Physical
Layer Switch 32 Port LX2500 2.5 Gb/s
Fiber Patch
Panel Management Overview
The 32 Port Physical Layer Switch LinkXchange LX2500 is a multi-purpose,
non-blocking 32-port crosspoint switch for digital signals at speeds up
to 2.5 gigabits per second (Gbps). Any of its 32 outputs can be connected
to any one of its 32 inputs.
The protocol or structure of data routed through the switch is ignored
by the LX2500 and is unaltered by its passage through the switch. This
allows the LX2500 to be used with many different types of networks and
signals - Fibre Channel, Serial FPDP, Sonet, HDTV, GigE.
A single 32 port physical layer switch holds up to eight port cards. Each
port card provides the physical ports for four input-output pairs. While
the crosspoint switch itself can operate from DC to 2.5 Gbps, different
types of port cards impose different limitations on the range of data
rates or the data format that they will pass.
The
LX2500 is packaged in a rack-mountable enclosure that houses one or two
LX2500 switches. Port cards can be specified as a part of the LX2500 or
ordered separately. A version of the LX2500 with hot-swappable dual redundant
power supplies is also available.
Hardware
Features
* Up to 32 non-blocking media-specific I/O ports
* Up to 2.5 Gbps/port baud rate (port card dependent)
* 80 Gbps total bandwidth
* Support for multiple point-to-point, loop, and multicast topologies
* Flexible automatic I/O Port fault isolation
* Multiple media options
* Hot-swappable port cards
* Out-of-band control through an RS-232 port or Ethernet
* Can be controlled remotely via telnet or web browser
User
Control Interface
The LX2500 is controlled through an RS-232 or an Ethernet port. The RS-232
port offers a command line interface that allows a user to configure and
receive status information from the LX2500. The Ethernet port allows users
on a network to control the LX2500 using the command line interface (via
Telnet) or a web browser.
The
user-control interface has these features:
* On-line help for each command
* Configurable status display
* Configurable alarms (log messages and beeps)
* Configurable fault isolation (bypassing and/or alternative source attachment)
* Automatic restoration of the last configuration at power up
* No user intervention required at startup
* Four saved configurations
* Multiple standard configurations
The
LX2500 control panel contains the power switch, reset button, RS-232 and
Ethernet connectors, and some indicator lights. The LX2500 port cards
each contain status indicators for their ports. See the individual port
card descriptions for details. In addition to the interface ports, the
LX2500 has a "Heartbeat" indicator, which flashes periodically
to indicate that the LX2500's embedded controller is functioning properly,
and a Reset pushbutton to reset the controller.
Operation The LX2500 has four main functions: 1. Route signals from port
card inputs to the selected port card outputs. 2. Provide an out-of-band
command line interface to the user. 3. Provide status and alarm information
to the user. 4. Provide fault isolation when required. Each port's output
may be connected to any port's input or turned off. This connection may
be unconditional, or it may be contingent upon which ports are active.
Any number of outputs may be connected to a particular input. Connecting
an output to an input does not disrupt the signals to any other outputs
that are already connected to that input.

Specifications
Order Number |
Description |
| LX2500 Units | |
| FHS3-xxxxxxxx-0 | Single LX2500 |
| FHS3-xxxxxxxx-1 FHS3-xxxxxxxx-21 |
Dual LX2500. Both numbers must be ordered together in order to specify port cards or filler plates for all 16 slots. |
| FHS3-xxxxxxxx-2 FHS3-xxxxxxxx-26 |
Dual LX2500 with redundant power supplies. Both numbers must be ordered together. |
| The LX2500 is available as one or two independent switches in a rack-mountable enclosure. These are shown in the LX2500 UNITS section of the table. For each LX2500 part number, the "xxxxxxxx" field specifies the port cards that are to be installed in the LX2500's eight slots. From left to right, the x's specify the cards for slots one through eight. For slots where a "0" is specified, a blank filler plate is installed instead of a port card. Values for "x" for each type of port card are shown in the LX2500 PORT CARD section of the table. | |
