MODEL- USR997624          VENDOR- US ROBOTICS
     
FEATURES- Courier 24-Port PoE Smart Switch
       The latest addition to the USRobotics Courier business solutions 
        line, the 24-Port PoE Smart Switch, provides data connectivity and 
        DC power to Ethernet devices in difficult to reach locations. 
       Designed with flexibility and expandability in mind, it supports 
        variable power settings up to 15.4W on the 24 10/100 Mbps ports 
        (maximum total 170W), and has two Gigabit ports (for uplinks and 
        extending networking range). Simple to use web-based management 
        makes this an ideal solution for small and medium businesses. 
    Includes 24-Port PoE Smart Switch, Rack mount accessories (i.e. 
      brackets, screws), Power cables (North America, UK, Europe), Quick 
      Installation Guide, Documentation/Utility CD-ROM.
* DC Power Where You Need It
   - Save money by delivering DC power via Ethernet cabling 
   - Support for PoE priority settings so that high priority devices (eg. 
     IP Phones) stay powered in case of unexpected power drain allowing low 
     priority devices to be powered off if necessary.
   - Includes both over current and circuit sorting protection 
* Solid Manageability
   - Easy Web-based configuration from a Web browser anywhere on the 
     network.
      - Support for port-based VLAN 
      - Quality of Service (QoS) 
      - Port mirroring 
      - Specific port configurations (speed, duplex mode, and device flow 
        control).
   - Includes additional configuration and management utility (Windows 
     2000/XP compatible).
* Flexible Ethernet Connectivity
   - Supports Ethernet connections at speeds of 10/100 Mbps on 24 PoE ports 
     and 10/100/1000 Mbps on 2 Gigabit ports.
   - Auto-Speed Detection - each port automatically detects, and matches 
     the speed of connected Ethernet devices.
   - Auto-Switching eliminates the need for cross-over cables.
* Simple, Reliable Design
   - Metal case and efficient design enhance reliability 
   - Visual diagnostic LEDs 
   - Standard 19 inch rack-mount form factor 
* Non-Blocking
   - Overall throughput matches the total capacity of the switch ports (8.8 
     Gbps).
