Description

The Arista 7500R Series fabric module is a rear-inserted module with an integrated fan assembly, built for the Arista 7512 modular chassis (7512N). It interconnects every line card in a non-blocking, active-active fabric, making it a core building block for large-scale data centre, cloud and VXLAN overlay spine designs.

The module draws a typical 570 W, with a maximum of 680 W, and is powered from the chassis midplane, so it has no separate power supply. It measures 2.5 x 21 x 10.25 in (6.4 x 53 x 26 cm), weighs 25 lbs (11.4 kg) and supports 5+1 (N+1) redundancy. A 7512N chassis delivers up to 115 Tbps and 51 Bpps of system throughput.

This fabric module is specific to the 7512 / 7512N chassis (DCS-7512N-CH) and is installed in fabric slots 1 to 6, with six modules required. The 7512 chassis supports 7500R Series line cards only. The module is not interchangeable with the 7516R-FM, 7508R-FM or 7504R-FM.

FAQs

Q: Does this fabric module need a licence?
A: No licence is required for the fabric module itself. Software features on the 7500R chassis are licensed separately through the LIC-MOD-x software licences.

Q: How is the fabric module powered?
A: It is powered from the chassis midplane and has no separate PSU. Typical draw is 570 W, with a maximum of 680 W. The 7500R chassis uses N+N 3000 W AC or DC power supplies.

Q: Which chassis and line cards does it work with?
A: It is specific to the 7512 / 7512N chassis (DCS-7512N-CH), which supports 7500R Series line cards such as the 7500R-36CQ-LC and 7500R-36Q-LC, along with 7500R2 and 7500R2A variants.

Q: How many fabric modules does the 7512 chassis need?
A: Six modules are required, one for each of fabric slots 1 to 6, giving 5+1 redundancy.

Q: Can it be used in other 7500R chassis or with 7500R3 systems?
A: No. It is not interchangeable with the 7516R-FM, 7508R-FM or 7504R-FM. 7500R3 systems use the DCS-7512R3-FM instead.
