DESCRIPTION
Arista DCS-7804R3-FM – 7800R3 Fabric Module
The DCS-7804R3-FM is the fabric module for the Arista DCS-7804 chassis; 6 required (fabric slots 1-6) per system. The 7800R3 cell-based fabric sprays uniform cells across all fabric links for 100% efficiency, and fabric redundancy follows a graceful-degradation model – the system continues forwarding at reduced fabric capacity if a module is removed or fails.
Integrated cooling: 4 user-serviceable fan modules
Typical (max) power: 180 W typical (248 W max)
Dimensions (HxWxD): 2.5 x 11.8 x 22.7 in (6.4 x 30 x 57.6 cm)
Weight: 20 lbs (9.1 kg)
Installation: rear of chassis (direct line-card connection, midplane-less design)
Frequently Asked Questions
Which chassis uses the DCS-7804R3-FM?
The DCS-7804R3-FM is specific to one chassis size – see the specifications above for the supported chassis and required quantity. Fabric modules are not interchangeable across chassis sizes.
What happens if a fabric module fails?
The 7800 fabric supports graceful degradation: the system keeps forwarding at reduced fabric capacity while the module is replaced from the rear of the chassis.
Are the fans field-replaceable?
Yes – each module carries user-serviceable fan modules, replaceable without removing the fabric module.
