EX 8200 Series
Řada L3 přepínačů EX 8200 firmy Juniper Networks nabízí pružnou modulární platformu přinášející vysokou hustotu portů, škálovatelnost a vysokou dostupnost požadovanou pro současná datová centra a páteře podnikových sítí.
 |
EX8208 obsahuje přepínací matici nabízející obousměrnou propustnost 320 Gb/s (full duplex) na jeden slot, což umožňuje plnou rychlost všech portů při všech velikostech paketů. Pasívní sběrnice podporuje rychlost až 6.2 Tb/s, což přináší možnost rozšíření do budoucna Hlavní vlastnosti EX8208 vycházejí z Juniper EX-PFE2 ASICs a z využití operačního systému Junos a nabízí schopnosti potřebné pro vysoce výkonné sítě jak dnes tak v budoucnu. |
Přepínač EX8208 nabízí 8 pozic pro karty s různými typy Ethernet rozhraní - 48 portů 10/100/1000BASE-T RJ-45 UTP, 48 portů 100BASE-FX/1000BASE-X SFP a 8 portů 10GBASE-X SFP+. Plná kapacita tohoto šasi je až 384 GE nebo 64 10GE portů
| EX8200-48F | 48-port 100FX/1000BASE-X SFP line card; requires SFP optics sold separately |
| EX8200-48T | 48-port 10/100/1000BASE-T RJ-45 line card |
| EX8200-8XS | 8-port 10GbE SFP+ line card; requires SFP+ optics sold separately |
Klíčové výhody:
- Vysoká dostupnost (redundantní zdroje, management, přepínací matice)
- Operační systém Junos prověřený nasazením u operátorů
- Zjednodušený management a údržba (podpora Junos CLI, WEB management, Network and Security Manager - NSM)
