Description

Black Box EMS1G48-S 48-Port Gigabit Unmanaged Network Switch

Overview

The Black Box EMS1G48-S is a 48-port, 10/100/1000 Mbps unmanaged Ethernet switch designed to expand network connectivity for workstations, IP cameras, or other network devices. Its plug-and-play operation simplifies deployment in environments requiring straightforward network segmentation and increased port density, such as small to medium-sized businesses or surveillance system backbones. The EMS1G48-S provides reliable data transfer for demanding applications without complex configuration.

Compatibility

This unmanaged switch is universally compatible with any Ethernet-enabled device operating on standard TCP/IP networks. It is suitable for connecting any IP cameras, NVRs, access control panels, or other network appliances that utilize 10/100/1000 Mbps Ethernet interfaces. It functions seamlessly with devices from major surveillance brands and standard IT networking equipment.

Installation Notes

The EMS1G48-S requires a standard AC power outlet for operation. It is designed for rack-mount installation using standard 19-inch rack hardware. Ensure adequate ventilation around the unit to prevent overheating, as continuous operation under load can generate heat. Connect devices using standard Cat5e or Cat6 Ethernet cables.
