Management Ports; Network Topology - FibroLAN CTF6/M User And Installation Manual

A LED on the front panel of the unit reflects the status of the optional redundant power supply,
if installed. When the redundant power is operating properly, its LED is a steady green.
Both the redundant power supply and the main power supply can be "hot swapped". This
means that should either power supply fail, the failed unit can be removed and replaced with a
new power supply while the unit is operating, without network the operation being interrupted.
Each power supply has its own power cord. By connecting the two power cords to outlets on
separate power circuits, you increase the protection to your media converter from operational
failure should a power circuit fail.
AC Outlet
The unit does not have an ON/OFF power switch. Power is applied to and removed from the
system by connecting and disconnecting the power cable. When disconnecting power from the
unit, you should disconnect the power cord from the power source before disconnecting the
cord from the back panel of the unit.

Management Ports

These ports are in use whenever an FNM1612 SNMP management module is installed. When
the module is plugged in, these ports allow communication with the module in two ways. The
first is by means of the network, through one of the RJ45 ports connected either to a hub/switch
or to a workstation (one of the ports provides straight – the other cross connection). The second
is by using a terminal conected to the PS/2 (miniDIN) port, through the supplied cable (PS/2 to
DB9).
Using the management module with your CTF/M enables you to remotely view the status of the
device (see management appendix).
The FNM1612 module itself is plugged in through the rear panel of the device.

Network Topology

The value of the CTF6/12M Multichannel Media Converters is that they allow you to extend the
reach of your network and to interconnect widespread network devices and subnetworks into
one integrated network.
Figure 6 illustrates an example of a network that incorporates an CTF6/M unit to interconnect
dispersed network devices. At the top of the topology is an Fast Ethernet (dual speed) switch.
Six of the twisted pair ports on the switch are connected to the six twisted pair ports on the
CTF6/M media converter. Fiber optic cabling from the CTF6/M unit connects the media
converter to the switches, hubs, and workstation that comprise the network.
