Final answer:
To troubleshoot the network connectivity issue on your office network, start by checking the network cables. If that doesn't work, try rebooting the switch. If the problem persists, contact your Internet Service Provider (ISP) for further assistance.
Step-by-step explanation:
If the partition light is displayed on a switch used on your office network and none of the users are currently able to use the network, the first thing you should do is check the network cables. Oftentimes, a loose or disconnected cable can cause connectivity issues. Ensure that all the cables are securely connected to the switch and the devices.
If checking the network cables doesn't resolve the issue, you can also try rebooting the switch. This can help reset any temporary glitches or errors that might be causing the problem.
Contacting your Internet Service Provider (ISP) should be your next step if the previous two steps didn't resolve the issue. They can provide assistance and check for any network outages or problems from their end.
