DESCRIPTION
Arista DCS-7508R-FM – 7500R Fabric Module
The DCS-7508R-FM is an Arista 7500R fabric module with an integrated fan module, for the DCS-7508 / DCS-7508N chassis. Six fabric modules are required to populate fabric slots 1-6.
Key Specifications
Chassis support: DCS-7508 / DCS-7508N
Fabric redundancy: 5+1
Integrated fan module: Yes
Typical (max) power: 224 W typical (298 W max)
Weight: 13.4 lbs (6.1 kg)
Dimensions (HxWxD): 2.5 x 14 x 10.25 in (6.4 x 35.6 x 26 cm)
Fully Scheduled Lossless Architecture
The Arista 7500 platform is a purpose-built multi-chip system with end-to-end scheduling: a cell-based fabric sprays uniform cells across all fabric links, Virtual Output Queues eliminate head-of-line blocking, distributed credit scheduling keeps every egress port independent, and deep buffers absorb in-cast and bursts without packet loss – so a fully populated chassis behaves like a single, internally lossless switching chip. All models run Arista EOS.
Deployment Scenarios
Fabric spares: the most common field-replaceable unit in a modular chassis – a failed fabric module degrades capacity until replaced
Capacity restoration: return a partially populated fabric to full bandwidth
Chassis build-out: populate all six fabric slots when commissioning a bare chassis
Frequently Asked Questions
How many DCS-7508R-FM modules does a chassis need?
Six fabric modules populate fabric slots 1-6 on the DCS-7508 / DCS-7508N. Running fewer reduces available fabric bandwidth.
Does the DCS-7508R-FM include a fan?
Yes. The fabric module has an integrated fan module – fabric and cooling are a single field-replaceable unit.
Which chassis is the DCS-7508R-FM compatible with?
The DCS-7508R-FM is designed for the DCS-7508 / DCS-7508N chassis. Fabric modules are generation-specific and are not interchangeable across 7500 generations.
Is the refurbished DCS-7508R-FM tested before shipping?
Yes. BrightStar Systems inspects and tests every unit on original-spec firmware, performs a factory reset and configuration wipe, and backs it with warranty (1 year end-user / 90 days reseller).
BrightStar Systems supplies professionally tested refurbished Arista 7500 Series hardware.
