Front Panel Description Chapter 1 Product Overview S-PWR LED (Catalyst 3750-X) Table 1-11 S-PWR LED Color Off Green Blinking Green Amber Blinking Amber Description StackPower cable is not connected, or the switch is in standalone mode. An XPS cable is connected to the XPS 2200. Each StackPower port is connected to another switch or to an XPS 2200 (Catalyst 3750-X switches). This appears on the switch in a StackPower ring configuration that detects an open ring or has only one StackPower cable connected, and no connection to an XPS 2200. There is a fault: load shedding is occurring, a StackPower cable is defective, or administrative action is required. See the switch software configuration guide for information about configuring StackPower. The StackPower budget is not sufficient to meet current power demands. Master LED (Catalyst 3750-X) Table 1-12 Color Off Green Amber Master LED Description Switch is not the stack master. Switch is the stack master or a standalone switch. An error occurred when the switch was selecting the stack master switch, or another type of stack error occurred. Stack LED (Catalyst 3750-X) The stack LED shows the sequence of member switches in a stack. Up to nine switches can be members of a stack. The first nine port LEDs show the member number of a switch in a stack. Figure 1-4 shows the LEDs on the first switch, which is stack member number 1. For example, if you press the Mode button and select Stack, the LED for port 1 blinks green. The LEDs for ports 2 and 3 are solid green, as these represent the member numbers of other switches in the stack. The other port LEDs are off because there are no more members in the stack. 1-14 Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-02

Product Overview
Front Panel Description
S-PWR LED (Catalyst 3750-X)
Master LED (Catalyst 3750-X)
Stack LED (Catalyst 3750-X)
The stack LED shows the sequence of member switches in a stack. Up to nine switches can be members
of a stack. The first nine port LEDs show the member number of a switch in a stack.
Figure 1-4
shows
the LEDs on the first switch, which is stack member number 1. For example, if you press the Mode
button and select Stack, the LED for port 1 blinks green. The LEDs for ports 2 and 3 are solid green, as
these represent the member numbers of other switches in the stack. The other port LEDs are off because
there are no more members in the stack.
