ACC-5595-208 350-805595-208N Intellgent SNMP Hub

Description

ACC-5595
2 Gb/s Reflective Memory Hub Assembly
Features
• For use with GE Intelligent Platforms 5565
Reflective Memory network of products
• Provides up to eight ports using small form
factor pluggable (SFP) transceivers
• Hub assemblies can be cascaded with a
maximum of 256 nodes
• Automatically bypasses defective or disconnected nodes in a fiber-optic network
• Automatic bypass can be optionally
controlled by the loss of signal or by the
loss of sync pattern
• Each port regenerates the serial optical
signal, eliminating link losses and reducing jitter
• Configurable for use with cables up to
10 km in length
• 10BaseT Ethernet TCP/IP port for remote
access and control
• RS232 port for local access and control
• Optional 19 – inch 1U rack mount or
desktop enclosure
• Internal universal power supply
• Dark on Dark option turns off the board’s
transmitter if the receiver does not detect
a signal (available for firmware versions
02.00 and later)
The ACC-5595 is a managed hub designed
to operate with the GE Intelligent Platforms
5565 family of Reflective Memory real-time
network products. The Reflective Memory
hub can automatically bypass ports when
it detects a loss of signal or the loss of valid
synchronization patterns, allowing the other
nodes in the network to remain operational.
Since the optical ports are implemented
with small form factor pluggable (SFP) transceivers, only the required ports need to be
populated. The ACC-5595 SFP transceivers
can be a combination of either multimode
(short distance) or single-mode (long distance) transceivers. This feature permits a
cost saving in small networks as well as system optimization. For larger networks, several
ACC-5595 assemblies can be cascaded,
permitting a managed hub array with up to
256 nodes. Each port regenerates the serial
optical signal, eliminating the problems with
insertion losses and cable attenuation. Signal
regeneration also reduces jitter. The RS232
port gives you the ability to monitor and control your Reflective Memory network through
a simple PC serial port. The Ethernet port
feature allows you to monitor and control
the hub from great distances through a local
area network (LAN) or via a Web browser.
As an option, the ACC-5595 can be configured
as a 19-inch 1U rack-mountable enclosure or
as a desktop enclosure. The universal power
supply permits operation with nearly any
international power standard.
The ACC-5595 automatically bypasses ports
when the absence of valid synchronization
patterns is detected. Three LEDs, adjacent to
each port, provide a visual indication of the
port status. Additional status indications and
modes of operation are available through
either the serial port or the Ethernet port.
Status information includes the detection of
installed transceivers, the detection of signal
(light), the detection of valid synchronization patterns and the port operation speed
(2 Gb/s). Control registers allow the channel
bypass to be based on the absence of a single valid synchronization pattern or multiple
synchronization patterns. A bypass can also
be based simply on the loss of a signal (light).
In addition, each port can be manually forced
either active or bypassed regardless of the
status indicators.
An additional control register permits the transmitter of any port to be manually disabled.
