What is the PoE power budget?

The switch provides a 124W PoE power budget across 12 PoE+ ports, compliant with IEEE 802.3at. This supports powering devices like IP phones, access points, or cameras without additional injectors, ideal for SMB setups.

What are the performance specifications?

Switching capacity is 48 Gbps with throughput up to 35.7 Mpps (64-byte packets). It supports 8192 MAC addresses, jumbo frames up to 9216 bytes, and Energy Efficient Ethernet (IEEE 802.3az) for optimized performance and power use.

What is the form factor and mounting?

1U height rackmount (4.4 x 44.0 x 23.8 cm) for EIA-standard 19-inch telco racks with included hardware; also supports desktop mounting. Internal fixed AC power supply handles 100-240V at 50/60 Hz, max 160W.

Does it support energy efficiency features?

Yes, IEEE 802.3az Energy Efficient Ethernet reduces power in 100 Mb/s modes with compliant devices. Combined with auto-negotiation and flow control, it ensures efficient operation while maintaining full Gigabit capabilities.

What is the reliability rating?

MTBF is 69.9 years, indicating high durability. Per-port LEDs monitor status, activity, speed, and duplex, aiding quick diagnostics in network environments.
