The following sections describe how to get your Switch powered-up and
ready for operation.
You can connect an Advanced Redundant Power System 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 2 Power Module.
Contact your supplier for details.
For full redundancy, the unit requires two Type 2 Power Modules
combined using a Type 2 Y-Cable. Contact your supplier for details.
ATTENTION: The Switch can only use a recommended Advanced
Redundant Power System output. Contact your supplier for details.
Use the following sequence of steps to power-up the Switch.
DANGER: It is essential that the mains socket outlet is installed near to
the unit and is accessible. You can only disconnect the unit by removing
the appliance coupler from the unit.
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. Table 2 shows possible colors for
the LED.
