Zero Backplane for Large-scale Smooth Upgrade

The switch can be upgraded during operation by directly replacing line cards and switch fabric modules with higher specifications.
Sole switch in the industry capable of accomplishing 50G/400G large-scale smooth upgrade in the coming 10 years.

The current switch supports 178 Tbps switching capability, 16 slots, and 100G interfaces, and the forwarding
bandwidth of each slot is 3.6 Tbps. The switch can be expended to 346 Tbps switching capacity,
16 slots, and 400G interfaces, and the forwarding bandwidth of each slot is 9.6 Tbps.

Orthogonal Connection Between Service Cards and Switch Fabric Modules, Reducing Signal Transmission Interference by 8%

Fixed in relative to the backplane and non-replaceable,
with switching capacity restricted by backplane or
connector rate, and loss greater than 5%
Direct connection, with large-scale upgrade
via line card and switch fabric module
replacement and interference reduced by 8%

Strongest Chassis Structure Design Requiring Zero Backplane

The backplane of a previous switch provides support. After the backplane is removed, Ruijie uses a keel,
stiffener on chassis sides, and reinforced spacer plate inside the chassis.

To realize a hard chassis structure that can resist a magnitude 9 earthquake.

Accurate Interconnection Between Line
Cards and Switch Fabric Modules with
Zero Backplane

The patented design of 5-level accurate guiding ensures accurate
interconnection between line cards and switch fabric modules.

Line cards are positioned via the limit post and inserted into the chassis via rails.

The positioning pin of the keel corrects the line card direction.

and the line card direction is further corrected using the connector cover and pin,
thereby achieving accurate guiding.

Zero Backplane Technology

Most Space-saving Core Switches in the Industry.

Air vents sharing by fabric modules and line cards,
dramatically saving space.
