The Summit switch comes with four self-adhesive rubber pads. You can place up to four Summit 
switches on top of one another.

Apply the pads to the underside of each switch, and place a pad at each marked corner of the switch. 
Place the switches on top of one another, ensuring that the corners align.

After you supply power to the Summit switch, the switch performs a power-on self test (POST).

During the POST, all ports are temporarily disabled, the packet LED is off, the power LED is on, and 
the MGMT LED flashes. The MGMT LED flashes until the switch successfully passes the POST.

If the switch passes the POST, the MGMT LED blinks at a slow rate (one blink per second). If the switch 
fails the POST, the MGMT LED shows a solid yellow light.

See Chapter 4 for more information about Summit LED activity.

Removing and Installing Summit48si Power Supplies

This section applies to the Summit48si switch only. The Summit48si comes with a minimum of one 
power supply preinstalled at the factory. If you have a Summit48si switch, follow the instructions in this 
section for removing and installing the Summit48si power supplies.

To remove a Summit48si power supply:

Remove the power cable from the wall outlet and then from the switch.

Use a #2 Phillips screwdriver to unscrew the two retaining screws, as shown in Figure 47.
