Powering On the SwitchSummit 300-48 switch
Connect the AC power cable to the switch and then to the wall outlet. The Summit 300-48 has the
additional requirement to turn the power switch on the back panel to the on position..
Checking the InstallationSummit 300-48 switch
After connecting power to the switch, the device performs a Power On Self-Test (POST).
During the POST, all ports are temporarily disabled, the port LED is off, and the MGMT LED flashes.
The MGMT LED flashes until the switch successfully passes the POST.
If the switch passes the POST, the MGMT LED blinks at a slow rate (one blink per second). If the switch
fails the POST, the MGMT LED shows a solid amber light.
