He aha ka POE Power Over Ethernet? - Alakaʻi ʻenehana Pūnaewele
He ʻenehana hoʻololi pāʻani ʻo Power over Ethernet (PoE) no nā pūnaewele hou. Hāʻawi ia i ka ʻikepili a me ka mana e holo ma hoʻokahi kelepona Ethernet. ʻO kēia ka mea e maʻalahi ai ka hoʻohui ʻana a me ka mana o nā mea hana ma nā wahi he nui.
ʻO PoE ke kī i ka hoʻonohonoho pūnaewele, e hāʻawi ana i kahi ala maʻalahi a maʻalahi i nā mana mana. Loaʻa kēia i nā kāmeʻa IP, nā wahi kelepona ʻole, nā kelepona VoIP, a me nā ʻike akamai.
Hiki iā PoE ke hoʻololi pololei iā Ethernet a i ʻole nā mea uila uila ʻē aʻe. ʻAʻole pono kēia i nā kumu mana hou a i ʻole nā mea hoʻololi. E maʻalahi ka hoʻonohonoho ʻana, e hōʻemi i ka ʻino, a hoʻonui i ka pono o ka pūnaewele, ʻoi aku ka paʻakikī o nā puka mana.

Pehea ka hana ʻana o PoE?
| PoE Kūlana | Hoʻouna mana kiʻekiʻe |
| 802.3af (PoE) | 15.4 watts |
| 802.3at (PoE+) | 30 watts |
| 802.3bt (PoE++) | 90 watts |
Nā Kūlana a me nā Hoʻohālikelike PoE
IEEE 802.3af (PoE)
ʻO ka maʻamau IEEE 802.3af, i ʻike ʻia ʻo PoE, ʻo ia ka mea nui mua. Hāʻawi ia i nā polokalamu e piʻi i ka 15.4 watts o ka mana, me ka liʻiliʻi he 12.95 watts no ka mea ponoʻī.
IEEE 802.3at (PoE+)
ʻO ka IEEE 802.3at standard, a i ʻole PoE+, ua hoʻonui i ka mana i 30 watts. ʻO ia ke ʻano o nā mea e like me nā kāmela PTZ a me nā wahi ala ʻole hiki ke loaʻa ka mana hou aʻe.
IEEE 802.3bt (PoE++ a i ʻole 4PPoE)
ʻO ka maʻamau hou loa, ʻo IEEE 802.3bt, a i ʻole PoE++ a i ʻole 4PPoE, ʻoi aku ka nui. Hāʻawi ia i ka 90 watts o ka mana, e hoʻomaʻamaʻa maikaʻi ia no nā mea mana kiʻekiʻe e like me nā kukui LED a me nā mea hana ʻoihana.
Nā Papa Mana a me kā lākou mau kikoʻī
Loaʻa i nā kūlana PoE nā papa mana like ʻole. Loaʻa kēia mau papa mai ka Papa 0 a i ka Papa 8, kēlā me kēia me kona ʻano mana ponoʻī. Eia kahi papa e hōʻike ana i nā kikoʻī mana no kēlā me kēia papa:
| Papa Mana | Mana Kiekie ma ke Puna Mana | ʻO ka mana liʻiliʻi ma ka mea hana mana |
| Papa 0 | 15.4 W | 0.44 W - 12.95 W |
| Papa 1 | 4 in | 0.44 W - 3.84 W |
| Papa 2 | 7 W | 3.84 W - 6.49 W |
| Papa 3 | 15.4 W | 6.49 W - 12.95 W |
| Papa 4 | 30 W | 12.95 W - 25.5 W |
| Papa 5 | 45 W | 25.5 W - 40 W |
| Papa 6 | 60 W | 40 W - 51 W |
| Papa 7 | 75 W | 51 W - 62 W |
| Papa 8 | 90 W | 62 W - 71 W |
Noi o PoE : PoE Devices
He mea maʻamau ka mana ma luna o Ethernet (PoE). nui nā pūnaewele. Hoʻohana ʻia i nā ʻano mea like ʻole a me nā ʻōnaehana. Mai ka mana poe ma luna o nā polokalamu ethernet a hiki i ka mana poe ma luna o nā polokalamu ethernet, ua ho'ololi 'o PoE i ko mākou mana a ho'ohui i nā wahi like 'ole o ka mana poe ma luna o nā pūnaewele ethernet.
