Uplink/downlink Fault Detection Is Provided By Linkalert™. Autosensing Port Configuration. Full- And Half-duplex Operation. Universal, Autosensing Power Supply. Also Available In 6-port, Single-mode, Sc, And 100base-tx To 100base-fx Models. Connect Ethernet Segments To Fiber Segments Without Using Crossover Cables. With A Black Box Autocross Media Converter, You No Longer Have To Deal With Mismatched Transmit And Receive Cable Pairs. This Converter Contains A Switch That Senses The Type Of Circuit Connected To The Utp Port And Automatically Configures The Port To Match. Because The Utp Side Is Autosensing To Mdi/mdi-x, You Can Use Either A Straight Or Crossed Cable To Connect A Switch Or Nic. The Converter Features Linkalert™, Which Monitors 100% Of Physical Uplink And Downlink Failures And Alerts The Network If The Transmission Fails. This Ethernet Version Of The Autocross Media Converter Is Not Compatible With Autosensing Devices (for Example, A 10-/100-mbps Hub); It Only Works With Standard 10-mbps Devices. Use The Autocross Media Converter Up To 100 Meters (328 Ft.) On The Utp Link And Up To 2 Kilometers (1.2 Mi.) On A Multimode Fiber Link.

wallmount Hardware Kit For Flexpoint Media Converters

Operates Half- Or Full-duplex, Point-to-point, And Transparent To Speed. Attaches Directly To Equipment Ports Or Between Two Cables.

the Pro Switching System 2u Is An Intelligent Ganged Switching System Consisting Of An Ultra-compact 2u 18-slot Chassis And A Selection Of A/b Switching, Controller, And Power Supply Cards. Controller Cards Take Up Only One Slot, And Power Cards Take Up One Slot Or Two Slots For Redundancy, Leaving You With 13 - 15 Slots For A/b Switch Cards. All Occupy One Slot, Except For The Db25 Cards, Which Require Three Slots. Local And Remote Controlthe Advanced Design Of This System Gives Incredible Operational Flexibility And Performance. Switch One Card Individually Or Switch The Entire Chassis Through A Controller Card. You Will Need One Controller Card Per Rack Chassis. If You Plan To Daisy Chain Multiple Chassis, The Controller Card In The First Chassis Controls The Entire System.you Can Choose An Rs-232 Only Controller Card, Which Enables You To Gang Switch Via The Manual Toggle Switch Or With Serial Commands, As Well As An Rs-232/ethernet (snmp) Controller Card, Which Enables You To Switch The Chassis From Anywhere Via An Rs-232 Or Ip Connection. If You Want To Extend Rs-232/ip Control To A Second Daisy-chained Pro Switching System Chassis, Order The Snmp Expansion Controller Card. This Enables You To Send Hardware Control Signals And Control The Daisy-chained System With Rs-232 Messages Through The Rs-232/ethernet (snmp) Controller Card.secure And Fallback Switching.for Fail-safe Operation, All The Cards (except Those Noted) Use Proprietary Latching Or Micro-mirror Relay Switching Technology - Which Means Data Can Continue To Pass Through Even If The Power Has Been Cut Off. Because The Cards Perform Layer 1 Switching, The System Operates Independently Of Data Rates, Protocols, Formats, Or Signal Levels.the Non-latching Fiber Cards Fall Back To A Port C (chassis) To Port A Connection When The Power Fails. When Power Is Restored, The Non-latching Switch Card Reconnects Port C To The Originally Selected Port (a Or B). These Types Of Cards Are Typical When You Want A Fallback Or Failover Connection During Power Outages.each Chassis Also Has A Keyed Switch So You Can Enable/disable Manual Switching From The Front-panel Toggle Switches.control Power.to Power Your Chassis, Order One Or Two External Power Supplies, And The Power Adapter Card. For Backup Power, Add A Redundant Power Supply Card.

Protection For Rs-232 And Token Ring. Low Shunt Capacitance To Reduce Signal Loss. State-of-the-art Avalanche Diode Technology.

FIBER OPTIC A/B/C/D SWITCH W/ST CONNECTORS LATCHING

Switch Latches Mirror Movement Mechanically Into A Selected Position And Holds It There Without The Need For Continuous Electrical Power. Connect A Single Workstation To Two Or More Networks Or Remote Devices. Simple To Use. To Route Signals, Just Turn A Knob On The Front Panel. Ideal For Government, Healthcare, Financial, Or Other Applications Where A Private, Data-sensitive Network Connects To A Publicly Accessible Network. For Reliable Switching In Mission-critical Environments, The Micro-mirror Is Bonded To Precise Positioning Servers. Air-gap Isolation Provides A Physical Break In The Circuit Connection. Operates Transparently To Signal Rates, Formats, And Wavelengths, And Doesn''t Require An Upgrade When Your Data Protocols Change Or Speeds Increase. Works With 9-/125-micron Single-mode Fiber Cable. Universal 100-240-vac Power Supply. There''s A Reason Why This Type Of Manual Switch Continues To Be The Switch Of Choice For Networking Professionals Everywhere: This Tried-and-true Optical Switch Performs As Promised Year After Year. This Type Of Switch Is Reliable Because It Uses A Micro-mirror Instead Of Electronics To Route Data Signals From One Fiber Optic Port To The Next. And Unlike Conventional Electronic Switches, There Are No Complex And Vulnerable Electronic Circuits To Monitor And Protect From Intrusion, Component Failure, Or Interference. Plus The Optical Mirror Movement On This Latching Switch Maintains The Selected Position Even When There''s A Power Failure.

durable And Reliable. Tested To 1,000,000 Cycles Manual Control Of The Switch Port Supported Through A/b Push Button On The Front. Can Be Switched Remotely Via Rs-232 Or Dry Contact.
