THE

NSTALLATION
After turning on power to the Summit, the device performs a Power On Self-Test
(POST).
During the POST, all ports are temporarily disabled, the packet LED is off, the power
LED is on, and the MGMT LED ßashes. The MGMT LED ßashes until the Switch has
successfully passed the POST.
If the Switch passes the POST, the MGMT LED blinks at a slow rate (1 blink per
second). If the Switch fails the POST, the MGMT LED shows a solid yellow light.
For more information on the LEDs, refer to
Table 1-2
and
Table 1-4
.