Aia kekahi hoʻohana nui o PoE Nā kamepiula IP a me nā ʻōnaehana nānā. Loaʻa i kēia mau mea mana ka mana a me ka ʻikepili ma o hoʻokahi kaula Ethernet. He mea maʻalahi kēia i ka hoʻonohonoho ʻana a hoʻopau i ka pono o nā kumu mana hou.
ʻO PoE ke kī nui Nā kelepona leo ma luna o IP (VoIP).. Kōkua ia i kēia mau kelepona e hana maʻalahi i nā keʻena. ʻOi aku ka maikaʻi o ke kamaʻilio ʻana a me ka lokahi.
Maikaʻi ka PoE no nā wahi komo ʻole a me nā mea ʻike IoT pū kekahi. Hiki ke hoʻonohonoho ʻia kēia mana poʻo ma luna o nā polokalamu ethernet ma nā wahi āpau me ka ʻole o ka pono o nā puka mana. No ka mea, hoʻouna ʻo PoE i ka ʻikepili a me ka mana ma luna o hoʻokahi kelepona Ethernet. He kūpono ia no nā hale akamai, nā wahi ʻoihana, a me nā ʻōnaehana IoT.
| Mea Mana PoE | Palapala noi |
| Nā Kāmeʻa IP | Nānā a me nā ʻōnaehana palekana |
| Kelepona VoIP | Kūkākūkā lokahi ma nā wahi keʻena |
| Nā Lae Komo ʻole | Hoʻohui ʻole i nā hale akamai a me nā pūnaewele IoT |
| Nā mea ʻike IoT | Ka nānā ʻana a me ka automation i nā ʻoihana ʻoihana a me nā ʻoihana |
ʻO nā pono o ka hoʻohana ʻana i ka PoE
ʻO PoE, a i ʻole Power over Ethernet, he ʻenehana pūnaewele me nā pono he nui. Hoʻomaʻamaʻa ia i ka hoʻokomo ʻana a hoʻonui i ka pono o ka mana. ʻO kēia ka mea i koho maikaʻi loa no ka hoʻohana ʻana i nā polokalamu i nā pūnaewele.
ʻO kekahi mana nui o ka poepoe ma luna o ka pono ethernet ka hāʻawi ʻana i ka ʻikepili a me ka mana ma o hoʻokahi kaula Ethernet. Hoʻopau kēia i ka clutter a maʻalahi ka hoʻonohonoho. Eia kekahi, ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ka ikehu, mālama kālā i ka wā lōʻihi.
ʻO kekahi mana poʻo ma luna o ka ethernet pono ʻo ia hikiwawe. Hiki i nā mea hana ke hele i kahi e pono ai lākou, me ka ʻole o nā puka mana. He mea maikaʻi kēia maʻalahi no ka hoʻonohonoho ʻana i nā wahi komo uea, nā kamera IP, a me nā kelepona VoIP.
ʻO ka hope, poe kumu kūʻai he mea hoonui nui. Mālama ia i ka hoʻokomo ʻana a me ka mālama ʻana i nā kumukūʻai ma o ka pono ʻole ʻana i nā ʻōnaehana mana kaʻawale. ʻO kēia ka mea e ʻoluʻolu ai ka PoE i nā ʻano ʻoihana āpau, nui a liʻiliʻi paha.
Hiki i ka hoʻohana ʻana iā PoE ke maʻalahi i ka hoʻonohonoho pūnaewele, hoʻomaikaʻi i ka hoʻohana ʻana i ka mana, a mālama kālā. He koho naʻauao no nā noi he nui.
Pehea e hoʻohana ai i ka PoE i kāu Pūnaewele?
ʻO ka wā e hiki mai ana i ka ʻenehana PoE
