Frequently Asked Questions

Question:

What’s the difference between the DS4000 and DS4001?
[email protected]
13-Jul-2025

Answer:

They are very similar. The primary differences are the Celestica DS4001 supports higher sub-rate flexibility, including 168 x 50GbE and 64 x 200GbE ports, compared to the DS4000, which tops out at 144 x 10/25/50GbE or 128 x 100GbE. The DS4001 also features a larger 70MB buffer (vs. 64MB), newer BMC hardware (DDR4 and dual 32MB flash).

Question:

Can this switch support both airflow directions?

13-Jul-2025

Answer:

Yes.

Question:

Can I break out the 400G ports into lower speeds like 25G or 100G?
[email protected]
13-Jul-2025

Answer:

Yes. Each QSFP-DD port can be broken out, enabling support for up to 144× 10/25/50G or 128× 40/100G sub-ports.

Question:

What types of optics are supported?
[email protected]
12-Oct-2026

Answer:

The DS4000 supports QSFP-DD transceivers up to 12W with back-to-front airflow or 20W with front-to-back airflow. DAC cables are supported up to 3m. Use optics and cables qualified for the selected hardware and NOS.

Question:

Can I run commercial NOS like NVIDIA Cumulus or IP Infusion on this switch?
[email protected]
12-Oct-2026

Answer:

Confirmed SONiC options for the DS4000 include Community SONiC, Celestica SONiC and Enterprise SONiC Distribution by Broadcom. Cumulus Linux or OcNOS requires a DS4000-specific qualification for the intended release; ONIE compatibility alone does not establish that support. Other NOS options may be available as the ecosystem evolves.

Question:

Is this switch suitable for spine, leaf, or both?
[email protected]
13-Jul-2025

Answer:

Both.
