Verifying Port Status
Check each connection by viewing the port indicators on the base unit front panel.
Their staus is shown in the following table.
Verifying System Operation
Verify that the stack has at least one Management Module correctly installed and
operating. The “Mgmt” LED on the switch that contains the Management Module
should be on, indicating that the module is installed and operating correctly.
Verify that the stack connections are operating correctly. Each switch in the stack
has it’s own unique unit ID (a number from 1 to 4) displayed by the front-panel LCD
labeled “Switch ID.” If any switch in the stack displays a flashing or unstable unit ID
for more than 30 seconds, you should check the following items:
• Reset the stack by powering off all switches and then powering them back on.
• Be sure that all Stacking Modules are correctly installed in each switch’s lower-left
slot and the stacking cables are properly attached.
Verify that any optional modules are installed correctly. The Module 1 or Module 2
“Status” LEDs on the switch panel should be on, indicating that the modules are
installed and operating correctly.
Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any device is properly connected to the switch and
transmitting a link signal, the Link indicator will light up for the corresponding port. If
the Link indicator fails to light when you connect a device to the switch, check the
following items:
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.
