Te rerekētanga i waenga i ngā pana PoE me ngā pana noa

I roto i te ao hangarau whatunga e whanake tonu ana, he mea nui te whiriwhiri i te pana hei whakapai ake i te whai huatanga me te mahi a te whatunga. I roto i ngā momo pana maha, kua aro nuihia ngā pana Mana i runga i te Ethernet (PoE) nā ō rātou āhuatanga ahurei. He mea nui te mārama ki ngā rerekētanga i waenga i ngā pana PoE me ngā pana paerewa mō ngā pakihi me ngā tāngata takitahi e hiahia ana ki te whakapai ake i te hanganga whatunga.

A Pana PoE He taputapu whatunga tēnei e tautoko ana i te tuku raraunga, engari e whakarato ana hoki i te hiko ki ngā taputapu hono mā te taura Ethernet kotahi. Mā tēnei hangarau ka taea e ngā taputapu pēnei i ngā kāmera IP, ngā waea VoIP, me ngā pūwāhi urunga ahokore te whiwhi raraunga me te hiko i te wā kotahi, ā, kāore e hiahiatia he pūtake hiko motuhake. Kei te wātea ngā pana PoE i roto i ētahi paerewa, tae atu ki te IEEE 802.3af (PoE), IEEE 802.3at (PoE+), me te IEEE 802.3bt (PoE++), ia mea e tuku ana i ngā taumata hiko rerekē hei whakauru i ngā momo taputapu.

Ko ngā pana paerewa, i tētahi atu ringa, he taputapu whatunga tuku iho e whakamahia ana mō te tuku raraunga. Kāore e tukuna he hiko ki ngā taputapu hono, ko te tikanga me mono tetahi taputapu e hiahia ana ki te hiko ki tētahi putanga hiko motuhake. Ko ngā pana paerewa e whakamahia ana i ngā taiao kua whakakahangia ngā taputapu, kāore rānei he āwangawanga mō te hiko.

Mana:Ko te rerekētanga nui i waenga i te pana PoE me te pana noa ko tōna kaha tuku hiko. Ka taea e te pana PoE te whakakaha i ngā taputapu mā te taura Ethernet, engari kāore e taea e te pana noa. Mā tēnei āhuatanga ka māmā ake te tāutanga, ka whakaitihia hoki te raruraru o ngā taura me ngā urutau hiko.

Ngāwari o te tāutanga:He nui ake te ngāwari o te whakanoho i ngā taputapu e ngā pana PoE. Nā te mea kāore e hiahiatia he putanga hiko tata, ka taea te tāuta i ngā taputapu ki ngā wāhi kāore e wātea ana te hiko, pērā i ngā kāmera IP kei runga i te tuanui, i ngā wāhi tawhiti rānei mō ngā pūwāhi urunga ahokore. Heoi, ko ngā pana tuku iho me whakanoho ngā taputapu ki ngā wāhi e wātea ana te hiko.

Te whai hua o te utu:Ahakoa he nui ake te utu tīmatanga o ngā pana PoE i ngā pana noa, ka taea e rātou te penapena moni i te wā roa. Mā te whakaiti i te hiahia mō ngā waea me ngā putanga tāpiri, ka taea e ngā pakihi te penapena i ngā utu tāutanga me te tiaki. Hei tāpiri, mā te kaha ki te whakakaha i ngā taputapu maha mā te pana kotahi ka whakaiti i te whakapaunga hiko.

Whakahaere whatunga:He maha ngā pana PoE e wātea ana me ngā āhuatanga whakahaere matatau e āhei ai te whakahaere me te aroturuki pai ake i ngā taputapu hono. Kei roto i tēnei ko te whakarite i te mana matua, te aroturuki i te whakapaunga mana, tae atu ki te whakaara anō i ngā taputapu mai i tawhiti. He maha ngā wā kāore ēnei āhuatanga whakahaere matatau i roto i ngā pana paerewa.

Te Tauine:Ko ngā pana PoE he whānui ake te whānui i ngā pana paerewa. I te tipu haere o tō pakihi, me te hiahia hoki ki ētahi atu taputapu, ka taea e ngā pana PoE te whakauru ngāwari i ngā taputapu hou me te kore e hiahiatia he mahi hiko nui. I tētahi atu taha, ko ngā pana paerewa, me whai hanganga tāpiri hei tautoko i ngā taputapu hiko hou.

Hei whakamutunga, ko te whiriwhiri i waenga i te Pana PoE ā, ko te pana paerewa e whakawhirinaki ana ki ngā hiahia motuhake o tō whatunga. Mō ngā taiao e hiahia ana ki ngā taputapu hiko, he nui ngā painga o ngā pana PoE ki te tuku hiko, te ngāwari o te tāutanga, te whai huatanga o te utu, te whakahaere whatunga, me te tauine. Mā te mārama ki ēnei rerekētanga ka āwhina i ngā pakihi me ngā tāngata takitahi ki te whakatau whai whakaaro i te wā e hoahoa ana, e whakapai ake ana hoki i ā rātou hanganga whatunga. I te haere tonu o te whanaketanga o te hangarau, tera pea ka nui ake te hiranga o te tūranga o ngā pana PoE i roto i ngā whatunga hou, ka waiho hei taonga nui mō tētahi whakahaere.
