Juniper NETWORKS QFX5220-128C Ethernet Shintsha Umhlahlandlela Womsebenzisi

Uhlelo Olungaphezuluview

I-QFX5220-128C o@;rs 128 port of 100-Gigabit Ethernet ku-4 U form factor. Ngomkhawulokudonsa ongu-12.8 Tbps, i-QFX5220-128C iklanywe njengedatha -]]r;]-ঞon noma ngaphezulu kwe-rack kuzikhungo zedatha ezinosayizi ophakathi nendawo kanye nokuthunyelwa kwe-MSDC (Massively Scalable Data Center). Izimbobo ze-Gigabit Ethernet ezingu-100 zingaba yi-conC]†r;7 kungaba ngesivinini esingu-100-Gbps noma esingu-40-Gbps. Izimbobo ze-100-Gbps zingaphinda zihanjiswe ku-2 x 50 Gbps, 4 x 25 Gbps, noma 4 x 10 Gbps. Kunezinhlobo ezimbili ezizinikele ze-factor factor plus (SFP+) zokusekelwa kwe-10-Gigabit Ethernet.
Iphrosesa ye-Intel Xeon D-1500 ishayela indiza yokulawula ye-QFX5220, esebenzisa i-Junos OS Evolved ngakho[wr;ĺ I-Junos OS Evolved so[wr; isithombe sigcinwa kumadrayivu amabili angaphakathi angu-50 GB solid-state (ama-SSD). I-QFX5220-128C iyatholakala nge-port-to-FRUs -brYowķ (-brYow out), kanye nezinsiza zikagesi ze-AC noma ze-DC.

Ingxenye 2: Ground the Chassis bese Uxhuma Amandla

1. Ukuze uxhume umhlaba ku-QFX5220-128C: 1. Sebenzisa izikulufu ezimbili ezingu-10-32 x 0.25 ezinamawasha okukhiya okuhlukanisayo angu-#10 (akunikeziwe) ukuze uvikele isikhwama esiphansi nekhebula elinamathiselwe (akunikeziwe) kuphaneli ye-FRU ye-chassis . Okuthunyelwe kugigi eliphansi kufanele likhombe kwesokudla. Bheka Umfanekiso 5 ekhasini 6.
   Umfanekiso 5: Ukuxhuma i-Grounding Cable ku-QFX5220-128C
   
2. Xhuma isiphetho esisele sekhebuli yaphansi endaweni efanele yomhlaba, njengendawo yokubeka lapho iswishi ifakwe khona.
3. Gqokisa ikhebuli yaphansi futhi uqinisekise ukuthi ayithinti noma ivimbe ukufinyelela kwezinye izingxenye zedivayisi futhi ayijiki lapho abantu bengakhubeka khona.

Xhuma Amandla Ekushintsheni

I-QFX5220-128C ithunyelwa isuka efekthri inezinto ezine zamandla. Ukunikezwa kwamandla ngakunye kuwu-C oshisayo futhi ongafakeki;Ѵ7Ŋr;rѴ-c;-bѴ; iyunithi (i-FRU) lapho ukunikezwa kwamandla kwesibili kufakwa futhi kusebenza. Ungafaka enye indawo kagesi kunoma iyiphi yezikhala ezimbili eduze kwamamojula abalandeli ngaphandle kokunika amandla u-o@ iswishi noma u-7bsr†rঞn] ukushintsha =†ncঞonĺ
Ukuxhuma amandla e-AC ku-QFX5220-128C:

