Chii chinonzi POE Simba Pamusoro peEthernet? - Network Technology Guide
Simba pamusoro peEthernet (PoE) itekinoroji inoshandura mitambo yemanetiweki emazuva ano. Inobvumira data uye simba kuyerera kuburikidza netambo imwe yeEthernet. Izvi zvinoita kuti kubatanidza uye magetsi zvigadziriswe zvive nyore uye zvakanyanya kushanda munzvimbo dzakawanda.
PoE kiyi yekuseta network, ichipa iri nyore uye inokwanisika nzira yemagetsi zvishandiso. Izvi zvinosanganisira IP kamera, isina waya yekuwana nzvimbo, mafoni eVoIP, uye smart sensors.
PoE inobvumira Ethernet switch kana mamwe magiya emagetsi emagetsi zvakananga. Izvi zvinoreva kuti hapana kudikanwa kwemamwe magetsi masosi kana adapta. Inoita kuti kuseta kuve nyore, kudzikisa pasi panyonganiso, uye inowedzera kushanda zvakanaka kwetiweki, kunyanya uko magetsi emagetsi akaoma kuwana.

PoE Inoshanda Sei?
| PoE Standard | Maximum Power Delivery |
| 802.3af (PoE) | 15.4 watts |
| 802.3at (PoE+) | 30 watts |
| 802.3bt (PoE++) | 90 watts |
PoE Zviyero uye Zvikamu
IEEE 802.3af (PoE)
Iyo IEEE 802.3af standard, inozivikanwawo sePoE, ndiyo yekutanga kurova kukuru. Iyo inoita kuti zvishandiso zvikwire kusvika ku15.4 watts emagetsi, aine angangoita 12.95 watts yechishandiso pachayo.
IEEE 802.3at (PoE+)
Iyo IEEE 802.3at standard, kana PoE+, yakakwira simba kusvika pamakumi matatu watts. Izvi zvinoreva kuti midziyo yakaita sePTZ kamera uye isina waya yekuwana nzvimbo inogona kuwana simba rakawanda.
IEEE 802.3bt (PoE++ kana 4PPoE)
Iyo yazvino chiyero, IEEE 802.3bt, kana PoE++ kana 4PPoE, inoenda zvakatopfuura. Inobvumira kusvika ku90 watts emagetsi, ichiita kuti ive yakakwana kune yakakwirira-simba zvishandiso semarambi eLED uye magiya emaindasitiri.
Makirasi eMasimba uye Madiro Avo
PoE zviyero zvine makirasi emagetsi akasiyana. Aya makirasi anotangira Kirasi 0 kusvika Kirasi 8, rimwe nerimwe riine simba rayo. Heino tafura inoratidza masimba emagetsi ekirasi yega yega:
| Power Kirasi | Maximum Power at Power Source | Minimum Power at Powered Device |
| Kirasi 0 | 15.4 W | 0.44 W - 12.95 W |
| Kirasi 1 | 4 mukati | 0.44 W - 3.84 W |
| Kirasi 2 | 7 W | 3.84 W - 6.49 W |
| Kirasi 3 | 15.4 W | 6.49 W - 12.95 W |
| Kirasi 4 | 30 W | 12.95 W - 25.5 W |
| Kirasi 5 | 45 W | 25.5 W - 40 W |
| Kirasi 6 | 60 W | 40 W - 51 W |
| Kirasi 7 | 75 W | 51 W - 62 W |
| Kirasi 8 | 90 W | 62 W - 71 W |
Zvishandiso zvePoE: PoE Zvishandiso
Simba pamusoro peEthernet (PoE) tekinoroji ikozvino yakajairika mu network dzakawanda. Inoshandiswa mumhando dzakasiyana dzemidziyo uye masisitimu. Kubva kusimba redetembo pamusoro pemidziyo yeethernet kuenda kusimba rekunyengerera pamusoro pemaapplication eethernet, PoE yashandura mabatiro atinoita nekubatanidza zvikamu zvakasiyana zvesimba renhetembo pamusoro pemasystem ethernet.
Kumwe kushandiswa kukuru kwePoE kuri mukati IP makamera uye surveillance systems. Midziyo iyi inowana simba uye data kuburikidza netambo imwe yeEthernet. Izvi zvinoita kuti kuseta kuve nyore uye kunobvisa kudiwa kwemamwe magetsi masosi.
PoE yakakoshawo mukati Voice over IP (VoIP) mafoni. Inobatsira mafoni aya kushanda pamwechete zvakanaka mumahofisi. Izvi zvinoita kuti kutaurirana kuve nani uye kwakabatana.
PoE yakanaka kune isina waya yekuwana nzvimbo uye IoT sensors zvakare. Aya masimba edetembo pamusoro pemidziyo yeethernet anogona kusetwa chero kupi pasina kuda magetsi. Izvi zvinodaro nekuti PoE inotumira zvese data uye simba pamusoro peiyo Ethernet tambo. Yakanakira zvivakwa zvakangwara, nzvimbo dzeindasitiri, uye maIoT masisitimu.
| PoE-Powered Chishandiso | Application |
| IP Makamera | Kuongorora uye kuchengetedza masisitimu |
| VoIP Mafoni | Kutaurirana kwakabatana munzvimbo dzehofisi |
| Wireless Access Points | Wireless yekubatanidza muzvivakwa zvakangwara uye IoT network |
| IoT Sensors | Monitoring uye otomatiki mumaindasitiri uye ekutengesa marongero |
Zvakanakira Kushandisa PoE
PoE, kana Simba pamusoro peEthernet, inyanzvi yetiweki ine mabhenefiti akawanda. Inorerutsa kuisa uye inowedzera kushanda kwemagetsi. Izvi zvinoita kuti ive sarudzo yepamusoro yekugonesa zvishandiso mumanetiweki.
Imwe huru nhetembo simba pamusoro peethernet kubatsirwa ndeye kuendesa data nesimba kuburikidza netambo imwe yeEthernet. Izvi zvinoderedza clutter uye zvinoita kuti kuseta kuve nyore. Uyezve, poe simba rekushandisa kunoreva kushoma kushandiswa kwesimba, kuchengetedza mari mukufamba kwenguva.
Imwe nhetembo simba pamusoro peethernet mukana ndewayo flexibility. Midziyo inogona kuenda painodiwa, isingade magetsi. Uku kuchinjika kwakanakira kumisikidza isina waya yekuwana nzvimbo, IP kamera, uye VoIP mafoni.
Pakupedzisira, poe mutengo-kubudirira ikuwedzera kukuru. Iyo inochengetedza pakuisa uye kuchengetedza mitengo nekusada akasiyana masisitimu emagetsi. Izvi zvinoita kuti PoE inakidze kune ese marudzi emabhizinesi, makuru kana madiki.
Kushandisa PoE kunogona kuita kuti kuseta network kuve nyore, kunatsiridza mashandisiro emagetsi, uye kuchengetedza mari. Iyo yakangwara sarudzo kune akawanda maapplication.
