What are the power specifications?

Two internal redundant field-replaceable load-sharing AC PSUs (1100W each, C14 inlet from back). Max system 350W with one PSU, 332W typical; 100-240 VAC nominal, 12A max per PSU, 6.8A system max. Ensures high availability for datacenter use.

What is the form factor and airflow options?

2U rackmount, 19-inch EIA-compliant chassis. Supports front-to-back or back-to-front airflow with non-port-side exhaust and power intake. Acoustic noise max 87 dBA, nominal 69 dBA; airflow max 370 cmh (218 CFM), min 95 cmh (56 CFM).

What compliance standards are met?

Certifications include ICES-003 Class A, VCCI-Class A, CE, C-Tick, BSMI, KCC Class A, EN55024 immunity, RoHS-6 (lead exemption), NEBS-compliant, and FIPS 140-2 validated. Suitable for regulated enterprise and government datacenters.

Can the QSFP+ ports be used for 10GbE?

Yes, each 40-GbE QSFP+ port breaks out to 4x independent 10-GbE SFP+ ports, enabling up to 48x 10-GbE from the 12 QSFP+ (total 144x 10-GbE with 96 fixed ports). Provides flexible density for server access layers.

What management interfaces are available?

Includes 1x USB Type-A for firmware/diagnostics, 1x 1000Base-T RJ-45 out-of-band Ethernet, 1x RJ-45 RS-232 serial console. Runs Brocade Network OS (now Extreme Networks) for L3 management in datacenter environments.

Product overview

The Brocade VDX 6940-144S (SKU: BR-VDX6940-144S-AC-F) is a fixed-configuration 10/40 GbE Ethernet switch from the ExtremeSwitching VDX 6940 product line, optimized for datacenter spine/leaf topologies. It features 96 fixed 10-GbE SFP+ and TSFP+ optics ports plus 12x 40-GbE QSFP+ ports that breakout to 48x 10-GbE (total 144x 10-GbE capability), with up to 4x 100-GbE dual-personality ports. The 2U rackmount chassis supports front-to-back or back-to-front airflow, with power from the non-port side via two internal redundant field-replaceable 1100W AC PSUs (100-240 VAC, 350W max system). It delivers line-rate throughput across all ports and packet sizes with low latency, suitable for high-density 1/10/40/100 GbE environments. Compliance includes ICES-003 Class A, CE, RoHS-6, NEBS, and FIPS 140-2. Acoustic noise is max 87 dBA, with airflow up to 370 cmh.
