H3C S5120V3-28P-PWR-LI 24-Port Gigabit PoE+ Layer 3 Managed Switch, 4 x SFP, 240W

Start with the task: connecting networks, adding wired device ports, or providing wireless coverage. A single installation may need more than one device type. Share a site diagram and device list so the proposed roles and connections are clear.

Check the access point location, building layout, obstacles and the number of active devices. Measure coverage where people actually work before choosing extra equipment; changing the internet package alone may not address a coverage problem.

List the devices to be connected and check each device’s power requirements against the switch’s per-port capability and total documented power budget. Also review uplink capacity and reserve ports for the expansion you actually expect.

Define which devices and services guests should be able to reach, then check whether the router, switch and access points support the required separation. Test the resulting access rules; a different wireless network name alone is not the acceptance test.

Provide floor plans, current equipment models, internet connections, cabling details and peak device counts. Describe the applications that matter most and the observed problem, such as disconnections or slow local file access.

Agree on the locations and representative workloads to test, then record wired and wireless results separately. Check connectivity, coverage and access rules during normal use, and retain a diagram and configuration backup for support.
