Abstract
The invention provides a POE (power over Ethernet) switch port setting power limiting value validating method. The method comprises the following steps of first examining whether the POE switch port is opened or not, closing the port if the POE switch port is opened, and configuring the scalar quantity to be 1; setting a power limiting value of the port when the POE switch port stays at the closing state; judging whether the scalar quantity is 1 or not, delaying a period of time if the scalar quantity is 1,to show that the port stays at the closing state, then opening the port so that the setting of the limiting value is effective at the moment, and ending and returning. The POE switch port setting power limiting value validating method is simple to operate, and the setting of the power limiting value of the POE switch port can successfully take effect.
Description
Technical field
The present invention relates to a kind of method of the POE of configuration switch ports themselves, relate in particular to a kind of method of the POE of configuration switch ports themselves power limit.
Background technology
POE(Power over Ethernet, Power over Ethernet) refer to that in the time of for some IP-based terminal transmission data-signals, kind equipment provides direct current supply for this reason in the situation that existing Ethernet Cat.5 wiring architecture does not make any changes.
For example, with the switch of POE function, can power to accessing the offered load equipment of its port, if its internal circuit characteristic conforms IEEE802.3af/at codes and standards, and the power of its consumption is not more than the power limit that this port can provide.
Each POE port has the maximum power limit value that can export load, if the power of load consumption has surpassed this power limit, power overload will occur this port, stops load supplying, and this belongs to a kind of self-protection behavior of POE switch.So, be necessary the port of POE switch that power limit is set, to prevent load supplying.But there is the infirm problem of POE switch ports themselves power limit that arranges in existing technical method.
Summary of the invention
The technical problem that the present invention need solve is to provide a kind of POE switch ports themselves simple, that can make port power limit arrange to come into force smoothly power limit take-effective method is set.
For solving above-mentioned technical problem, the present invention has designed a kind of POE switch ports themselves power limit take-effective method has been set, and it comprises the following steps:
Step 1: check whether POE switch ports themselves is opened, if opening, close port, and to configure scalar be 1, then perform step 2; If not opening, directly perform step 2;
Step 2: the power limit that port is set;
Step 3: judge whether scalar is 1, if 1, enter step 4, otherwise finish to return;
Step 4: time delay a period of time, then open port, finish to return.
As the present invention, further improve, described power limit is 32W.
As the present invention, further improve, described a period of time is at least 50 milliseconds.
It is simple to operate that POE switch ports themselves of the present invention arranges power limit take-effective method, can make the power limit of POE switch ports themselves arrange smoothly and come into force.
Accompanying drawing explanation
Fig. 1 is the flow chart that POE switch ports themselves of the present invention arranges power limit take-effective method.
Embodiment
In order to make relevant technical staff in the field understand better technical scheme of the present invention, accompanying drawing below in conjunction with embodiment of the present invention, technical scheme in embodiment of the present invention is clearly and completely described, obviously, described execution mode is only the present invention's part execution mode, rather than whole execution modes.
The invention provides a kind of POE switch ports themselves power limit take-effective method is set, can make the power limit of POE switch ports themselves arrange smoothly and come into force.
As shown in Figure 1, POE switch ports themselves of the present invention arranges power limit take-effective method and comprises: first check whether POE switch ports themselves is opened, if opening, and close port, and to configure scalar be 1, then carry out next step; If not opening, in closed condition, also carry out next step.At POE switch ports themselves, during in closed condition, the power limit of port is set, general power limit is 32W.Judge again whether scalar is 1, if 1, represent that port is in closed condition, guarantee that port is to be under closed condition to carry out the step of power limit is set, then continue next step; Otherwise, represent that port, in non-closed condition, finishes to return, no longer continue next step.After setting up, then time delay a period of time, then open port, now arrange and come into force, finish to return.
In embodiments of the present invention, at least 50 milliseconds of a period of times of delay.If be less than this time, the power limit that arranges of port may not come into force.
Below only expressed one embodiment of the present invention, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
Claims (3)
1. POE switch ports themselves arranges a power limit take-effective method, it is characterized in that, comprises the following steps:
Step 1: check whether POE switch ports themselves is opened, if opening, close port, and to configure scalar be 1, then perform step 2; If not opening, directly perform step 2;
Step 2: the power limit that port is set;
Step 3: judge whether scalar is 1, if 1, enter step 4, otherwise finish to return;
Step 4: time delay a period of time, then open port, finish to return.
2. POE switch ports themselves according to claim 1 arranges power limit take-effective method, it is characterized in that, described power limit is 32W.
3. POE switch ports themselves according to claim 1 arranges power limit take-effective method, it is characterized in that, described a period of time is at least 50 milliseconds.
