ʻO ka mana ma luna o kaʻenehana Ethernet (PoE) hiki i nā'eneke laina Ethernet pono ke hana e like me nā kaula mana. Ma kahi o ka PoE-enabled network, ke holo pololei ke alaula (DC) ma luna o ke kaula pūnaewele me kaʻikeʻikeʻike Ethernet pono. ʻO ka hapanui o nā poE e pili ana i ka standard IEEE 802.3af aiʻole 802.3at .
Ua hoʻolālāʻia ka mana ma luna o ka Ethernet no ka hoʻohanaʻana i nā mea ponoʻeleʻele a me ka leka uila e like me nā wahiʻike Wi-Fi (AP) , nā pūnaewele pūnaewele, a me nā hua'ōlelo VoIP . Poe e hoʻolako i nā meahana pūnaewele i nā pāpale aiʻole nā paia o ke āpau kahi i hikiʻole ai i nā kālai uila ke komo.
ʻO keʻenehana i piliʻole i ka PoE,ʻo Ethernet ma luna o nā laina mana e hiki ai i nā līlī laina hili maʻamau ke hana e like me nā laikini Ethernet lōʻihi.
No ke aha nui Home Networks Don & # 39; • E hoʻohana i ka Mana Ma o Ethernet
Ma muli o ka nui o nā hale e loaʻa ana i nā papa hana mana a me nā'īlio liʻiliʻi o Ethernet, a he nui nā kāwiliʻoihana e hoʻohana i nā mea Wi-Fi ma kahi o Ethernet,ʻo ka hoʻohanaʻana o ka PoE no ka haipina home. Hiki i nā mea kūʻai pūnaewele ke komo wale i ka hoʻokūkū PoE ma kā lākou mau papahana kiʻekiʻe a me nā papahanaʻoihanaʻoihana a me nā hoʻololi kelepona no kēia kumu.
Hiki i nā mea hoʻohana kālā ke hoʻonui i ka PoE i ka hoʻohanaʻana i ka Ethernet ma ka hoʻohanaʻana i kahi mea liʻiliʻi a me ka'ōnaehana i kapaʻiaʻo PoE injector. ʻO kēia mau polokalamu e pili ana i nā kikowaena Ethernet (a me ka mea hoʻololi mana) e hiki ai i nā kaula Ethernet maʻamau me ka mana.
He aha nāʻano o nā mea hana e hana me ka mana ma o Ethernet?
ʻO ka nui o ka mana (i watts) e hiki ke hoʻolakoʻia ma luna o Ethernet ke kaupalenaʻia e kaʻenehana. ʻO ka paepae kūpono o ka mana e pono ai ma muli o ka nānāʻiaʻana o ka PoE a me ka unuhi hukihana o nā mea hoʻohana. IEEE 802.3a, i kekahi laʻana, e hōʻoiaʻiʻo i ka 12.95W wale nō o ka mana ma kahi pili i hāʻawiʻia. ʻAʻole hiki i nā PC a me nā kamepiula ke hana ma luna o ka PoE no ko lākou mau mana ikaika kiʻekiʻe (ʻo 15W a me ka piʻi), akā nā polokalamu kelepona e like me nā kamepiula i hana ma lalo o 10W. Hiki i kekahi pūnaewele pāʻoihana ke hoʻokomo i kahi loiloi PoE a hiki i kahi hui pūnaewele a iʻole nā mea likeʻole.