1. Namathisela ibhande eliphansi esihlakaleni sakho esingenalutho kanye nesayithi le-ESD
2. Qinisekisa ukuthi izinsiza zamandla zifakwe ngokugcwele ku-chassis kanye nama-latches
3. Thola izintambo zikagesi ezithunyelwe ngeswishi; izintambo zinamapulaki afanele indawo yakho
   Ngokunikezwa kwamandla ngakunye:
   a. Qinisekisa ukuthi iluphu kusigcini sentambo yamandla ivuliwe futhi kunesikhala esanele sokufaka i-coupler yentambo yamandla endaweni yokungena. Uma iluphu ivaliwe, cindezela ithebhu encane kusigcini ukuze ukhulule iluphu.
   b. Xhuma i-coupler yentambo yamandla ngokusebenzisa iluphu yesibambi sentambo yamandla.
   c. Faka i-coupler yentambo yamandla ngokuqinile embotsheni ye-AC ku-faceplate yokunikezwa kwamandla.
   d. Shelelisela iluphu yesibambi sentambo yamandla iye ngakumandla kagesi ize ibambene nesisekelo se-coupler.
   e. Cindezela ithebhu kuluphu bese udweba iluphu ukuze uvale intambo yamandla.
   Umfanekiso 6: Ukunamathisela Isigcini Sentambo Yamandla
   ISEXWAYISO: Qinisekisa ukuthi intambo yamandla ayivimbi ukufinyelela ezingxenyeni zedivayisi noma i-drape lapho abantu bengakhubeka khona.
4. Uma umthombo wamandla we-AC uneswishi yamandla, yibeke kokuthi VALIWE (O) rosbঞonĺ
   QAPHELA: Iswishi ivula amandla ngokushesha nje lapho amandla enikezwa amandla. Akukho ukushintsha kwamandla kudivayisi.
5. Faka ipulaki yentambo yamandla kumthombo wamandla we-AC.
6. Uma umthombo wamandla we-AC uneswishi yamandla, yibeke kokuthi IVULIWE (|) rosbঞonĺ
7. Qinisekisa ukuthi ama-AC kanye nama-DC LED ekunikezeni kwamandla ngakunye akhanya ngokuluhlaza.
   Uma i-LED yephutha lenhlaka ikhanyisiwe, susa amandla esiphehlisweni samandla, bese ubuyisela indawo kagesi (bona ukuthi Ungawukhipha Kanjani Ukunikezwa kwamandla ku-QFX5220). Ungawususi ugesi †nঞѴ unesisetshenziswa sikagesi esingena esikhundleni esilungile: izinto zikagesi kufanele zifakwe kusiwishi ukuze kuqinisekiswe ukuthi -brYowĺ

ISEXWAYISO: Shintshanisa ugesi ohlulekile unikeze ugesi omusha phakathi nemizuzu emithathu ususiwe ukuze uvimbele i-chassis ov;r_;-ঞn]ĺ

Ngaphambi kokuthi uqale ukuxhuma nokumisa i-QFX5220, setha amanani alandelayo epharamitha kuseva yekhonsoli noma i-PC:

• Isilinganiso se-Baud-9600
• Ukulawula Ukugeleza—Akukho
• Idatha-8
• Ukulingana—Akukho
• Misa amabhithi—1
• Isifunda se-DCD—Ukunganaki
  Xhuma i-QFX5220-128C kunethiwekhi yakho ukuze uthole ukuphathwa ngaphandle kwebhendi:

1. Xhuma ingxenye eyodwa yekhebula ye-Ethernet embobeni yokuphatha (enelebula ethi Mgmt) ku-QFX5220-128C.
2. Xhuma enye ingxenye yekhebula ye-Ethernet kudivayisi yokuphatha.
   Kufanele wenze ukumisa kokuqala kwe-QFX5220 ngembobo yekhonsoli usebenzisa i-CLI noma nge-Zero Touch Provisioning (ZTP). Ukuze usebenzise i-ZTP ukunikeza idivayisi, kufanele ukwazi ukufinyelela iseva ye-Dynamic Host Control Protocol (DHCP), kanye File Iphrothokholi Yokudlulisa (i-FTP engaziwa), I-Hypertext Transfer Protocol (HTTP), noma i-Trivial File Iseva Yokudlulisa Iphrothokholi (TFTP) lapho isithombe sesofthiwe nokucushwa files zigcinwa. Ukuze uthole ukwaziswa okwengeziwe mayelana nokusebenzisa i-ZTP ekuhlinzekeni idivayisi, bheka Ukuqonda i-Zero Touch Provisioning kwe Umhlahlandlela Wokufaka Nokuthuthukisa.

