=====Down 450=====

Quick Check: Common Causes of Down Radio

  * Outage
  * Radio not receiving power (POE Not plugged in correctly, bad cable, GFI outlet tripped)
  * Cables in the POE are loose and not getting a solid connection
  * Cables are not plugged in properly

====Checking The Tower====

First, determine what tower the customer is on. To do so you will need to click on "more" on the equipment for the radio.

Once you are on the equipment overview page you will want to look at the address range to see what tower the customer is on, shown below, the example is on PSA.

Once you know what tower they are on open **ctools** and go to the **Monitor and Manage** section on the left of the screen. select the default drop down and locate the tower the customer is on.

Once you click on the tower you will see the overview page displayed on the right side of the screen. You will want to check the device status section to make sure all the APs are online shown below.

**If any of these show offline for that tower reach out in slack immediately.**

If the Access Point is online and other radios are communicating with it, proceed to the next step.

====Power Cycling The POE====

Confirm the POE has power and that the cables are plugged into the correct ports.

  - Ethernet Cable going to the router wan port should be plugged into the Gigabit Data/Lan port of the POE. 
  - Cable going to the radio should be plugged into the data + power/POE port on the POE. 
 
Have the customer unplug the POE for 30-60 seconds. While it is unplugged (green light is out) have them reseat the cables into the POE one at a time to make sure they have a solid connection while it's unplugged. Once verified, have the customer plug the POE back in. The equipment should come back online within 2 minutes if this fixed the issue. 

If the Tower and AP are online but the radio remains down after the above troubleshooting you will want to begin the [[Inbound Escalations|Escalation Procdeure]].
