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 RJ-
45 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 non-
PoE+ 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,
■ 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 8000-
address 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—

Installation Precautions
WARNINGS ■ 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.
Cautions ■ 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 over-
current 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+
2-4
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.
Installing the Switch
Installation Procedures
8. (Optional) Connect a console to the switch (page 2-25). You may
wish to modify the switch’s configuration, for example, to configure an IP
address so it can be managed using a web browser, from an SNMP network
management station, or through a Telnet session. Configuration changes
can be made by using the included console cable to connect a PC to the
switch’s console port.
At this point, your switch is fully installed. See the rest of this chapter if you
need more detailed information on any of these installation steps.

Cabling Infrastructure - Ensure the cabling infrastructure meets the
necessary network specifications. See the following table for cable types and
lengths, and see appendix B, “Cabling and Technology Information” for more
information:
■ Installation Location - Before installing the switch, plan its location and
orientation relative to other devices and equipment:
• In the front of the switch, leave at least 7.6 cm (3 inches) of space for
the twisted-pair and fiber-optic cabling.
• In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space
for the power cord.
• On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling.
2. Verify the Switch Passes Self Test
Before mounting the switch in its network location, you should first verify it
is working properly by plugging it into a power source and verifying it passes
its self test.
1. Connect the power cord supplied with the switch to the power connector
on the back of the switch, and then into a properly grounded electrical
outlet.
