Hōʻea hou ʻo Kina Gigabit Ethernet Optical Fiber Switch - 48 + 4 10G Management Fiber Ethernet Switch JHA-SW4804MG-52VS – JHA

48 + 4 10G Management Fiber Ethernet Hoʻololi

JHA-SW4804MG-52VS

Phuahana ʻike nui 

ʻO JHA-SW4804MG-52VS kahi hoʻololi maʻamau BCM chip series.

Hāʻawi ka hoʻolālā modular i 48 10/100/1000 adaptive ports a me 4 integrated terabyte optical ports, e hāʻawi ana i ka bandwidth lawa no ka hoʻololi ʻikepili ma waena o ka hui a me ke kumu.

Hāʻawi i ka mana hoʻololi kiʻekiʻe, ke kulekele hoʻomalu palekana kūpono a me ke kulekele pale CPU e hoʻomaikaʻi i ka hoʻomanawanui hewa, a e hōʻoia i ka hana paʻa o ka pūnaewele a me ke kaulike o ka loulou.

I kēia manawa, kākoʻo ia i ka pale ʻana i ka hoʻouka kaua DoS a me SNMP, IEEE 802.1, spanning tree, fast spanning tree protocol, link aggregation a me nā hana ʻē aʻe.

 Phuahana hiʻona 

1、 He mea kupaianaha ka hana

2, 176G backplane bandwidth

3、 Ø ka hoʻokele ʻana i nā lako lako, ʻo ka pae uea-wikiwiki 3 hoʻololi ʻana i ka pākēkē i hiki i 131 MPPS

4、 Ø hiki ke hoʻonoho ʻia i loko o ka ʻoihana metropolitan area, a hāʻawi i kahi ʻenehana 1 km hope loa.

5、 Ø/IEEE802.3 ka nui o ka pahu Ethernet (64 bytes a 1522 bytes)

6、 Ø mau ʻeke nunui a hiki i 9216 bytes

1. Hāʻawi i ka pale kūʻē iā DOS, ka hoʻolele ʻana i ka lawelawe, spoofing, a me nā virus

Ø kākoʻo iā IEEE802.1 x, hāʻawi i ka hōʻoia mea hoʻohana e pili ana i ke awa, ka ʻenehana pale mesh, ka ʻenehana hoʻomalu palekana a me ka papa inoa hoʻolālā.

Ø palena i ka helu o ka pilina pili loa ma waena o kahi mea hoʻokipa a me ka interface Ethernet no ka hoʻopaʻa ʻana he nui, hoʻonui i ka bandwidth a me ka redundancy system

Ø ACL ikaika, kākoʻo i ka kānana ʻikepili papa L2 - L4

Ka papa inoa hoʻomalu kulekele, hoʻoponopono kahe

8.Easy e hoʻohana a mālama

Hiki ke mālama ʻia e ka Pūnaewele, SNMP a pēlā aku

Ø kākoʻo i ka protocol XModem, hiki ke hoʻonui i ka polokalamu TFTP/ZMODEM a me ka BootRom

Ø kākoʻo iā SFP +, a me ka hoʻohālikelike hope XFP, etc

9.Strong traffic and broadcast management

ʻO ka ʻike maʻalahi a me ka hoʻopau ʻana i ka ʻino hoʻolaha, kākoʻo i ka ʻike ʻana i ka memo IGMP, hoʻopaʻa pono i ka kahe ʻana o ka leka uila.

Kākoʻo ʻo Ø i ke ʻano full-duplex a me ka hapalua duplex mode o ka mana kahe

Ø kākoʻo i ka pilina Ethernet ma 1 m e like me ka helu palena ʻana i ka lōʻihi

Nā palena ʻenehana huahana

i loko ʻO ka hōʻoia o ka maikaʻi o ka huahana a me ka hōʻoia

♦ Ka lawe ʻana a me ka mālama ʻana i nā huahana

♦ U lawe: ua kūpono ka hōʻailona o kēia huahana no ka lawe ʻana i nā kaʻa, nā moku, nā mokulele a me nā kaʻaahi. I ka wā o ka lawe ʻana, pono e pale ʻia mai ka lā, drenching a me ka hoʻouka ʻana a me ka wehe ʻana.

♦ Waihona: pono e hoʻokomo i ka huahana i loko o ka pahu pahu ke hoʻohana ʻole ʻia. Pono ka mahana a me ka haʻahaʻa o ke kaiapuni mālama i nā koi o ka huahana. ʻAʻole pono nā mea corrosive i loko o ka hale kūʻai a ʻaʻohe ikaika mechanical vibration, hopena a me ka hana magnetic field.
