PANELS & INSTALLATION
2.2 LAN Connections
Front of unit
Depending on the model that you purchased, there are 16 or 8 shielded RJ-45 that provide LAN connection to the
Switch. On the IFS Series , these provide Ethernet for 10/100M connection. On the IGS Series , these ports are
10/100/1000M. Each of these LAN ports has associated LEDs which indicate the active link state and the detected
speed of the interface. A green indicates a link and a speed of 100M, while amber color indicates a link and speed of
1000M.
2.3 Fiber Connections
Front of unit
The IFS/IGS Series utilize SFP modules for fiber transmissions. Each of the fiber ports has an associated status LED
to indicate the presence or absence of fiber link and will also flash when there is Ethernet activity on the port. Each of
three SFP cages may insert any standard SFP module and be configured for 100M or 1000M operation. By having a
third fiber port, these devices can be used in a ring or linear topology while still having a third port for a fiber branch.
This makes these units extremely flexible when compared to other brand devices which have only two fiber ports.
Within the management interfaces of the IFS/IGS Series, the fiber ports are numbered after the LAN ports. So,
those fiber ports are seen as ports 17 ~ 20 or 9 ~ 20 by the internal switch and as viewed in management.
