What is the PoE capability of the X435-8P-4S?

Provides 8x IEEE 802.3at PoE+ ports with 30W maximum per port and 124W total budget. Supports both 802.3af (15.4W) and 802.3at standards for powering Wi-Fi APs, IP phones, and cameras without external power injectors.

What uplink options does this switch offer?

Four unpopulated 1/2.5GBASE-X SFP ports supporting 100M/1G/2.5G fiber modules. Enables high-speed aggregation to core switches using multimode or single-mode transceivers for flexible campus and branch connectivity.

Is the switch suitable for quiet environments?

Yes, completely fanless design ensures silent operation ideal for offices, retail, and classrooms. Maintains thermal performance through efficient architecture without compromising reliability in 24/7 deployments.

What management features are available?

Runs ExtremeXOS with CLI via RJ-45 console, web GUI, SNMP, and cloud-based centralized management. Supports role-based policy, static routing, and comprehensive security for simplified operations across distributed sites.

What are the switching performance specs?

36 Gbps switching capacity and 26.8 Mpps forwarding rate with non-blocking full-duplex operation. Jumbo frame support to 9216 bytes optimizes throughput for video surveillance and storage traffic.

Can it be rack or wall mounted?

Yes, 1U 19-inch rack-mountable with wall-mount option. Compact 12.6 x 7.9 x 1.71-inch footprint fits constrained edge locations while providing enterprise-grade features.
