Deployment / Use Cases
This switch is well-suited for environments requiring a balance of port density, management capabilities, and quiet operation. The 18-port configuration provides sufficient connectivity for workgroups, while the managed features offer control over network traffic and security.
Typical deployments include small office networks where the switch serves as the core connectivity point for computers, printers, IP phones, and wireless access points. The SFP slots enable connections to other switches or network infrastructure over fiber, supporting network expansion or backbone links.
Office Workgroup Switch
Connect 16+ devices in a department or workgroup with Gigabit speeds, using the managed features to segment traffic between different teams or applications.
Quiet Environment Deployment
Install in libraries, medical offices, or conference rooms where fan noise would be disruptive, leveraging the fanless design for silent operation.
Network Expansion Node
Use the SFP slots to connect to other switches over fiber, extending network reach while maintaining copper connectivity for local devices.
Physical Profile
The switch features a compact 1U rack-mountable design with dimensions of 1.70 inches high, 11 inches wide, and 6.50 inches deep. This standard form factor fits easily into server racks or network cabinets alongside other equipment. The included rackmount hardware (two brackets and six screws) facilitates secure installation, while adhesive rubber feet provide stability for desktop use when rack mounting isn't required.

User Manual
FAQ
How many devices can I connect directly to this switch?
The Black Box LGB2118A-R2 provides 16 copper Gigabit Ethernet ports for direct device connections, supporting computers, printers, IP phones, wireless access points, and other network peripherals. The two SFP expansion slots allow for additional fiber connections or uplinks to other network equipment, bringing the total port count to 18.
What management features does this Layer 2 switch offer?
As a Layer 2 managed switch, the LGB2118A-R2 supports VLAN configuration for network segmentation, Quality of Service (QoS) for traffic prioritization, port monitoring, and web-based management interface. These features provide network administrators with control over traffic flow, security policies, and network performance monitoring.
Can I use fiber optic connections with this switch?
Yes, the switch includes two SFP (mini-GBIC) expansion slots that accept standard fiber optic transceivers. This allows connections using 1000Base-X technology for fiber uplinks to other switches or network infrastructure, extending network reach beyond the limitations of copper cabling.
Is this switch suitable for rack mounting?
Absolutely. The switch features a standard 1U rack-mountable form factor with dimensions designed for server racks and network cabinets. The package includes all necessary mounting hardware—two brackets and six screws—for secure installation in rack environments.
Does the switch require external cooling or produce noticeable noise?
No, the switch utilizes a fanless design that operates silently without moving parts. This makes it ideal for office environments, classrooms, or other spaces where noise reduction is important. The passive cooling system maintains proper operating temperatures through heat dissipation without audible fan noise.
