1.3.2 IC3548-2GT
From the left to the right, the 3548 switch’s front panel contains the power LED and 2 exchanging LEDs; a
push button display mode converter; 48 10/100 ports, each with its own indicator light; and 2 Gigabit ports
(capable of using either the GBIC expansion ports [for fiber and copper GBICs] OR the 10/100/1000BaseT
Gigabit Ethernet ports), each with its own indicator light.
From left to right, the back panel (shown below) contains: a console port; a 12V DC jack for an external
power supply (IC35-RPS12, US part number 99-00777-01, sold separately); an AC socket (for primary
power) and a power switch.
1.4 Management and Configuration
There are three different methods by which a user can manage the switch: web, console/telnet, or with
SNMP software. You may prefer using a web browser to be able to configure the switch from any local or
remote computer, via the network, or you may wish to use a console for out-of-band management. SNMP is
an advanced management application, and is mostly automatic, giving you the information without having to
go through an interface step by step (Note: The switch is shipped with BootP support. See Appendix F for
more information on setting up BootP).
