ProCurve PoE ports support the IEEE 802.3af standard. Some pre-standard devices have also been successfully tested with the ProCurve 3500yl and 5400zl switches. The Series 5400zl switches are used as a Power Sourcing Equipment (PSE) device providing PoE power to the Powered Devices (PDs) through the 24 Gig-T PoE module (J8702A), or the 20-port Gig-T plus 4 mini-GBIC PoE module (J8705A).

PoE power is provided on the Data Pairs (1&2 and 3&6). With ProCurve's Auto-MDIX feature, even though you may use a straight-thru cable for switch-to-switch connections, the PoE power will always be presented to the device on the 1&2 and 3&6 pins. 802.3af compliant Powered Devices accept power over either implementation scheme (data or unused pairs), and furthermore, are designed to be insensitive to the polarity of the DC power.

There is an ordering guide available that can help you determine your power supply needs, based on the PoE and redundancy demands of your environment.

ProCurve Networking Business recommends IEEE standards-based features for device discovery. To this end, the IEEE 802.1ab standard Link Layer Discovery Protocol (LLDP) is supported. It provides for device discovery for network management platforms and switch neighbor discovery. Yes, ProCurve uses IP addressing in the hashing decisions that determine which link a packet traverses after it is routed on the 6200, 5400, 5300 and the 3500.

Total ACEs in all ACLs: Depends on the combined resource usage by ACL, QoS, IDM, Virus-Throttling, ICMP, and Management VLAN features For more on this topic, refer to "Monitoring Shared Resources" in the Advanced Traffic Management Guide.

Yes. Ports operating at 1 Gbps or 10 Gbps speeds accept forward packets of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic. Note that on ports operating at 10 Mbps or 100 Mbps, the Maximum Transmission Unit (MTU) is fixed at 1522 bytes. The switch drops any inbound packets larger than the MTU allowed on a port.

No. If meshing is configured on the switch, the routing features (IP routing, RIP, and OSPF) must be disabled. The switch's meshing and routing features cannot be enabled at the same time. The ProCurve 5400zl, 3500yl, and 6200yl switches are compatible with the meshing feature on the 5300xl and 3400cl Series switches. There is no backward-compatibility mode for interoperation with a ProCurve Switch 4000M mesh.

The Series 5400zl Switches can be mounted with the optional Rail Mounting Kit (5070-0145) in any EIA- standard 19-inch telco rack or in an equipment cabinet such as a server cabinet. These rails stabilize the switch, enabling the rack or cabinet to be shipped without removing the switch. The rail mounting kit can be purchased through the HP Parts Web site at: http://www.hp.com/buy/parts.

Only revision "B" mini-GBICs are supported. This product requires ProCurve revision "B" or later mini-GBICs (product number ends with the letter "B", for example J4858B, J4859B). These switches do not support revision "A" mini-GBICs. Non-ProCurve mini-GBICs are not supported. Use of genuine products ensures that your network maintains optimal performance and reliability. Should you require additional ProCurve mini-GBICs, please contact a ProCurve sales representative or an authorized reseller.

The internal power supply of both ProCurve 3500yl models can provide 398W of PoE power, which is enough to provide full Class 0 power (15.4W) for up to 24 ports after some reserve conditions are met. There is an ordering guide available that can help you determine your power supply needs, based on the PoE and redundancy demands of your environment.

No. The chassis must be powered down prior to removal and replacement of the management module. A chassis without a management module will remain in a power-down state.

The power supply in the chassis generates both system power and PoE power. There are multiple power slots to allow for additional PoE power and/or redundancy. As long as the minimum number of power supplies for system power is installed at any given time, power supplies can be removed and replaced while the switch is operating. Caution should be used when doing this, however, because disconnecting power supplies interrupts PoE operation.

Stacking is primarily a feature for the 24-port and 48-port switches to create a port density comparable to a larger chassis switch. Since the ProCurve 5400zl switch already meets port density needs, it is not necessary to support the single IP address management between multiple 5400zl switches (stacking). You can use ProCurve Manager (PCM) software to manage multiple ProCurve 5400zl switches from a single user interface if this is desired.

No. If meshing is configured on the switch, the routing features (IP routing, RIP, and OSPF) must be disabled. The switch's meshing and routing features cannot be enabled at the same time. The ProCurve 5400zl, 3500yl, and 6200yl switches are compatible with the meshing feature on the 5300xl and 3400cl Series switches. There is no backward-compatibility mode for interoperation with a ProCurve Switch 4000M mesh.

The PoE status LED is a cumulative LED for all the ports/slots. It allows the user to see the PoE state of the switch at a glance without putting all the LEDs into PoE mode. The LED displays the highest level of failure/alert of all the slots/ports. So, if one of the ports is denied power and the port LED is flashing an alert in PoE mode, then the PoE status LED is also flashing an alert.

The ProCurve Switch 5400zl and 3500yl Series Switches support some pre-802.3af devices. This feature is enabled by default. It can be disabled using the no power pre-std-detect command. Yes. Ports operating at 1 Gbps or 10 Gbps speeds accept forward packets of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic. Note that on ports operating at 10 Mbps or 100 Mbps, the Maximum Transmission Unit (MTU) is fixed at 1522 bytes.

The PoE Consortium is a separate entity from the IEEE 802.3 Working Group and Power over Ethernet Plus Study Group. The UNH-IOL was a significant contributor to the development of the DTE Power via MDI standard (IEEE 802.3af-2003), attending and participating in most of the DTE Power via MDI Task Force meetings from the initial Call for Interest (CFI) in July 1999, through the final meeting in March 2003.

There are four types of switches that you'll need to concern yourself with. When you're starting out, you can ignore all of them! The dual rate switches let you choose how sensitive the control sticks are. Typically, "high rates" are used for aerobatics, which require a faster tumbles or pirouettes, and "low rates" are used for hovering, where slower, softer responses will give more precise control and smoother performance.

MSTP is backward-compatible with the RSTP-enabled and STP-enabled switches in your network. Use the following command to optimize this interoperability. ProCurveSwitch5406zl(config)# spanning-tree force-version < stp-compatible | rstp-operation | mstp-operation> excerpt from the parameter descriptions follows. For more detail, please see the Advanced Traffic Guide for the ProCurve Switch 5400zl, 3500yl, and 6200yl Series Products. rstp-operation: The switch applies 802.

Only revision "B" mini-GBICs are supported. This product requires ProCurve revision "B" or later mini-GBICs (product number ends with the letter "B", for example J4858B, J4859B).

Should you require additional ProCurve mini-GBICs, please contact a ProCurve sales representative or an authorized reseller.

Injector: Obviously, the PDs at the other end of the Cat 5 cable from the PSE need to be PoE compatible to then receive the current. Many manufacturers are now integrating this support into new products, but an alternative to PoE compliant PSE is to add a mid-span insertion device, sometimes called a mid-span insertion panel or power hub. This sits between the switch port and the PD.
