Cisco Business 240AC five-pack for small-business

The Cisco Business 240AC five-pack delivers IEEE 802.11ac Wave 1 and 2 access with MU-MIMO for small to medium businesses needing consistent coverage across multiple rooms. Each unit supports 2.4 GHz and 5 GHz bands with internal omnidirectional antennas rated at 4 dBi and 5 dBi peak gain. Two autosensing Gigabit Ethernet ports and PoE simplify cabling in ceiling or wall deployments. The pack suits offices, retail spaces and clinics that want a single SKU for multi-point rollout.

Sustained load behaviour with MU-MIMO and mesh

Under continuous client traffic the access points use 802.11ac data rates from 6.5 to 1733 Mbps on 5 GHz and 6.5 to 600 Mbps on 2.4 GHz, limited to 20 MHz channels and MCS 0 to 15. MU-MIMO serves multiple devices simultaneously, reducing airtime contention during video conferencing or 4K streaming. Mesh capability allows mixing with Cisco Business extenders to fill dead zones without additional controllers. The status LED reports boot, association and error states for quick health checks during peak hours.

Installation notes and common pitfalls

Mounting is straightforward using the supplied brackets and PoE power from a compatible switch or injector; no separate power adapter is required. The RJ-45 console port and USB 2.0 port are non-functional, so initial configuration must be done over the network interface. Ensure the PoE budget meets IEEE 802.3af/at on both Ethernet ports to avoid intermittent reboots. Operate within 0 °C to 50 °C and 10 % to 90 % non-condensing humidity for reliable service.

Features802.11ac Wave 1 and 2 capabilities with MU-MIMO technology
The IEEE 802.11ac standard delivers improved experience in typical environments, and more predictable performance for advanced applications such as 4K or 8K video, high-density high-definition collaboration apps, all-wireless offices, and Internet of Things (IoT). Supporting four spatial streams, MU-MIMO enables access points to split spatial streams between client devices, to maximize throughput.

Questions about this item

How much heat does each Cisco Business 240AC access point generate when running continuously at 0°C to 50°C?

The units operate between 0°C and 50°C (32°F to 122°F) with internal antennas and a single status LED, drawing power through PoE on the two Gigabit Ethernet ports.

What PoE standard must my switch support to power all five Cisco Business 240AC access points?

Each access point requires IEEE 802.3af/at PoE on its two autosensing 10/100/1000BASE-T ports, so the switch must deliver at least 802.3af power on every connected port.

Can the Cisco Business 240AC access points mesh with older Cisco APs that only support 802.11n?

Yes, mesh technology supports mixing Cisco Business mesh extenders or access points, and the radios cover 802.11n rates of 6.5 to 600 Mbps on both 2.4 GHz and 5 GHz bands.
