Power Connectors
A power supply that is installed in power slot A powers the switch. This power supply is a
field-replaceable unit (FRU). You can connect an optional FRU power supply in slot B to provide backup
power if power supply A fails. You can power the switch by using either an AC power supply, a DC
power supply, or a combination of the two.
Power Supply Connector
The power supply is an autoranging unit that supports input voltages between 100 and 240 VAC. Use the
supplied AC power cord to connect the AC power connector to an AC power outlet. See
Chapter 3,
“Connecting the Power Supply,” for instructions on how to connect the DC power.
Management Options
The switch offers several management options:
• Cisco IOS command-line interface (CLI)
You can fully configure and monitor the switch from the CLI. You can access the CLI either by
connecting your management station directly to the switch console port or by using Telnet from a
remote management station. See
Appendix C, “Configuring the Switch with the CLI-Based
Setup Program,” and refer to the Catalyst 3750 Metro Switch Command Reference on Cisco.com for
more information about using the CLI.
