The Power-up
Sequence
The following sections describe how to get your Switch 3300 MM
powered-up and ready for operation.
Connecting a
Redundant Power
System
You can connect a SuperStack Advanced Redundant Power System (part
number 3C16071B) to the Switch. This unit, which is also known as an
ARPS, 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. For
full redundancy, the unit requires two Type 2A Power Modules combined
using a Type 2 Y-Cable.
Check with your supplier that you have the correct Power Modules and
cables for your ARPS unit.
CAUTION:
The Switch can only use a SuperStack Advanced Redundant
Power System output.
Powering-up the
Switch 3300 MM
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.
Checking for Correct
Operation
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
■
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. Table 4
shows possible colors for
the LED.
