Description

The Arista DCS-7800-SUP1A is the Supervisor1A control-plane module for the Arista 7800R3 Series modular data centre switch routers. It runs Arista EOS and handles control plane and management functions for the 7808 and 7804 chassis. It suits modular spine, data centre core, internet peering and data centre interconnect deployments, with a single supervisor or a dual 1+1 redundant pair.

The module uses a six-core 1.9 GHz x86 64-bit processor with 64 GB of system memory, 4 GB of flash and a 240 GB SSD. Management and console access is provided by one RJ-45 port, one 1G SFP port, two USB 2.0 ports and one RS-232 serial port. Typical power draw is 61 W, with a maximum of 72 W, supplied through the chassis. This is the Supervisor1A variant and is not the secure-boot model.

This supervisor is for the DCS-7808 and DCS-7804 chassis only. The 7816L, 7816 and 7812 chassis use DCS-7816-SUP or DCS-7816-SUP1S. The secure-boot variant for the 7808 and 7804 is DCS-7800-SUP1S.

FAQs

Q: Which chassis does the DCS-7800-SUP1A fit?
A: It is for the Arista 7800R3 DCS-7808 and DCS-7804 chassis only. The 7816L, 7816 and 7812 chassis use DCS-7816-SUP or DCS-7816-SUP1S.

Q: Does this supervisor need a separate licence?
A: No separate licence is stated for the supervisor itself, as it runs Arista EOS. Some EOS features, such as encryption services, require a licence file.

Q: Can I run two supervisors for redundancy?
A: Yes. One supervisor is needed to run the system, and a second can be added for 1+1 redundancy with stateful switchover.

Q: Is this the secure-boot supervisor?
A: No. The SUP1A is not the secure-boot model. The secure-boot variant for the 7808 and 7804 chassis is DCS-7800-SUP1S.

Q: How much power does the supervisor draw?
A: Typical draw is 61 W and the maximum is 72 W. Power is supplied by the chassis through its grid-redundant power supplies.
