Network Ethernet switch HP Enterprise 1 Gb 4-port 331T

HP Enterprise 1 Gb 4-port 331T is a compact unmanaged Ethernet switch that delivers four 1 Gbps RJ-45 ports for basic wired connectivity in small offices, home offices or network edge locations. The unit supports straightforward plug-and-play deployment with auto-negotiation and auto MDI/MDIX on each port, enabling reliable wired throughput for desktop PCs, printers and access points without requiring configuration. Its small form factor and standard metal housing make it suitable for shelf or desktop placement and integration into existing cabling infrastructure.

Advantages

The switch provides consistent 1 Gbps port speeds across all four ports, supporting full-duplex operation to maximize throughput for simultaneous send and receive traffic. Auto-negotiation and auto MDI/MDIX simplify installation and reduce the need for crossover cables. The unmanaged design eliminates the need for management overhead or setup, offering a stable, low-maintenance solution for basic network expansion. Built with a durable enclosure, the device is intended for continuous operation in typical office environments.

Suitable for

• Expanding wired ports for small offices or home workspaces
• Connecting desktop computers, network printers and wireless access points
• Providing a simple network edge switch for point-of-sale or kiosk systems
• Temporary or permanent network expansion where managed features are not required

Key specifications

• Port count: 4 x 10/100/1000 Mbps RJ-45 ports
• Operation: Unmanaged (plug-and-play)
• Duplex: Full- and half-duplex support with auto-negotiation
• Auto MDI/MDIX: Supported on all ports
• Form factor: Compact desktop/shelf mount with metal housing
• Power: External power adapter (AC to DC)
• Intended environment: Small office, home office, network edge

How to use

Place the switch on a stable surface near your network devices and an AC power outlet. Connect the supplied power adapter to the switch and plug it into mains power. Use standard Ethernet cables to connect computers, printers or access points to any of the four RJ-45 ports; the ports will auto-negotiate speed and link status. If integrating with an existing network, connect one port to your router or upstream switch. No configuration is required for basic operation; LEDs indicate link and activity status for each port.

Usage recommendations

For best performance, use Cat5e or higher-rated Ethernet cables for Gigabit links and ensure proper ventilation around the unit. Place the switch in a dry, dust-free area within the specified ambient temperature range. For networks requiring traffic management, security policies or remote monitoring, consider a managed switch instead of an unmanaged model like the HP Enterprise 331T.
