What is the PoE power budget and port allocation?

185W total PoE+ budget across 12 dedicated IEEE 802.3at PoE+ ports providing up to 30W each, plus 12 standard Gigabit ports and 2 SFP uplinks. Supports simultaneous powering of IP cameras, VoIP phones, and Wi-Fi APs without external power injectors.

What are the key performance specifications?

38.6 Mpps throughput with 52 Gbps switching capacity, <2 µs latency at 1000 Mbps and <7 µs at 100 Mbps for 64-byte LIFO packets. Non-blocking architecture with 16K MAC table and 10K jumbo frame support handles mixed SMB traffic efficiently.

What management features are available?

Web GUI enables VLAN (64), QoS (8 queues), IGMP snooping, STP variants, LACP link aggregation, and port mirroring configuration. SNMP v1-3 with RMON provides monitoring integration for centralized network management without requiring CLI expertise.

Is this switch suitable for rack mounting?

Yes, 1U half-width rack-mountable design fits standard 19-inch EIA racks. Includes rack ears and supports horizontal deployment in wiring closets or equipment racks typical for SMB office environments.

What SFP modules are compatible?

Dual SFP slots support 100/1000Base-X multimode/singlemode fiber transceivers or copper SFP for flexible 100M/1G uplinks to core infrastructure. HPE-branded modules recommended for optimal interoperability.

Does it support advanced L2 features?

Full Layer 2 feature set includes 802.1Q VLANs, 802.1p QoS, 802.3ad LACP, 802.1D/w/s spanning tree, IGMP snooping, and storm control. Suitable for access layer segmentation and redundancy in SMB networks.
