Features of the Cisco Small Business
Managed Switch
This section describes the exterior of the managed switches including
ports, LEDs, and connections.
Front Panel Ports
The ports and LEDs are located on the front panel of the switch.
RJ-45 Ethernet Ports—Use these ports to connect network devices, such
as computers, printers, and access points, to the switch.
MiniGBIC (if present)—The miniGBIC (gigabit interface converter) ports are
connection points for miniGBIC modules, so the managed switch can
uplink to other switches by using optical fiber.
• MiniGBIC ports are compatible with Cisco miniGBIC modules MGBSX1,
MGBLH1, MGBLX1, MGBBX1, MFELX1, MFEFX1, and MFEBX1, as well as
other brands of miniGBIC modules.
• MiniGBIC interface is a combination port, shared with one other RJ-45
interface. When the MiniGBIC is active, the adjacent RJ-45 port is
disabled.
• The LEDs of the corresponding RJ-45 port light to respond to the
miniGBIC interface traffic.
Front Panel LEDs
System LED—(Green) Lights steady when the switch is powered on, and
flashes when booting, performing self tests, and acquiring an IP address. If
the LED flashes Amber, the switch has detected a hardware failure.
LINK/ACT LED—(Green) Located on the left of the port. Lights steady
when a link between the corresponding port and another device is
detected. Flashes when the port is passing traffic.
NOTE The System and LINK/ACT LEDs are on each model of the switch.
The following LEDs are only present on switch models that have those
capabilities:
