3.5 Stacking Scenario Examples

Use Ethernet cables when stacking the switches. See the following figures for example stacking scenarios using the
stacking module. The switches must form a closed ring in all scenarios.

STATUS
Blinking The system is rebooting and performing self-diagnostic tests.
ON The system is on and functioning properly.
OFF The power is off or the system is not ready/malfunctioning.
ON There is a hardware failure.
OFF The system is functioning normally.
Blinking The system is transmitting/receiving to/from a 10 Mbps Ethernet network.
ON The link to a 10 Mbps Ethernet network is up.
OFF The link to a 10 Mbps Ethernet network is down.
Blinking The system is transmitting/receiving to/from a 100 Mbps Ethernet network.
ON The link to a 100 Mbps Ethernet network is up.
OFF The link to a 100 Mbps Ethernet network is down.
Blinking The Ethernet port is negotiating in half-duplex mode and collisions are
occurring; the more collisions that occur the faster the LED blinks.
ON The Ethernet port is negotiating in full-duplex mode.
OFF The Ethernet port is negotiating in half-duplex mode and no collisions are
occurring.
