Arista 7500 Chassis Core Switches - Refurbished, Used, and New
Arista 7500 series switches are modular chassis for data center spine and core layers, running Arista EOS with redundant supervisors, fabric modules and power supplies. This collection covers the 7500E generation: the four-slot DCS-7504E and eight-slot DCS-7508E chassis, the DCS-7500E-SUP-D supervisor, the Fabric-E modules with integrated fans, and line cards with 10G SFP+, 40G QSFP+, 100G QSFP28, 100G MXP and 100G CFP2 ports. The chassis stays in service while you swap line cards, so a used 7500E is a practical way to add ports or 100G capacity to an existing core. NetworkTigers sells 7500E chassis bundles, supervisors, fabric modules, line cards and power supplies refurbished, used and new. Every unit is tested before it ships so it boots and passes traffic when it arrives.

Which Arista 7500 parts do I need?
Start from the chassis you have or want. The 7504E takes four line cards and the 7508E takes eight, and each takes its own size of fabric module, so a 7508 fabric module does not fit the 7504, while the PWR-2900AC power supply is shared by both. Fabric-E modules are required for E-series line cards; mixing older fabric with E-series cards limits what the cards can do, so tell us which fabric generation is installed. Choose line cards by port type: 48S for 10G, 36Q for 40G, 12CQ for 100G with standard QSFP28 optics, 12CM when you want MXP ports that split into 10G or 40G without changing the card, and 6C2 when you need CFP2 for long-haul optics. Count power supplies against your line card load and the redundancy you want; 100G cards draw more than 10G cards, so a full chassis usually needs more PWR-2900AC units than a lightly loaded one. Run two supervisors if the core cannot tolerate a reboot. Give us your chassis, fabric, supervisor and EOS release and we will confirm a card is supported in that combination before you order.
Frequently asked questions
What is an MXP port?
MXP is Arista's multi-speed MTP/MPO port on the 72S and 12CM line cards. With the right fiber cable one MXP port runs as a single 100G link, three 40G links or twelve 10G links, so you can change port roles with a cable swap rather than a new card.
Can I install 7500R line cards in a 7500E chassis?
The chassis is shared across generations, but R-series line cards need R-series fabric modules and a supervisor and EOS release that support them. A 7500E chassis with Fabric-E modules runs E-series cards; moving to R-series cards means swapping the fabric modules as well.
Does the chassis bundle include line cards?
No. The DCS-7504E-BND covers the chassis and the modules named in its listing. Line cards are sold separately so you can choose the port mix you need, and optics and cables are also separate.
