  • Power over Ethernet

    � Power over Ethernet or PoE technology describes a system

    to transmit electrical power, along with data, to remote

    devices over standard twisted-pair cable in an Ethernet

    network.

  • How to Deploy Power over Ethernet (PoE)

    Power Sourcing Equipment

    (PSE) (such as a Cisco

    Catalyst LAN Switch Port)

    There are two primary components of a PoE deployment:

    Powered Device (PD)

    Inserts power over the Ethernet cable

    Accepts and utilizes delivered inline power

  • Understanding Power Redundancy

    The 4500 can utilize two power supplies to work in either combined or redundant mode

    Switch

    © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential4500 Bootcamp 7

    In redundant mode, each power supply operates at 50% capacity and provides the same total power as a single power

    supply – if one fails, the backup reverts to providing 100% power

    In combined mode, each power supply operates at 83% - if one fails, then the

    running supply provides 100% of its power capacity

    Power Supply 1 Power Supply 2 Power Supply 1 Power Supply 2

  • Effects of Power Changes Redundant to Non Redundant

    When changing from redundant mode to non redundant mode, the following occurs

    1. System log and SYSLOG messages generated

    2. System power is increased to 83% for both supplies, this providing 167% of power supply total capacity

    3. If any modules were marked power deny due to insufficient power will be brought online if enough power is available

  • Effects of Power Changes Non Redundant to Redundant

    When changing from Non redundant mode to redundant mode, the following occurs

    1. System log and SYSLOG messages generated

    2. System power is decreased to power of one power supply - each power supply would normally revert to 50% operational capacity

    3. If module configuration exceeds available power, modules powered down from bottom slot upwards – inline devices are powered down from highest port to lowest port until power requirement is within available limits

  • Effects of Power Changes PSU removed Redundant configuration

    When adding a Power Supply to a redundant mode switch, the following occurs

    1. System log and SYSLOG messages generated

    2. System power is increased in first power supply to 100%

    3. There is no change in power status for modules as there is not a change in available power
