Model 7339 Switches to Secondary Line When No Data is Detected on Primary Line
October 7, 2013
For Immediate Release
Standards Laboratories (ESL), Cranston, RI, has just announced its new PathWay
Model 7339 CAT5e
10/100/1000BASE-T Full/Half Duplex RJ45 A/B Automatic Fallback Switch with
10/100 Base-T LAN Telnet Access and Graphical User Interface (GUI). The
Model 7339 shares a single port interface device connected to the COMMON port
among two other devices connected to the A and B ports. The GUI is
user-friendly. To connect to the switch from a workstation or computer with
access to the LAN that the Model 7339 LAN port is connected to, simple launch a
standard web browser and type in the appropriate IP address. The Java Applet
will be automatically uploaded from the switch upon connection. The switch is
easy to control with simple point and click operation.
When in automatic fallback mode, the unit monitors data
activity on ports A and B. If activity is lost on A, the unit checks for
data on Port B and in the presence of data, switches to position B.
The Model 7339 data switch maintains its connection to
port B until data activity is detected on port A, at which time the unit will
automatically return to the A position. If no data is present on either
port A or on port B, the unit will stay in the A position and continue to
monitor for data.
The user can override automatic fallback operation from the
front panel or GUI interface and operate the Model 7339 as an A/B switch. The
switch can be controlled from a 10/100 Base-T LAN Ethernet environment. Remote control Telnet command interface or a
Graphical User Interface (GUI) allow the user to control the switch position,
lockout the front panel operations and obtain switch status.
The switch ports are transparent to all data. All pins of
the RJ45 interface are switched. The switch interface meets CAT5e performance. All switched signals are passed via latching
copper contact relays that maintain their position and continuity in the event
of a power loss. Front panel LED’s display switch position, the switch mode
(automatic fallback or manual) and power status.
port connectors include (3) RJ45 (F) connectors labeled A, B and COMMON. The front
panel controls include a manual pushbutton that allows local switching. The
display includes (2) front-panel LEDs that indicate switch position and power
status. For remote control (1) RJ45 (F) connector on the rear panel accepts
10/100 Base-T LAN Access Ethernet and Graphical User Interface (GUI). The Model
7339 is configured in a slim rackmount design. The dimensions are 19” W x 1.75”
H x 10” D (48.3 x 4.4 x 25.4 cm). The switch weighs approximately 5.5 lbs (2.49
A Wide Range Power Module, Catalog No. 521895, makes this
switch ideal for worldwide applications. The module is CE and UL listed. The
unit is configured as a table mount configuration. This module supports
100VAC/240VAC, 50Hz/60Hz operation. The unit has an IEC 60320 C14 inlet.
