Whitebox PoE Switch 18

2) The equipment is tested for high temperature aging before delivery to ensure steady and reliable operation under harsh environments.

3) The switch adopts multiple mechanisms internally to effectively resist violent fluctuation of network voltage and lightning strikes.

4) The operation and maintenance personnel can configure and control the switch and detect its status at any location through network management software.

• Technical Features
  • POE power supply function complying with 802.3af standards;
  • POE power supply function can manage and monitor status through network management software;
  • POE power supply function can manage priority of port power supply to ensure the key equipment can obtain power preferentially;
  • It has powerful network management software;
  • It uses a special configuration interface which can conveniently and clearly configure;
  • It can manage equipment and monitor its status through Ethernet;
  • Network management information can pass through the router and firewall;
  • It uses a large database to perform date query and storage;
  • It has powerful database restore function;

• Network management information of the switch can greatly improve security for configuring and controlling the switch, and avoid illegal operation through double encryption;
• POE power supply can provide a maximum power of 15.4W for each port, and can manage POE power supply function and monitor the status through the network management software;
• POE power supply function for port can be randomly turned on or off as required;
• It can manage port power supply priority, namely, when power consumed by PD equipment is larger than total power provided by PSE, it preferentially provides power for the key equipment; it obtains priority ranking in accordance with port number, and priority with a smaller port number can be provided with power preferentially; Power supply priority is grouped into PORT1?PORT12 and PORT13?PORT24 as in the equipment; each group can provide a maximum power of 150W; the equipment will enable the power supply priority management function when total power provided externally by each group of port is larger than 140W to prevent the equipment from damaging due to overload, and at that time, the equipment will automatically shut down the port with the lowest power supply priority to ensure reliable power supply of the port with higher power supply priority;
• For the group of PORT1 ? PORT12, power supply priority is from PORT1 to PORT12, decreasing from high to low in turn; For the gourp of PORT13?PORT24, power supply priority is from PORT13 to PORT24, decreasing from high to low in turn;
• Note: please connect the key equipment needs power supply of Ethernet with the port of the equipment with higher power supply priority;
• It has power control function; the equipment will not allow new load when total power of all loads exceeds power normally provided by PSE to ensure power of the equipment will not be damaged due to overload, and even there is newly connected load, the equipment will not supply power for it, and the indicating lamp on the panel will slowly flash (lighting for two seconds and extinguishing for one second) to indicate the operation personnel;
• It can automatically detect connections of PD equipment and supply power for it;
• It can display power flow and power of current port in real time;
• Each port has thermal shutdown function to prevent the equipment from damaging due to high temperature;
• Each port has over-current protection function to prevent the equipment from damaging due to short-circuit;
• Each port has under-voltage/overvoltage protection;
• All said functions can be monitored in real time through the network management software to greatly facilitate fault monitoring and maintenance of the equipment;
• The equipment has bare machine mode and working mode a) Bare machine mode: ordinary switch mode, the equipment only responses to commands of bare machine configuration software; b) Working mode: works in accordance with configuration information; the equipment only communicates or responses to the reported network management commands and equipment status only through Uplink;
• It can configure port working mode, including: self-adaption switch, rate mode, duplex mode, back pressure switch, input and output bandwidth, MAC address study switch, broadcast storm suppression switch, port and VLAN priority switch, port mirror setting, port suspension,PVID; It supports VLAN settings of two modes: VLAN based on port and VLAN based on 802.1Q;
• It can set reorder queue of priority;
• It can use IGMP Snooping;
• The equipment supports relay settings of three groups of ports;
• It can perform security setting for IP address or TCP/UDP port;
• It supports intersecting line/through line self-adaption to facilitate installation of the equipment;
• Products of the series can store the newest configuration information, and every time when the equipment is electrified, the used settings shall be the same, and data storage time will not shorter than 10 years;
• The switch is stored with a duplication of data base of the network management server, so it can rebuilt data base of the network management server at any time;
• It can remotely upgrade network management software of bottom layer through Ethernet to avoid upgrading risk after equipment deployment;
• The switch can return to bare machine mode from working mode conveniently, to facilitate redeployment of the equipment;
• The equipment is good-looking and can be installed conveniently
