Cisco Small Business SLM Series Smart Switch Installation Guide 3
G1-G2 — The switch is equipped with two autosensing gigabit Ethernet
network ports, which use RJ-45 connectors. The gigabit Ethernet ports
support network speeds of 10 Mbps, 100 Mbps, or 1000 Mbps. They can
operate in half- and full-duplex modes. Auto-sensing technology enables
each port to automatically detect the speed of the device connected to it
(10 Mbps, 100 Mbps, or 1000 Mbps), and adjust its speed and duplex
accordingly.
To establish a gigabit Ethernet connection using a miniGBIC port, you must
install a MGBT1, MGBSX1, or MGBLH1 gigabit expansion module and use
Category 5e cabling or fiber optic cabling. To establish a Fast Ethernet
connection using a miniGBIC port, you must install a MFEFX1 (100BASE-
FX) or MFELX1 (100BASE-LX) 100SFP transceiver and use fiber optic
cabling.
NOTE On the SLM248G, SLM248P, SLM224G, and SLM224P switches,
miniGBIC ports are shared with standard ports. If a miniGBIC
port is used, the shared standard port on the switch cannot be
used. The following table defines the shared port mapping of the
switch.
LEDs and Ports Common to all Switch Models
System — (Green) Lights up to indicate that the switch is powered on.
Blinks while the switch is performing a system self-test.
LNK/ACT — (Green) Lights up to indicate a functional network link through
the corresponding port to an attached device. Blinks to indicate that the
switch is actively sending or receiving data through that port.
Reset — Press and hold the Reset Button for less than ten seconds to
reboot the switch. Press and hold the Reset Button for more than ten
seconds to reset the switch’s settings to the factory defaults.
Ethernet (1-24 or 1-48) The switch is equipped with 24 or 48 auto-
sensing, Ethernet ports, which use RJ-45 connectors. The Fast Ethernet
ports support network speeds of 10 Mbps or 100 Mbps. They can operate
