Chapter 1 Product Overview
Management Options
The switch will start with only one power supply plugged in, but redundant failover and load sharing will not be available in this configuration. We recommend that you always connect both power supplies to separate AC or DC circuits for optimal power reliability.
For safety reasons, the AC power supply needs to be switched off and unplugged before it is removed from a chassis or inserted into a chassis. DC supplies should have power shut off from the source before they are removed.
If only one power supply will be used, you must use the blank faceplate supplied to cover the empty power bay.
Environmental Monitoring of the Power Supplies
Using the environmental monitoring and reporting functions, you can maintain normal system operation by resolving adverse environmental conditions prior to loss of operation.
Each power supply monitors its own temperature and output voltages. If conditions reach critical thresholds, the power supply might shut down to avoid damage from excessive heat or electrical current. The Cisco ME
Power Management for the Cisco ME 4924-10GE Switch
You can select AC or DC power supplies for your switch. The Cisco ME

A redundant power supply can be identified and diagnosed by a running system regardless of its input status. AC and DC supplies are interchangeable.

Management Options
The switch offers several management options:
•Cisco IOS
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. To create a partial configuration that will allow remote setup using the CLI, see Appendix C, “Initial Configuration for the Switch,” and refer to the Catalyst 4500 Command Reference on Cisco.com for more information about using the CLI for a more complete configuration.
