What is the PoE power budget and port support?

Provides 740W total PoE+ budget across 44 x 10/100/1000Base-T ports compliant with IEEE 802.3at, delivering up to 30W per port. Suitable for powering up to 44 full PoE+ devices simultaneously like APs and cameras without performance degradation.

What Layer 3 routing capabilities does it offer?

Supports RIP, RIP-2, static IP routing, and MLD with 2048 IPv4 and 256 IPv6 route entries. Enables inter-VLAN routing and basic L3 functions without external routers, ideal for segmented enterprise networks.

How does stacking work on this switch?

Optional stacking module allows up to 4 units to operate as one logical switch with shared management IP. Provides high availability, simplified configuration, and increased port density up to 192 PoE+ ports per stack.

What are the key performance specifications?

176 Gbps switching capacity, 130.9 Mpps throughput, and low latency via ASIC architecture. Supports 16000 MAC addresses, 9220-byte jumbo frames, and non-blocking wire-speed across all ports for demanding traffic.

What management interfaces are available?

CLI over SSH/Telnet, web GUI via HTTP/HTTPS, SNMP v1/2c/3, RMON, and out-of-band console. Integrates with HPE IMC for centralized monitoring and provisioning.
