Ibisobanuro
| Ibikoresho byihariye byo kubaka telefoni zo mu rugi rwa videwo (bishyigikira ibirango byose bya IP byo kubaka telefoni zo mu rugi rwa videwo) |
| 24V (uburyo bwo gutanga amashanyarazi: 45+, 78-) |
| switch yo gukanda kugira ngo uhitemo transmission 100m cyangwa 250m |
| inzu ifite aho ifungira umwobo ku rukuta, kandi byoroshye kuyishyiraho. |
| Inama ishyushye: witondere uburyo imiyoboro y'amashanyarazi ikurikirana - uburyo bworoshye; (cyangwa umuyoboro wa gigabit 1 uturutse hejuru, imashini ikoresha uburyo busanzwe bwo gukaraba) |
| hamwe n'imikorere yo kurinda umuriro w'amashanyarazi |

Ibibazo Bikunze Kubazwa
Ikibazo cya 1. Ni iyihe ntego ya sisitemu y'inyubako ya videwo ya IP ikoreshwa mu kubaka amarembo?
A: Sisitemu ya IP y’inyubako ifite videwo ya intercom y’umuryango yagenewe gutanga itumanaho ryizewe kandi ryoroshye no kugenzura uburyo inyubako zifite amazu menshi zinjiramo. Yemerera abaturage kuvugana n’abashyitsi bari ku muryango, kubareba binyuze muri videwo, no kubaha uburenganzira bwo kwinjira iyo bibaye ngombwa.
Q2. Ni iki gikoresho cya POE kidasanzwe n'uruhare rwacyo muri sisitemu?
A: Imashini idafite POE isanzwe ni imashini ikoresha amashanyarazi kuri Ethernet yagenewe by’umwihariko sisitemu ya IP building videwo intercom. Itanga amakuru n’ingufu ku bagenzuzi b’imbere mu nzu n’ibindi bikoresho bihujwe, byoroshya uburyo bwo kuyishyiramo, isaba gusa umurongo umwe wa CAT6/CAT6 kuri buri gikoresho.
Q3. Ni iki gisobanuro cy'imiterere itandukanye ya port (4 + 2, 8 + 2, 16 + 2, 24 + 2) muri switch za POE zidasanzwe?
A: Imiterere itandukanye y’aho hantu ihurira n’umubare w’aho hantu ho gukorera (monitors) mu nzu hashobora guhuzwa n’aho hantu ho gukorera (switch). Urugero, aho hantu ho gukorera (switch) hashobora gukoresha (controls) kugeza kuri 8 mu nzu, hamwe no gutanga amahitamo yo guhuza imiyoboro binyuze muri izo ports ebyiri z’inyongera.
Q4. Intego ya "Dip switch" muri izi switch ni iyihe?
A: "Dip switch" igamije guhitamo intera yo kohereza ibikoresho bihujwe. Ishobora guhindurwa kugira ngo ihitemo hagati y’intera yo kohereza ya metero 100 cyangwa metero 250, bitewe n’ibisabwa byihariye byo gushyiraho.
Q5. Ese ushobora gusobanura amashanyarazi yubatswemo n'akamaro kayo?
A: Ingufu zubatswemo zitanga ingufu z'amashanyarazi zikenewe haba kuri switch ubwayo ndetse no kuri moniteur zo mu nzu zihujwe. Bikuraho gukenera andi masoko y'amashanyarazi kandi bigatuma inzira yo kuyishyiraho irushaho kuba nziza, byoroshya uburyo bwo kuyishyiraho no kuyibungabunga.
Ikibazo cya 6. Ni gute sisitemu ishyigikira imikoranire muri iyi mashini?
A: Izi mashini zirimo imiyoboro y'itumanaho ihuza itumanaho (uplink network ports) yoroshya itumanaho muri iyo mashini. Izi mashini zituma habaho itumanaho ritagorana hagati y'ibikoresho bitandukanye biri mu nyubako imwe, bigafasha mu gutumanaho kwumvikana neza kandi ku buryo bunoze.
Q7. Ni izihe ngano n'uburemere by'izi swichi za POE zidasanzwe?
A: Ingano n'uburemere biratandukanye bitewe n'imiterere y'aho umuyoboro uherereye. Ingano iri hagati ya 202 * 140 * 45 mm na 310 * 182 * 45 mm, naho uburemere buri hagati ya 1.1 kg na 2.2 kg, bigatuma igishushanyo mbonera gito kandi gikoresha neza umwanya ujyanye n'ibikenewe bitandukanye byo gushyiraho.
Ikibazo cya 8. Ese switch ya POE idasanzwe ishobora guhindurwa ku buryo butandukanye bwo kuyishyiraho?
A: Yego, amwe mu mamodeli atanga uburyo bwo gushyiraho ibikoresho bitandukanye nko gushyirwa kuri mudasobwa cyangwa gushyiraho amatwi yo gushyiramo ibikoresho mu kabati. Ubu buryo bworoshye butuma habaho uburyo butandukanye bwo gushyiraho ibikoresho kandi bugatuma bihura n’ibidukikije bitandukanye.
Q9. Ese ushobora gusobanura igihe cy'ingwate kuri izi swichi?
A: Imashini zose zidasanzwe zo guhinduranya amashanyarazi (Non-standard POE switches) ziza zifite garanti y'umwaka umwe. Iyi garanti ikubiyemo inenge zo mu nganda kandi ikerekana ko izi mashini zikora neza mu gihe cyose zigenewe.
Ikibazo cya 10. Intego y'aho amashanyarazi ya Gigabit cascade na port ya SFP muri models nini zo guhindura ni iyihe?