Ukuxhuma kanye ne-conC]†r; ukushintsha kusuka ku-console

1. Xhuma imbobo yekhonsoli kukhompuyutha ephathekayo noma i-PC usebenzisa intambo ye-RJ-45 kanye ne-adaptha ye-RJ-45 kuye ku-DB-9 (hhayi
   enikeziwe). Imbobo yekhonsoli (CON) itholakala ekhoneni eliphezulu kwesokudla sephaneli yembobo.
2. Ngena njengempande. Ayikho iphasiwedi. Uma kunjalo[wr; iqaliswe ngaphambi kokuthi uxhume embobeni yekhonsoli, ungase udinge ukucindezela ukhiye u-Enter ukuze ukwaziswa kuvele.
   Ngena ngemvume: impande
3. Qala i-CLI.

Isifinyezo Sesexwayiso Sokuphepha se-QFX5220-128C

Lesi isifinyezo sezexwayiso zokuphepha. Ukuthola uhlu oluphelele lwezexwayiso, okuhlanganisa ukuhumusha, bheka imibhalo yezingxenyekazi zekhompuyutha ye-QFX5220 kokuthi https://www.juniper.net/documentation/product/en_US/ qfx5220.

ISEXWAYISO: Ukwehluleka ukugcina lezi zexwayiso zokuphepha kungaholela ekulimaleni komuntu siqu noma ekufeni

• Vumela kuphela abasebenzi abaqeqeshiwe nabaqeqeshiwe ukuthi bafake noma bashintshe izingxenye zeswishi
• Yenza kuphela izinqubo ezichazwe kulesi siqalo esisheshayo kanye nemibhalo ye-QFX5220. Amanye amasevisi kufanele enziwe kuphela ngesevisi egunyaziwe
• Ngaphambi kokufaka iswishi, funda imiyalelo yokuhlela emibhalweni ye-QFX5220 ukuze uqiniseke ukuthi isiza sihlangabezana nezidingo zamandla, imvelo, kanye nemvume
• Ngaphambi kokuxhuma iswishi emthonjeni wamandla, funda imiyalelo yokufaka ku-QFX5220
• I-QFX5220-128C inesisindo esingaba ngu-76 lbs (34.5 ) Sincoma ukusebenzisa umshini wokulift ukuze ufakwe ngaphezu kwamayintshi angu-60 (152.4 cm). Ukufaka mathupha i-QFX5220-128C endaweni yokubeka noma ikhabethe endaweni ephakeme ngaphezu kwama-intshi angu-60. (152.4 cm) kudinga abantu ababili ukuthi baphakamise iswishi kanye nomuntu wesithathu ukuze afake izikulufo zokukhweza. Ukuze uvimbele ukulimala, gcina umhlane wakho uqondile futhi uphakamise ngemilenze yakho, hhayi umhlane wakho.
• Uma irack noma iKhabhinethi inemishini yokuzinzisa, yifake endaweni yokubeka ngaphambi kokuyikhweza noma ukusevisa iswishi kurack noma
• Ngaphambi kokufaka noma ngemva kokukhipha ingxenye kagesi, ngaso sonke isikhathi uyibeke phezulu kumata ayisicaba noma ku-antistatic.
• Ungasebenzi emshinini noma uxhume noma unqamule izintambo ngesikhathi kuneziphepho zikagesi
• Ngaphambi kokusebenza emishinini exhunywe ezintanjeni zikagesi, susa ubucwebe, okuhlanganisa izindandatho, imigexo, nezinto ze-Metal shisisa lapho zixhunywe kugesi naphansi futhi kungabangela ukusha okubi kakhulu noma ukushiselwa kumatheminali.

Isexwayiso sekhebula lamandla (isi-Japanese)
ISEXWAYISO: Ikhebuli yamandla enamathiselwe eyalo mkhiqizo kuphela. Ungasebenzisi ikhebula komunye umkhiqizo.

Esimeni sokwehluleka kwehadiwe, sicela uthinte i-Juniper Networks, Inc. ukuze uthole inombolo ye-Return Material Authorization (RMA). Le nombolo isetshenziselwa ukulandelela impahla ebuyisiwe efekthri futhi ibuyisele izingxenye ezikhandiwe noma ezintsha kukhasimende njengoba kudingeka.
