Physically the connection between the COM3 port on the Multicon back plane and the Flashlink
Compact units is performed using a Shielded Twisted Pair (STP) Cat5 cable.
Note: To avoid any ground issues with connecting a Multicon in an N-
BOX to a Flashlink Compact unit it is required to use Shielded Twisted Pair
(STP) Cat5 cables for interconnecting the COM3 port on the Multicon
with the Flashlink Compact units.
Multicon in an N-BOX will always appear in frame 0 in the web interface, but you are able to set
the slot position using the switch on the back of the N-BOX (see picture below). Please make sure
that there is no address overlap between the Multicon in an N-BOX and any Flashlink cards in the
system. The safest option is to not configure any connected Flashlink frames of Flashlink Compact
units to use frame address 0. For more information about Flashlink frame and Flashlink Compact
addressing please refer to respective user manuals.
To use the external RS422 Flashlink bus (COM3), Multicon must be configured to use the external
instead of the default internal bus using the Nevion Configurator. The screenshot below shows
how to change the setting from internal to external bus connection. The dialog is opened by per-
forming the following steps:
• Open the system including the Multicon controller in Nevion Configurator
• From the System Overview page, right click on the Multicon Controller and select Prop-
erties
Note: The option to select internal or external bus connection is only
available if the Multicon has been booted in a normal Flashlink frame
first with at least one Flashlink card present. This is always the case for
Multicon cards delivered by Nevion, as it is part of standard test procedures, but
may not be the case for field upgraded units. To overcome this problem please boot
the Multicon card in a Flashlink 2RU frame first with one or more Flashlink cards
to be able to set the setting to external bus connection.
