16CHAPTER 2: INSTALLING THE SWITCH

Placing Units On Top of Each Other

If the Switch units are free-standing, up to four units can be placed one on top of the other. If you are mixing a variety of Baseline and SuperStack units, the smaller units must be positioned at the top.

If you are placing Switch units one on top of the other, you must use the self-adhesive rubber pads supplied. Apply the pads to the underside of each Switch, sticking one in the marked area at each cor- ner. Place the Switch units on top of each other, ensuring that the pads of the upper unit line up with the recesses of the lower unit.

Supplying Power to the Switch

Power problems can be the cause of serious failures and downtime in your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network out- ages. 3Com recommends that you install power con- ditioning, especially in areas prone to black outs, power dips and electrical storms.

The unit is intended to be grounded. Ensure it is con- nected to earth ground during normal use. Installing proper grounding helps to avoid damage from light- ning and power surges.

Before powering on the Switch, verify that network cables and the power cable are securely connected.

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.

To power on the Switch:

1Plug the power cord into the power socket on the rear panel of the Switch. Refer to “(7) Power Supply” on page 12 for more information.

2Plug the other end of the power cord into a power outlet.

When the Switch is powered on, the Power LED lights up. If the Power LED does not light up, refer to “(5) Power LED” on page 12 for more information.

Checking for Correct Operation

After you power on the Switch, it automatically per- forms a power-on self-test (POST). During POST, the Power LED on the front panel of the Switch flashes green.

When POST is complete, the Power LED turns green. If the Power LED turns yellow after POST, it means that POST failed.

Table 8 summarizes the possible colors for the Power LED after POST.
