Wrong or conflicting IP address:
Make sure that you are using the correct IP address of the switch. You
can verify the current IP address of the switch with your network
administrator. The System LED provides an indication of where the
switch received the IP address, see Section 4 for details.
Make sure that no other device is using the same IP address as the
switch.
No IP route:
If the switch and your computer are in different IP subnets, you need
one or more routers to route the packets between the two subnets.
Unusually long access time:
Due to the spanning tree loop detection logic, adding new connections
might take 30 to 60 seconds for the affected interfaces and/or LAN to
become operational.
Features of the Cisco Small Business

Smart Switch
This section describes the exterior of the smart switches including ports,
LEDs, and connections. Not all models will have all of the features
described.
Ports
RJ-45 Ethernet Ports—Use these ports to connect network devices, such
as computers, printers, and access points, to the switch.
• SFP (if present)—The small form-factor pluggable (SFP) ports are
connection points for modules, so the switch can link to other switches.
These ports are also commonly referred to as miniGigaBit Interface
Converter (miniGBIC) ports. The term SFP will be used in this guide.
• SFP ports are compatible with Cisco modules MGBT1, MGBSX1,
MGBLH1, MGBLX1, MGBBX1, MFELX1, MFEFX1, and MFEBX1, as well as
other brands of modules.
• Some SFP interfaces are shared with one other RJ-45 port, called a
combo port. When the SFP is active, the adjacent RJ-45 port is
disabled.
• The LEDs of the corresponding RJ-45 port flashes green to respond to
the miniGBIC interface traffic.
