The location of a RFL 3000 4K-Series Switch is dependent on the physical layout of the
network. Typically the Switch is placed in a central wiring location where groups of
network devices need to be connected in order to communicate with each other. These
Switches are typically rack mounted in a wiring closet (see Section 3.3.2 below), but they
have rubber feet and can also be installed on a shelf or table top.
Locate an AC receptacle that is within six feet (2 meters) of the intended RFL
3000 4K-Series site. The rugged metal case of the RFL 3000 4K-Series will normally
protect it from accidental damage in a lab or workplace setting. Maintain an open view
of the front to visually monitor the status LEDs. Keep an open area around the unit so
that cooling can occur from the small fan on the left side, while the unit is in operation.

Media
The RFL 3000 4K24 Switches are specifically designed to support all standard Ethernet
media types within a single Switch unit. This is accomplished by using a family of Fiber-
port Modules (FKMs) which can be individually selected and configured per-port. See
Section 2.4 for a description of the FKMs.
The various media types supported along with the corresponding IEEE 802.3 and 802.3u
standards and connector types are as follows:
IEEE Standard Media Type Max. Distance Port Module

3.2.1 Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a FKM with ST-type fiber
connectors. This procedure applies to ports using a FKM-MST or FKM10-MST.
