Problems
Possible Cause
Solution
Cannot connect to manage-
ment using RS-232 serial
connection
Be sure the terminal emulator program is
set to VT-100 compatible, 9600 baud rate,
no parity, 8 data bits and one stop bit
Use the included cable, or be sure that the
pin-out complies with a standard null-
modem cable
Cannot connect to switch
management using Telnet,
HTTP, SNMP, etc.
Be sure the switch has a valid IP address,
subnet mask and default gateway config-
ured
Check that your cable is properly con-
nected with a valid link light, and that the
port has not been disabled
Ensure that your management station is
plugged into the appropriate VLAN to
manage the device
If you cannot connect using Telnet or the
web, the maximum number of connections
may already be open. Please try again at
a later time.
No response from the termi-
nal emulation software
Faulty serial cable
Incorrect serial cable
Software settings
Replace the serial cable
Replace serial cable for a pin-to-pin
straight/flat cable
Reconfigure the emulation software con-
nection settings.
Response from the terminal
emulations software is not
readable
Faulty serial cable
Software settings
Replace the serial cable
Reconfigure the emulation software con-
nection settings.

Wrong or missing protocol
Faulty ethernet cable
Faulty port
Faulty module
Incorrect initial configuration
Configure the network address in the
workstation
Configure the network address in the
workstation
Configure the workstation with IP protocol
Replace the cable
