Question

How to troubleshoot a RUCKUS Switch that shows green SYST & PWR lights but the APs are completely off? 

Customer Environment

Symptoms

• SYST and PWR lights on the switch are solid green (normal).
• No port lights blinking on the front of the switch ports.
• Access Points have no lights (no power).
• Devices connected to the switch do not work.

Root Cause

Troubleshooting Steps

Figure 1: Switch looks normal (green SYST & PWR), but ports are off.

Figure 2: Access Point shows no lights because it’s not receiving power.

Figure 2: No lights on the Ceiling Access Points, as the Switch is unable to transmit power through its ports

Important initial step:

Before proceeding with the full troubleshooting process, please try the following step first. If the issue persists, continue with the Diagnosis & Resolution steps outlined afterward.

Step:
Connect the Access Point Ethernet cables to a different port on the Switch (any of the available 1–12 ports) to check if the Access Point powers on. (Refer to Figure 3)

Resolution

Follow these steps carefully to check and fix the issue.

Step 1: Find the Switch IP Address

To manage your switch, you need its IP Address (assigned by your Internet Service Provider’s router).

You can use a free IP Scanner tool on your computer or phone.
See guide: How to find the IP Address of the RUCKUS Devices (Switch and APs) using IP Scanner free applications

Step 2: Access the Switch via CLI (Command Line Interface)

Once you know the IP address:

1. Open a terminal/command prompt or use an SSH/Telnet client (like PuTTY).

2. Check guide: How to access the Command Line Interface (CLI) of the RUCKUS ICX-7150-C12P Switch

3. Connect to the RUCKUS Switch using the IP address.

It will look like:

ICX7150-C12 Switch>                  (SSH access)

telnet@ICX7150-C12 Switch>   (Telnet access if SSH fails)

Step 3: Check PoE Status

Type the following commands (press Enter after each):

ICX7150-24P Switch>enable

No password has been assigned yet...

ICX7150-24P Switch#show inline power

If all ports show as disabled/off, then the switch is not supplying power to APs. (Figure 4)

Figure 5: PoE displayed as disabled/off on all Switch ports

Step 4: Re-Enable PoE on All Ports

Run these commands:

ICX7150-24P Switch>enable

No password has been assigned yet...

ICX7150-24P Switch#configure terminal

Warning: 1 user(s) already in config mode.

ICX7150-24P Switch(config)#interface ethernet 1/1/1 to 1/1/12

ICX7150-24P Switch(config-mif-1/1/1-1/1/12)#inline power

Step 5: Verify

Run the command again to confirm:

show inline power

• All ports should now show as On. (Figure 6)
• APs will power back up (lights will appear).
