High Speed Ethernet Extender |
Product Highlights
Use a single voice-grade twisted-pair cable to extend your network at
greater distances without forgoing speed or having to use CAT5e or fiber cabling.
Distances up to 6000 feet (1828.8 m).
Ideal for extending 10-/100-Mbps links to remote buildings, those beyond the
328-foot (100-m) limit of Ethernet.
Features
Offers data rates up to 50 Mbps in each direction for an aggregated
full-duplex speed of 100 Mbps.
Switch-selectable line rates—choose the optimal speed for a particular
application.
Asymmetric or symmetric operation.
Great for bandwidth-intensive applications, with performance approximating
that of fiber.
Interconnect remote devices or networks to a central LAN for videoconferencing,
VoIP calling, Ethernet bridging, or provisioning broadband triple-play (Internet,
TV, and telephone) services.
Simple to install, and there’s no configuration or complex cabling to deal
with.
Autodetects 10-/100-Mbps connections, autonegotiating full- or half-duplex.
Auto MDI-X detects the link’s pinning, so you can use straight or cross-pinned
cables.
Bridges LANs transparently, passing higher layer protocols. Also supports
802.1Q VLAN tagged and untagged traffic.
Configure each extender in the kit as a local or remote unit with a slide of a
switch.

PoE PD Switches |
Product Highlights
These compact Power over Ethernet (PoE) Powered Device (PD) switches are
perfect for your network’s edge.
Choose from a wide range of port options, including single-strand fiber.
Features
Use fiber ports to extend your network up to 100 kilometers (62 miles).
Use copper ports to increase network port density.
Single-strand fiber models transmit and receive on a single fiber, enabling
you to maximize use of your fiber infrastructure.
All copper ports are autosensing 10-/100-Mbps Ethernet with MDI/MDI-X.
One port supports PoE.
Feature a VoIP port for high-priority VoIP packets.
Diffserv/TOS IP packet prioritization on all ports for QoS prioritization.
Fiber ports provide notification of link loss at the far end of the fiber.
Include broadcast storm protection.
Support 1916-byte packet size.

Dual Secure Console Servers |
Product Highlights
Access up to 32 serial console ports securely over your Ethernet network.
RS-232 ports with an RJ-45 interface.
Features
Dual 10-/100-/100-Mbps Ethernet ports.
Optional dual power inputs.
Secure access to RS-232 serial console ports across your Ethernet network.
Dual Gigabit Ethernet ports plus optional dual power inputs for maximum
redundancy.
The PCI port supports a V.92 modem for emergency access in case of complete
network failure.
Features a powerful 400-Mhz, 750-MIPS, 32-bit processor.
Easy to manage through any Web browser or Telnet™.
Secured with 128-, 192- and 256-bit AES, 3DES, Blowfish, and CAST128, plus
ARCFOUR or ARCTWO data encryption across the LAN via SSH and SSL.
Advanced user authentication through RADIUS, TACACS+, LDAP, Kerberos, NIS, and
RSA.
Manageable through Windows® Device Manager, HTTP, HTTPS/SSL/TLS, SSH, or
Telnet.
Includes COMredirect software to provide true remote serial ports over an
Ethernet LAN.
Supports e-mail event notification.
Syslog support enables you to track system events for routine troubleshooting
and incident handling.
The sturdy steel chassis is only 1U high and can be front- or rear-mounted.
Built-in surge protection on all interfaces.

Heavy-Duty Edge Switches |
Product Highlights
Choose from versions for office, industrial, or outdoor environments.
Feature six copper ports to expand your network.
Tough steel case.
Support autonegotiation, so you can easily attach any 10- or 100-Mbps device.
Features
Hardened and Extreme versions available with AC or DC power supplies.
Two sets of LEDs enable you to see status information from the front, top, or
side.
Support VLAN tagging and spanning tree passthrough.
Include Link-Loss-Learn (LLL) feature for fast network recovery.
Unlike the Ethernet switches in your wiring closet or computer center, the
Ethernet switches at the edges of your network have to put up with the bumps,
the dirt, the dampness, and the temperature fluctuations that happen out in the
real world. This is where Heavy-Duty Edge Switches from Black Box come in.
These Heavy-Duty Edge Switches are tough, 6-port copper Ethernet switches that
enable you to expand your network even into harsh environments such as factory
floors or the outdoors. They’re robust, they’re easy to set up, and they’re
available with a vast array of power and durability options.
What‘s more, you can daisychain Heavy-Duty Edge Switches together indefinitely,
making them ideal for applications such as traffic signals where many switches
are needed over a long distance.

Back Office Switches |
Product Highlights
Provide enhanced QoS support for real-time applications.
Features
Two ports on each switch also support Gigabit fiber uplinks with an SFP
Optical Transceiver.
Port mirroring enables you to isolate network errors without disrupting data
flow.
Add a Gigabit fiber uplink with an SFP Optical Transceiver.
Port- and tag-based VLAN.
Bandwidth aggregration is ideal for high-volume communications.
Ports autosense for speed and autonegotiate for duplex.
