Introducing the Switch

The HP E2620 Switches are multiport switches that can be used to build highperformance switched workgroup networks. These switches are store-and- forward devices that offer low latency for high-speed networking. The nonPoE and PPoE+ switches support Redundant power supply (HP 600 RPS/ EPS). The E2620-PoE+ Switches also support Redundant and External Power Supply, and Power over Ethernet (PoE/PoE+) technologies.

Introducing the Switch

Throughout this manual, these switches will be referred to as the E2620

Switches and the E2620-PoE+ Switches.

■The E2620 Switches, have either 24 or 48 auto-sensing 10/100Base-TX RJ45 ports with four Gigabit Uplink ports, two RJ-45 and two mini-GBIC (Small Form Factor Pluggable (SFP)) slots.

The RJ-45 Gigabit Uplink ports are auto-sensing 10/100/1000Base-T. These ports operate independently, they are not dual-personality and do not support PoE+ power.

The E2620-PoE+ Switches incorporate two additional features. These switches offer two types of power, one for switch AC operating power, and the other for Power over Ethernet (PoE+) power:

1-2

Introducing the Switch

■Power-over-Ethernet or PoE+ power - PoE+ technology allows IP telephones, wireless LAN Access Points and other appliances to receive power as well as data over existing LAN cabling, without needing to modify the existing Ethernet infrastructure. The E2620-PoE+ Switches are designed with an internal PoE+ power supply capable of providing 364 watts of PoE power (126 watts on the E2620-24-PPoE+. The PPoE+ (Partial PoE+) switch provides 24 Ethernet ports, 12 of which can supply PoE+ power).

All of the Switch E2620-PoE+ ports can provide up to 30 watts (or 4 ports at 30 watts, or 8 ports at 15.4 watts on the E2620-24-PPoE+) of PoE+ power to connected devices. For further information regarding PoE/PoE+ power, see the HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, which is on the HP Web site at www.hp.com/ networking/support.

■Redundant and External Power Supply Support - The E2620 nonPoE+ and PPoE+ switches can be connected to an HP 600 Redundant and External Power Supply (J8168A), hereafter referred to as the 600 RPS/ EPS, for RPS power only. As an RPS unit, the 600 RPS/EPS will provide all the AC power necessary to keep the switch running should the switch internal AC power supply fail. The 600 RPS/EPS can not be used for EPS (PoE+) power for the E2620-PoE+ switches.

■The E2620 PoE+ switches can be connected to an HP 620 Redundant and External Power Supply (J8696A), hereafter referred to as the 620 RPS/ EPS, for RPS only. As an RPS unit, the 620 RPS/EPS will provide all the AC power necessary to keep the switch running should the switch internal AC power supply fail. The 620 RPS/EPS can not be used for EPS (PoE+) power for the E2620-PoE+ switches.

■Also, the E2620 PoE+ switches can be connected to an HP 630 Redundant and/or External Power Supply (J9443A), hereafter referred to as the 630 RPS/EPS, and receive redundant power from that unit. As an EPS unit, the 630 RPS/EPS can supply up to 398 watts of PoE power to the switch if the internal PoE power supply of the switch should fail. When used with the Switch E2620-48-PoE+, the additional EPS power can provide up to 30 watts per port for 48 ports. For further information regarding the RPS/ EPS PoE+ capabilities, see the HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, or the HP Redundant and/or External Power Supplies Installation and Getting Started Guide which is on the HP Web site at www.hp.com/networking/support.

These switches can be directly connected to computers, printers, and servers to provide dedicated bandwidth to those devices, and you can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, the E2620 Switches offer full network management capabilities.

Switch Features

RPS and EPS Input Port

The E2620 Switches support connectivity to three external power supplies denpending on the switch to be supported.

■The HP 600 Redundant and External Power Supply (J8168A) can be connected to:

•E2620-24 (J9623A)

•E2620-48 (J9626A)

•E2620-24-PPoE+ (J9624A)

For RPS power only. EPS power is not supported on these switches.

■The HP 620 Redundant and External Power Supply (J8696A) and the HP 630 Redundant and/or External Power Supply (J9443A) can be connected to:

•E2620-24-PoE+ (J9625A)

•E2620-48-PoE+ (J9627A)

The RPS functionality of these external power supplies provide redundant system power in case the switch’s internal power supply fails. The EPS functionality of the 630 provides additional PoE+ power. The E2620 Switches do not support EPS power from the 620 RPS/EPS. Also refer to the RPS/EPS Compatibility Matrix on page 1-4.

Power Connector

The E2620 Switches and E2620-PoE+ Switches do not have a power switch; they are powered on when connected to an active AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required.

Switch Features

The features of the E2620 Switches and E2620-PoE+ Switches include:

■24, or 48 auto-sensing 10/100Base-TX RJ-45 ports with Auto-MDIX.

■4 Uplink ports—two are 1000Base-T RJ-45 and two are mini-GBIC (SFP) slots.

