Kuyini ukushintshwa kwe-POE?
Ezweni lanamuhla elisheshayo, ubuchwepheshe buthuthuka ngesivinini esisheshayo.Njengoba isidingo sabantu sokuxhumeka kwenethiwekhi okusebenzayo nokulula sikhula, okokusebenza okufana nokushintsha kwe-POE sekubalulekile.Ngakho-ke iyini ngempela ukushintsha kwe-POE futhi inaziphi izinzuzo ngathi?A P...Funda kabanzi -
Indlela yokuhlukanisa i-POE engajwayelekile ku-POE evamile?
1. I-PoE engajwayelekile kanye ne-PoE evamile Ye-PoE evamile ethobela amazinga e-IEEE 802.3af/at/bt futhi enephrothokholi yokuxhawula.I-PoE engajwayelekile ayinayo iphrothokholi yokuxhawula, futhi inikeza ugesi ongu-12V, 24V noma ongu-48V DC ogxilile.I-switch ejwayelekile ye-PoE ine-PoE control c...Funda kabanzi -
Yini okufanele inakwe lapho ukhetha imojula ye-optical ehambisanayo?
Imojula ye-optical iyisisekeli esiyinhloko sesistimu yokuxhumana ye-optical futhi idlala indima ebalulekile ekuxhumaneni kwe-optical fiber.Ngokuyinhloko iqedela umsebenzi wokuguqula isithombe sikagesi.Ikhwalithi yemojuli ye-optical inquma ikhwalithi yokudlulisela yenethiwekhi ye-optical.Ukukhetha okuphansi...Funda kabanzi -
Uyini umehluko phakathi kweswishi ye-POE kanye neswishi evamile?
1. Ukuthembeka okuhlukile: Amaswishi e-POE amaswishi asekela ukunikezwa kwamandla kuzintambo zenethiwekhi.Uma kuqhathaniswa nokushintsha okujwayelekile, amatheminali athola amandla (njengama-AP, amakhamera edijithali, njll.) awadingi ukwenza izintambo zamandla, futhi athembeke kakhulu kuyo yonke inethiwekhi.2. Umsebenzi ohlukile...Funda kabanzi -
Lapho uthenga iswishi, liyini izinga le-IP elifanele leswishi yemboni?
Izinga lokuvikela lokushintsha kwezimboni libhalwe yi-IEC (International Electrotechnical Association).Imelwe i-IP, futhi i-IP ibhekisela “kukuvikela ukungena.Ngakho-ke, lapho sithenga ukushintshwa kwezimboni, iliphi izinga le-IP elifanele lokushintshwa kwezimboni?Hlela uhlelo lukagesi...Funda kabanzi -
Thuthukisa — Iswishi ye-Ethernet yezimboni engu-8 ephethwe enezimbobo zefayibha ezimbili
Ukuze kuhlangatshezwane nezidingo zamakhasimende ethu, sithuthukise i-8-port ephethwe yi-industrial switch, futhi usayizi womkhiqizo uye waba mncane, onganciphisa izindleko zokuhamba futhi wonge isikhala;Okulandelayo izici ezibalulekile zomkhiqizo: *Sekela i-2 1000Base-FX fiber port kanye ne-8 10...Funda kabanzi -
Yiziphi izindlela zokuphatha amaswishi?
Kunezinhlobo ezimbili zezindlela zokuphatha ukushintsha: 1. Ukuphathwa kweswishi ngembobo ye-console yeswishi kungokwabaphathi abangaphandle kwebhendi, okubonakala ngokuthi asikho isidingo sokuthatha isixhumi esibonakalayo senethiwekhi, kodwa ikhebula okukhethekile futhi nebanga lokumisa lifushane...Funda kabanzi -
Ungakhetha kanjani inkinobho efanele?
Njengamanje, kunezinhlobo eziningi zokushintshwa emakethe, futhi ikhwalithi ayilingani, ngakho yiziphi izinkomba okufanele sizinake lapho sithenga?1. Umkhawulokudonsa ongemuva;Isendlalelo se-2/3 sokushintsha kokuphuma;2. Uhlobo lwe-VLAN nenani;3. Inombolo nohlobo lwamachweba okushintsha;4. Izivumelwano zokusekela kanye nami...Funda kabanzi -
Uyini umehluko phakathi kweswishi ye-Layer 2 kanye ne-Layer 3 switch?
Umehluko obalulekile phakathi kweswishi ye-layer-2 kanye ne-layer-3 switch ukuthi isendlalelo sephrothokholi esisebenzayo sihlukile.Iswishi ye-layer-2 isebenza kusendlalelo sesixhumanisi sedatha, futhi iswishi ye-layer-3 isebenza kungqimba yenethiwekhi.Kungaqondwa kalula njengendawo yokushintsha ungqimba 2.Ungacabanga ukuthi inakho kuphela ...Funda kabanzi -
Uyini umehluko phakathi kwamamojula wembobo kagesi namamojula optical?
I-module ye-copper port iyimojula eguqula i-optical port ibe yi-port kagesi.Umsebenzi wayo ukuguqula amasignali optical abe amasignali kagesi, futhi uhlobo lwesixhumi esibonakalayo yi-RJ45.Imojula ye-optical-to-electrical iyimojula esekela ukushintshashintsha okushisayo, futhi izinhlobo zephakheji zifaka i-SFP,...Funda kabanzi -
Ingabe Ukushintsha Kwe-Industrial Ethernet Kusuka Kubakhiqizi Abahlukene Kungayakha Inethiwekhi Yendandatho Engafuneki?
Njengomkhiqizo obalulekile wokuxhumana kwedatha, ukushintshwa kwe-Ethernet yezimboni kufanele kuvuleke futhi kuhambisane nemikhiqizo evela kubakhiqizi abaningi ukuze kuqinisekiswe ukusebenza okuzinzile nokuphephile kwesikhathi eside kohlelo.Uma uthembele kuphela kumkhiqizi othile, ubungozi buphezulu kakhulu.Ngakho-ke, ngokusekelwe ku-s...Funda kabanzi -
Indlela Yokukhetha Ukushintsha Kokuvikela?
Amaswishi okuphepha, abuye aziwa ngokuthi ama-PoE switch, aklanyelwe izindawo zenethiwekhi ezilula njengamakhaya, izindawo zokulala zezikole, amahhovisi, nokuqapha okuncane.Okokuqala, akulungile ukusebenzisa umthamo weswishi ukubala inani lamakhamera anamakhamera.Kusadingeka ukuthi kubhekiselwe ku...Funda kabanzi
