RJ-45 ports provide twisted pair segment connections, with N-way auto-
negotiation and switching capability per port.
Full-duplex or Half-duplex operation, auto-sensing
All fiber and RJ-45 (copper) ports are capable of half- or full-duplex,
individually selected. All RJ-45 ports support 10/100 auto-negotiation.
Standard (ports in front) or Reverse (ports in rear) rack mounting
The 4K24 is offered with ports and LEDs in the front, or in a “reverse”
package with LEDs in front and all Ethernet and power cables in the rear. As
a special feature of the 4K24 Reverse, LEDs are both front and rear. .
Standard 19’ rack mount brackets are included, while ETSI and 23” Telco are
optional.
Plug-and-Play installation for high performance switching
RFL 3000 4K24 Switches are self-learning for node addresses. They can be
placed into operation without complex set-up procedures, even in large
networks. They operate transparent to system software.
Standard AC power input, -48VDC, 24VDC, or 125VDC is available
Standard AC power input is IEC plug, auto-ranging for worldwide use. For
special applications, models with –48VDC, 24VDC, or 125VDC are available.
Dual source DC input can also be selected and configured on the –48VDC,
24VDC, and 125VDC input models.
Extended Temperature Operation
The RFL 3000 4K24 has been tested for operation at temperatures of –5’C to
55’C. NEBS-certified models have been tested to a greater range per
NEBS Level 3 requirements.
2.4 Applications
RFL 3000 4K24 Switches offer high performance flexibility, and are easily used
in a variety of applications including client/server computing, performance upgrades of
departmental networks, and collapsed backbone applications. The Dual-Speed
characteristic of the 4K24 Switches enables them to inter-connect a series of subnets (one
subnet per 4K-Series Switch port) in a LAN traffic center. The subnet connections may
be via either optional fiber or twisted pair cabling, and may be 100Mbps or 10 Mbps
speed and full-or half-duplex mode. The 24-ports non-blocking switching capability of
RFL 3000 4K24’s support larger networks with multiple workgroups.
The mixed-media capability is ideal for upgrading existing Ethernet LAN
networks, where existing cabling must be accommodated. The fiber-built-in media
capability is ideal for integrating future-proof fiber cabling into the LAN structure.
