Checking for Correct
Operation
The following sections describe how to get your Switch 3300
powered-up and ready for operation.
You can connect a SuperStack 3 Advanced Redundant Power System
(part number 3C16071B) to the Switch. This unit, which is also known as
an RPS, is designed to maintain the power to your Switch if a power
supply failure occurs.
For normal redundancy, the unit requires one Type 2A Power Module
(part number 3C16074A).
For full redundancy, the unit requires two Type 2A Power Modules
combined using a Type 2 Y-Cable (part number 3C16078).
CAUTION: The Switch can only use a SuperStack 3 Advanced Redundant
Power System output.
Use the following sequence of steps to power-up the Switch.
CAUTION: The Switch has no ON/OFF switch; the only method of
connecting or disconnecting main power is by connecting or
disconnecting the power cord.
1 Plug the power cord into the power socket at the rear of the Switch.
2 Plug the other end of the power cord into your power outlet
The Switch powers-up and runs through its Power On Self Test (POST),
which takes approximately 12 seconds.
During the Power On Self Test, all ports on the Switch are disabled and
the LEDs light in the following sequence:
All unit LEDs light
Module LEDs light
Port Status LEDs light in a rapid cycle
When the POST has completed, check the Power/Self Test LED to check
that your Switch is operating correctly.
