Arista 7500R & 7800R Modular Spine Maintenance — vendor-independent service
We service Arista Modular Spine chassis after factory warranty and Arista A-Care — vendor-independent, with OEM line cards, supervisor modules, power supplies and fan trays, SLA up to 24×7×4. Complete family: 7500R series (7504R to 7516R) and 7800R series (7804R3 to 7816R3, current with 400G). 30 to 60 percent below Arista A-Care, up to 70 percent on EOSL 7500R first generation.
Which modular spine models we service
Modular spine platforms are the most demanding Arista devices from a maintenance perspective — complex chassis with redundant supervisor modules, multiple line cards, switch fabric modules and N+1 or N+N power redundancy. Two generation families coexist in DACH data centers: 7500R (released 2014, several sub-generations R/R2/R3) and 7800R (released 2020+, current generation with 400G).
Why TPM maintenance for 7500R & 7800R
Modular spine maintenance is the highest lever in the Arista maintenance portfolio. Arista A-Care for a fully populated 7516R with 16 line cards, redundant supervisor modules and N+N power supply redundancy moves into five to six-figure amounts per year. For 7800R platforms (higher backplane bandwidth, 400G connectivity), the hardware value is even higher — and Arista A-Care correspondingly more expensive. TPM reduces these maintenance terms to 35-50 percent without limiting EOS, MLAG, EVPN or other software functionality.
We service 7500R and 7800R with OEM line cards, supervisor modules, switch fabric modules, power supplies and fan trays from our own warehouse. 7500R has gone through three line card generations over the years (R, R2, R3) — components are not interchangeable across generations, so we stock all generations. 7800R uses its own line card generation R3 with 400G optimization. For very old 7500R first-generation components, we use certified refurbishing partners from the service provider networking ecosystem.

EOSL status of modular spine generations
Modular spine generations follow an 8-12 year lifecycle. Early 7500R first generation has reached EOSL, 7500R2/R3 are approaching, 7800R3 is current.
