Extreme X435-8P-4S Gigabit Ethernet Switch
1. Product Overview
The Extreme X435-8P-4S is a compact, high-performance Gigabit Ethernet switch designed for distributed enterprises, branch offices, and small to medium-sized sites. It combines robust Layer 2 switching, Power over Ethernet (PoE+) support, and flexible uplink options in a fanless, silent design. Ideal for noise-sensitive environments, this switch offers reliable connectivity for IP phones, wireless access points, and IoT devices.
2. Key Features
- 8 x Gigabit Ethernet PoE+ ports (30W per port)
- 4 x 1G/2.5G SFP uplink ports (unpopulated)
- Fanless design for silent operation
- 124W total PoE budget
- Cloud management via ExtremeCloud™ IQ
- Fabric Attach for automated network provisioning
- Support for Audio Video Bridging (AVB)
3. Core Technologies
The X435-8P-4S runs on ExtremeXOS, supporting advanced features such as:
- IEEE 802.3at PoE+
- IEEE 802.3bz (2.5GBASE-X)
- IEEE 802.1 Audio Video Bridging (AVB)
- Role-based policy enforcement via ExtremeControl
- Fabric Attach for seamless integration with Extreme Fabric Connect
4. How It Works
The switch provides power and data connectivity over standard Ethernet cables. PoE+ ports deliver up to 30W per port to connected devices. Uplink SFP ports support fiber or copper transceivers for high-speed backbone connections. The device can be managed locally via CLI or web GUI, or centrally through ExtremeCloud IQ.
