Sieťový switch ERNITEC ELECTRA-M232-1GB-460W — 1-Gb porty, 460 W budget, managed switch

ERNITEC ELECTRA-M232-1GB-460W is a managed 36-port Ethernet switch offering 1 Gbit/s connectivity on its user ports and a 460 W PoE power budget for connected devices. Designed for small to medium professional networks, the switch supports VLAN segmentation, advanced management protocols and centralized power delivery for IP endpoints such as access points, VoIP phones and cameras. Compliance with common IEEE standards ensures interoperability in mixed vendor environments while PoE features simplify installation of powered devices.

Advantages

The switch combines high port density with a substantial PoE power budget, enabling deployment of many powered devices without separate power injectors. Comprehensive management options (WEB, CLI, SSH, SNMP, RMON) and support for STP/RSTP/MSTP provide loop protection and improved network stability. Built-in security controls—IP/MAC/VLAN/port binding, DHCP Snooping, IP source guard and DAI—help protect the network at the edge. Multicast handling with IGMP snooping and QoS support improves performance for voice and video traffic.

Suitable for

• Small to medium enterprise LANs requiring centralized PoE delivery
• IP CCTV and security camera installations
• VoIP deployments and office telephony
• Wireless access point aggregation in campus or office environments
• Network segmentation and VLAN-based multi-tenant setups

Key specifications

• Multicast management: IGMP snooping v1/v2
• OAM support: 802.3ah remote loopback monitoring and control
• Security features: IP/MAC/VLAN/port binding, DHCP Snooping, IP source guard, DAI

How to use

Mount the switch in a standard 19" rack or place it on a flat surface following the manufacturer’s physical installation instructions. Connect uplink and endpoint devices using Cat5e or better Ethernet cables to the 1 Gbit/s ports. If deploying PoE devices, calculate power requirements to ensure the total does not exceed the 460 W budget and configure per-port PoE settings via the web interface or CLI. Create VLANs, configure STP settings and apply ACLs as required for traffic separation and resilience. Use SNMP, RMON or SSH for remote monitoring and troubleshooting.

Recommendations

For reliable PoE operation, plan powered device placement to avoid surpassing the 460 W budget and enable PoE time or watchdog features to schedule or reset power delivery when needed. Enable DHCP Snooping, IP source guard and port binding on edge ports to reduce unauthorized device access. Use VLANs and QoS to prioritise voice and surveillance traffic and enable STP variants to prevent loops in redundant topologies.
