24CHAPTER 2: INSTALLING THE SWITCH

When another Switch 4200 Series unit is added to the top of an established stack, no stack renumbering occurs. If however the unit being added takes the stack height above 4 then the ‘up’ port on the top unit of the existing stack will be disabled and its LED will flash green. You will then not be able to use that port again until the link is lost on that port.

When removing a Switch from a stack, note the following:

Removing a Switch 4200 Series unit from the bottom of an existing stack will cause the remaining stack to renumber.

Removing a Switch 4200 Series unit from the middle of an existing stack will cause the other Switches in the stack to divide into two stacks. Units below the unit removed will not renumber, units above will renumber.

Removing a Switch 4200 Series unit from the top of an existing stack will have no effect on the remaining stack.

If you are having problems, refer to “Solving Stack Formation Problems” on page 56.

The Power-up

The following sections describe how to get your Switch 4200 Series

Sequence

powered-up and ready for operation.

Powering-up the

Use the following sequence of steps to power-up the Switch.

Switch 4200 Series

 

1Plug the power cord into the power socket at the rear of the Switch.

2Plug 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 10 seconds.

Checking for Correct During the Power On Self Test, all ports on the Switch are disabled and Operation of LEDs the LEDs light in a set sequence.

When the POST has completed, check the Power On Self Test LED to make sure that your Switch is operating correctly. Table 6 shows possible colors for the LED.
