Network switch MERCUSYS MS126CP 24x 10/100 Mbps PoE+ ports, 2x Gigabit RJ45 uplinks, rack-mount

The MERCUSYS MS126CP is a rack-mount network switch designed for small to medium office and surveillance deployments that require centralized PoE power and reliable wired connectivity. It provides 24 Fast Ethernet (10/100 Mbps) PoE+ ports and multiple Gigabit uplink options (2× Gigabit RJ45 and 2× Gigabit SFP slots) to aggregate traffic to the core network. The switch supports IEEE 802.3af/at standards, a per-port power output up to 30 W and a total PoE budget of 295 W, with Extend Mode enabling power and data transmission up to 250 m for remote devices.

Advantages

The MS126CP delivers a combination of centralized power delivery, flexible uplink choices and a straightforward plug-and-play deployment model. Its high PoE budget and per-port PoE+ support make it suitable for powering IP cameras, access points and VoIP phones. Built-in features such as Isolation Mode and Priority Mode help separate and prioritise traffic for more stable operation, while PoE Auto Recovery can automatically restart non-compliant powered devices to reduce manual intervention.

Suitable for

• Small to medium office networks requiring PoE-powered endpoints
• IP surveillance systems with multiple PoE cameras
• Wireless deployments using PoE access points
• VoIP phone systems that need centralised power and switching
• Edge aggregation and uplink to a core switch or router via Gigabit RJ45 or SFP

How to use

Install the MS126CP in a standard 19" rack using the supplied mounting brackets and connect the power cable to a 100–240 V AC source. Connect endpoint devices (IP cameras, access points, VoIP phones) to the PoE+ RJ45 ports; the switch will detect compliant devices and supply power automatically per IEEE 802.3af/at. Use the Gigabit RJ45 or SFP uplinks to connect the switch to your core network or router for bandwidth aggregation. No configuration is required for basic operation; the device is plug-and-play. For installations that require extended reach, enable Extend Mode to provide power and data up to 250 m, and consider Isolation or Priority Mode to manage traffic segmentation and service prioritisation for critical endpoints.

Usage recommendations

For reliable long-term operation, install the switch in a ventilated rack space, maintain ambient temperature within the specified -5 to 45 °C range, and ensure the total connected PoE load does not exceed the 295 W budget. Use appropriate Ethernet cabling (Cat5e or higher for Gigabit links) and SFP modules matching your fibre type for uplinks. When deploying many powered devices, plan port power allocation to avoid overloading and enable Priority Mode for latency-sensitive systems such as surveillance cameras.
