What is the difference between the QW937A and QW937B models?

Both are SN3000B 16Gb 24-port/12-port switches with identical specifications. QW937A ships with 12 active ports standard, while QW937B also ships with 12 active ports. Both support upgrade to 24 active ports via Ports on Demand license. The primary difference is SKU designation for inventory tracking and licensing management.

Can I upgrade from 12 to 24 ports without downtime?

Yes. The SN3000B features Ports on Demand (PoD) capability enabling upgrade from 12 to 24 active ports without downtime. The license activation is non-disruptive, allowing seamless capacity expansion. Additionally, hot code load supports firmware updates without requiring switch restart.

What port speeds does the SN3000B support?

The switch supports auto-negotiating speeds of 4 Gbps, 8 Gbps, and 16 Gbps. This flexibility enables mixed-speed SAN environments, allowing organizations to connect legacy 4/8 Gbps storage arrays alongside newer 16 Gbps infrastructure without requiring separate switches or complex zoning.

What is the aggregate bandwidth and fabric latency?

The SN3000B delivers 384 Gbit/sec endpoint bandwidth with 700 nanosecond fabric latency for locally switched ports. Forward Error Correction (FEC), enabled by default, adds 400 ns latency between E_Ports. ISL trunking supports up to eight 16 Gb/s ports per trunk for 128 Gb aggregate inter-switch bandwidth.

Does the switch include redundant power supplies?

The standard configuration includes a single power supply (80W with all 24 ports populated). Optional hot-swappable redundant power supplies are available as an upgrade, eliminating single points of failure for mission-critical SAN environments requiring high availability.

What management and diagnostic capabilities are included?

Management includes SSH v2, HTTP/HTTPS, SNMP v1/v3, Telnet, and in-band Fibre Channel connectivity. Diagnostics feature D-Port for physical link troubleshooting, FCPing for connectivity verification, Pathinfo (FCTraceroute), and Forward Error Correction (FEC) monitoring. SAN Network Advisor Professional provides centralized fabric management.

What is the physical form factor and power consumption?

The SN3000B is a 1U rackmount switch consuming 80 watts with all 24 ports populated with 16 Gb/s SWL optics. The compact 1U form factor maximizes data center density and cooling efficiency. AC input ranges from 85-264V at 47-63 Hz, supporting global power infrastructure.