1-13

Introducing the Switch

Switch Features

■Power over Ethernet (PoE/PoE+) operation—the E2620-PoE+ Switches are IEEE 802.3at compliant and provide up to 30W per port to power IP phones, wireless access points, web cameras, and more. For more information, see the HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, which is on the HP Web site at www.hp.com/ networking/support.

■The E2620-PoE+ Switches support some pre-standard PoE devices. However, the use of a cross-over cable may be required. For a current list see the FAQ page for the E2620-PoE+ Switch, which can be found on the HP Web site, www.hp.com/networking/support.

■Plug-and-play networking—all ports are enabled—just connect the network cables to active network devices and your switched network is operational.

■Auto-MDIX on all twisted-pair ports, 10/100 and 10/100/1000, meaning that all twisted-pair connections can be made using straight-through cables. Cross-over cables are not required, although they will also work.

■Automatic learning of the hardware addresses in each switch’s 8000address forwarding table, (with configurable address aging value).

■Automatically negotiated full-duplex operation for the 10/100 and 10/100/1000 RJ-45 ports when connected to other auto-negotiating devices—the mini-GBIC ports always operate at full duplex, unless a 100-FX SFP transceiver is installed. The 100-FX SFP transceiver can operate at half duplex.

■Easy management of the switches through several available interfaces:

•console interface—a full featured, easy to use, VT-100 terminal interface that is especially good for out-of-band switch management or for Telnet access to the switch.

•web browser interface—an easy to use built-in graphical interface that can be accessed from common web browsers.

•ProCurve Manager—an SNMP-based, graphical network management tool that you can use to manage your entire network.

■Support for the Spanning Tree Protocol to eliminate network loops

■Support for up to 512 IEEE 802.1Q-compliant VLANs so you can divide the attached end nodes into logical groupings that fit your business needs.

■Download of new switch software for product enhancements or bug fixes.

■Variable-speed fans to maintain cooling.

■Support for many advanced features to enhance network performance— for a description, see the Management and Configuration Guide, which is on the HP Web site at www.hp.com/networking/support.

Installation Precautions

■The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over.

Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices at the bottom and progressively lighter devices installed above.

■For safe operation do not install the switch with the side of the switch (with the fan vents) facing either downward or upward.

■If one of the following switches is to be mounted in a rack, you can use a rack kit, J9583A - HP X410 1U Universal 4-Post Rack Mounting Kit for the following switches only:

•J9085A HP Switch E2620-24

•J9088A HP Switch E2620-48

•J9086A HP Switch E2620-24-PPoE+

■Ensure the power source circuits are properly grounded, then use the power cord supplied with the switch to connect it to the power source.

■If your installation requires a different power cord than the one supplied with the switch, ensure the cord is adequately sized for the switch’s current requirements. In addition, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the switch. If the PoE+ device’s supplied power cord does not fit, contact HP networking support.

■When installing the switch, the AC outlet should be near the switch and should be easily accessible in case the switch must be powered off.

■Ensure the switch does not overload the power circuits, wiring, and overcurrent protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. Maximum ampere ratings are usually printed on the devices near the AC power connectors.

■Do not install the switch in an environment where the operating ambient temperature might exceed 55°C (131°F). This includes a fully-enclosed

rack. Ensure the air flow around the sides and back of the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling.

■Ensure all port covers are installed when the port is not in use.

Installing the Switch

Installation Procedures

Installation Procedures

These steps summarize your switch installation. The rest of this chapter provides details on these steps.

1.Prepare the installation site (page 2-6). Make sure the physical environment into which you will be installing the switch is properly prepared, including having the correct network cabling ready to connect to the switch and having an appropriate location for the switch. See page 2-3 for some installation precautions.

2.Verify the switch passes self test (page 2-6). Plug the switch into a power source and observe that the LEDs on the switch’s front panel indicate correct switch operation.

3.Mount the switch (page 2-9). The E2620 Switches can be mounted in a 19-inch telco rack, in an equipment cabinet, or on a horizontal surface.

The non-PoE+ E2620 Switches can also be wall mounted. See page 2-14 for wall mounting instructions.

The following switches can be rack mounted with rack kit, J9583A - HP X410 1U Universal 4-Post Rack Mounting Kit.

•J9623A HP Switch E2620-24

•J9626A HP Switch E2620-48

•J9624A HP Switch E2620-24-PPoE+

4.Connect power to the switch (page 2-15). Once the switch is mounted, plug it into the main power source.

5.Connect the network devices (page 2-15). Using the appropriate network cables, connect the network devices to the switch ports.

6.(Optional) Install mini-GBICs (page 2-17). The switch has two slots for installing mini-GBICs. Depending on where you install the switch, it may be easier to install the mini-GBICs first. Mini-GBICs can be hot swapped—they can be installed or removed while the switch is powered on.

7.(Optional) Connect an External Power Supply to the Switch (page 2-19). You may wish to use a 600 RPS/EPS, 620 RPS/EPS, or 630 RPS/EPS with your E2620-PoE+ Switches. To do so you must connect these external power supplies using the RPS or EPS cables supplied with these devices.
