Description

The Arista DCS-7816L is a fabric module designed for the Arista 7816 modular chassis, delivering high-speed non-blocking fabric connectivity across all line card slots in large-scale data centre deployments. Supporting graceful degradation for fabric redundancy, this module ensures continuous forwarding even during maintenance or partial failure events — a critical requirement for mission-critical spine and core switching infrastructure.

Designed as a user-serviceable component, the DCS-7816L integrates into the 7800R series ecosystem alongside compatible fabric modules such as the DCS-7808R4-FM and DCS-7804R4-FM. With a typical power draw of 562W and hot-swappable fan modules, it supports high-availability architectures in enterprise and hyperscale data centres.

FAQs

Q: What chassis is the Arista DCS-7816L fabric module compatible with?
A: The DCS-7816L is designed for the Arista 7816 modular chassis, which supports up to 16 line card slots. It is part of the Arista 7800R series modular switching platform used in large-scale data centre spine and core deployments.

Q: Does the DCS-7816L support fabric redundancy?
A: Yes. The DCS-7816L supports graceful degradation, meaning the chassis continues forwarding traffic even if a fabric module experiences a fault — ensuring high availability in mission-critical environments.

Q: Are the fans on the DCS-7816L hot-swappable?
A: Yes. The DCS-7816L includes 8 user-serviceable fan modules that can be replaced without taking the system offline, supporting continuous operation during maintenance.

Q: What is the power consumption of the DCS-7816L?
A: The DCS-7816L draws 562W under typical operating conditions, with a maximum power draw of 936W. Accurate power planning is important when configuring your 7816 chassis power supply configuration.

Q: Can I purchase the Arista DCS-7816L in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking Arista data centre switching components including the DCS-7816L. Orders are dispatched across Australia.

Q: How does the DCS-7816L differ from the DCS-7808R4-FM or DCS-7804R4-FM?
A: The DCS-7808R4-FM and DCS-7804R4-FM are fabric modules for the smaller 7808 and 7804 chassis variants respectively. The DCS-7816L is specific to the larger 7816 chassis and is dimensionally larger with higher power capacity to serve all 16 line card slots.
