 2: Locate the Rx and Tx fiber-optic interfaces on the module. Use two fibers to
connect the MIM-1POS to another device, with Rx to Tx and Tx to Rx.
Step 3: Check the LINK LED on the MIM-1POS panel: ON means the Rx link is present
and OFF means the opposite. Check the line in the second case.
Warning:
Because invisible laser radiation may be emitted from the aperture of an optical port
when no fiber is connected or the dust cap is removed, do not stare into the open
aperture.
Replace the dust cap when no fiber is connected to the optical port.

MIM-4FXS/MIM-4FXO/MIM-4E&M
3.18.1 Introduction
2/4-port voice subscriber circuit interface module (MIM-2FXS/MIM-4FXS) serves to
access and handle 2/4 channels of ordinary analog phone, fax, or AT0 loop trunk of
telephone exchange.
2/4-port voice AT0 analog trunk interface module (MIM-2FXO/MIM-4FXO) serves to
access and handle 2/4 channels of common user lines of telephone exchange.
2/4-port voice E&M analog trunk interface module (MIM-2E&M/MIM-4E&M) serves to
access and handle 2/4 channels of E&M analog trunks.
These modules make it possible to transfer voice signals over data communication
networks.
Caution:
When connecting a voice MIM, make sure that H3C Series Routers can be connected
to an IP network or other LAN.
