Solutions
The Power LED is not lit. 
 
 
 
 
 
The Emergency Power LED is not lit. 
LED will turn off during system initialization. Check 
your power connection. Plug the power cord into 
another known working AC outlet. 
The primary power supply has failed. Install the 
optional emergency power supply and have the 
primary power supply serviced as soon as possible. 
This is normal. The emergency power supply LED will 
only light if the primary power supply fails and the unit 
takes over powering the switch. 
The 10/100/1000 port Link LEDs are not lit.
Check your cable connections. Make sure the 
connectors are seated correctly in each port, and that 
the correct type of cable is used in each port. See 
Chapter 2.6 Connecting to the Network for more 
information. 
The GBIC Link LED is not lit.
Check your GBIC connector. Make sure the cables 
are inserted correctly, with the Transmit (Tx) 
connector on one side of the link connected to the 
Receive (Rx) connector on the other side of the link. 
Cannot establish communication to another 
device (switch, router, workstation, etc.). 
• Make sure the Link LED for the port in use is
on. Make sure you are using the correct 
cable type. See Chapter 2.6 Connecting to 
the Network for more information on cabling 
procedures 
• Make sure the IP address, subnet mask,
and VLAN membership of the switch is 
correct 
• Make sure the switch port and the device
both are in the same VLAN
• Try to connect to a different port
Cannot auto-negotiate the port speed.
Make sure that auto-negotiation is supported and 
enabled on both sides of the link (in both 
devices).
