Unmanaged L2 Gigabit PoE-switch Cisco CBS110 16x 10/100/1000 RJ-45, 1U, 32 Gbit/s, 8192 MAC

Cisco CBS110 is an unmanaged Layer 2 Gigabit Ethernet switch with Power over Ethernet (PoE) support designed for small office and departmental networks. The unit provides 16 copper RJ‑45 ports operating at 10/100/1000 Mbps in full duplex, a switching capacity of 32 Gbit/s and an 8192‑entry MAC address table. Housed in a 1U rack‑mountable grey chassis, the switch complies with IEEE 802.3/802.3u/802.3ab and supports IEEE 802.1p and energy‑efficient Ethernet (802.3az) for reduced power consumption.

Advantages

The unmanaged design delivers plug‑and‑play operation without the need for configuration, allowing quick deployment in environments with limited IT support. Integrated PoE capability powers compatible IP phones, wireless access points and other PoE devices directly over Ethernet cabling. Gigabit ports and a 32 Gbit/s switching fabric provide full‑duplex performance for simultaneous traffic flows, while the 8192‑entry MAC table supports a typical small office device density. Energy‑efficient Ethernet and a compact 1U rack form factor make the switch suitable for space‑ and power‑conscious installations.

Suitable for

• Small office networks and branch locations
• Powering IP phones and PoE wireless access points
• Workgroups or departments requiring Gigabit connectivity
• Rack installations in wiring closets or compact server racks

• Power over Ethernet: PoE capable (delivers power to compatible devices)
• Energy efficiency: Supports IEEE 802.3az (Energy‑Efficient Ethernet)

How to use

Install the switch in a rack or place it on a flat surface according to available space. Connect each network device to the RJ‑45 ports using standard Cat5e or Cat6 cabling for Gigabit operation. If connecting PoE devices, ensure the powered devices are compatible with the switch's PoE capability and connect them to the appropriate ports; power is delivered automatically without additional configuration. Connect the uplink to your router or core switch to provide network and internet access. Because the switch is unmanaged, no configuration is required; devices obtain connectivity immediately once cables and power are connected.

Recommendations

Place the switch in a well‑ventilated rack space and use quality cabling (Cat5e or higher) to ensure reliable Gigabit links. Distribute PoE‑powered devices across ports to avoid exceeding any per‑switch power budget and verify device compatibility with standard PoE. For deployments requiring traffic prioritization or advanced management, consider pairing this unmanaged switch with upstream devices that provide QoS or monitoring.
