Netgear M4300-12X12F (XSM4324S) - Stackable Managed Switch with 24x10G including 12x10GBASE-T and 12xSFP+ Layer 3 Hardware Manual

Connect the end of the power cord to the power receptacle on the PSU.

Plug the AC power cord into a power source such as a wall socket or power strip.

When you apply power, the Power LED on the switch front panel lights. If your switch 
supports two PSUs, either the Power 1 LED or Power 2 LED on the switch front panel 
lights, depending on which PSU you installed.

If the Power LED does not light, make sure that the power cord is plugged in correctly and 
that the power source is good.

The following table lists symptoms, causes, and solutions for possible problems.

Power LED is off.

No power is received.

Check the power cable connections at the 
switch and the power source.

Ensure that all cables are used correctly and 
comply with the Ethernet specifications.

Combined 
speed/activity LED or 
an individual speed 
LED and an individual 
activity LED are off 
when the port is 
connected to a device.

Port connection is not working.

Check the crimp on the connectors and 
make sure that the plug is properly inserted 
and locked into the port at both the switch 
and the connecting device.

Ensure that all cables are used correctly and 
comply with the Ethernet specifications. 

Check for a defective port, cable, or module 
by testing them in an alternate environment 
where all products are functioning.

File transfer is slow or 
performance is 
degraded.

One possible cause is that a 
broadcast storm occurred and that 
a network loop (redundant path) 
was created.

Break the loop by ensuring that only one path 
exists from any networked device to any other 
networked device. After you connect to the 
switch web management interface, you can 
configure the Spanning Tree Protocol (STP) to 
prevent network loops.
