Powering On the Switch
To turn on power to the switch, connect the AC power cable to the switch and then to the wall outlet.
Checking the Installation
After turning on power to the Summit 400-48t, 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
fast. The MGMT LED flashes until the switch successfully passes the POST.
If the switch passes the POST, the MGMT LED is blinking slowly (once per second). If the switch fails
the POST, the MGMT LED is amber. For more information on the LEDs, see “Summit 400-48 Switch
Rear View” on page 22.
