Ethernet connection LEDs
• The green LED, labeled Link, illuminates when a valid connection to the network is
established at the maximum supported rate and blinks when there is activity on the port.
• The amber LED illuminates when an Ethernet connection is communicating at a slower rate.
• If neither LED is illuminated, connection speed is at a rate of 10 Mbps.
CO cables
Typically, CO cables feature two green LEDs: a POWER LED and a STATUS LED.
• The POWER LED indicates that the attached module is turned on.
• The STATUS LED indicates that a valid selection has been made to an LCM8/LCM16 switch.
Cascading LCM8/LCM16 switches
You can cascade other LCM8/LCM16 switch models to an LCM8 or LCM16 switch using a CAT
5 cable. In a cascaded system, each available target port on the main LCM8/LCM16 switch will
connect to a CO or ACI port on each cascaded switch. Each cascaded switch can then be connected
to a device with a CO cable.
To cascade multiple LCM8/LCM16 switches with an ACI port:
1. Using an appropriate length of CAT 5 cable, connect the ACI port on the cascaded switch to an
available port on your LCM8/LCM16 switch.
2. Repeat step 1 for all additional cascaded LCM8/LCM16 switches.
NOTE: The system will automatically “merge” the two switches together as one. All target devices connected to
the cascaded LCM8/LCM16 switch will display on the main LCM8/LCM16 switch target device list in the OSCAR
interface.
To cascade multiple LCM8/LCM16 switches without an ACI port:
1. Connect a CO cable to the local peripheral ports on the cascaded switch.
2. Using an appropriate length of CAT 5 cable, connect the CO cable from step 1 to an available
port on your LCM8/LCM16 switch.
3. Repeat steps 1 and 2 for all additional cascaded LCM8/LCM16 switches.
