Introducing the Switch
HP ProCurve 2915-8G-PoE Switch (J9562A)
HP ProCurve 2615-8-PoE Switch (J9565A)
The HP ProCurve 2915-8G-PoE and 2615-8-PoE Switches are multiport
switches that can be used to build high-performance switched workgroup
networks. These switches are store-and-forward devices that offer low latency
for high-speed networking. The switches also support Power over Ethernet
(PoE) technologies.
1
Throughout this manual, these switches will be referred to as the Switch 29158G-PoE and the Switch 2615-8-PoE.
■ The Switch 2915-8G-PoE has 8 auto-sensing 10/100/1000Base-T RJ-45
ports with two Gigabit Uplink dual-personality ports (ports 9 and 10).
■ The Switch 2615-8-PoE has 8 auto-sensing 10/100Base-TX RJ-45 ports with
two Gigabit Uplink dual-personality ports (ports 9 and 10).
■ Power-over-Ethernet or PoE power (ports 1 through 8 only) - Both
switches support PoE technology, which 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 switches are designed with an internal PoE
power supply capable of providing 67 watts of PoE power. Each Switch
port can provide up to 15.4 watts (or 7.5 watts if all ports are used) of PoE
power to connected devices. For further information regarding PoE
power, see the PoE Planning and Implementation Guide, which is on
the ProCurve Web site at www.hp.com/go/procurve/manuals.
1-1
Introducing the Switch
Dual-personality ports use either the 10/100/1000Base-T RJ-45 connector, or a
supported ProCurve mini-GBIC (Small Form Factor Pluggable (SFP)) for
fiber-optic connection. By default, the RJ-45 connectors are enabled.
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 switches offer full network management capabilities.
Using ProCurve mini-GBICs, these products support optional network
connectivity with the following speeds and technologies:

Power Connector
The switches do not have a power switch. They are powered on when the
external AC/DC power adapter is connected to the switch and to a power
source. The external AC/DC power adapter supplies 48 volts DC to the switch
and automatically adjusts to any AC voltage between 100-240 volts and either
50 or 60 Hz. No voltage range settings are required.

Switch Features
Switch Features
The features of the switches include:
■ 8 auto-sensing 10/100/1000Base-T PoE or 10/100Base-TX PoE RJ-45 ports
with Auto-MDIX.
■ Two dual-personality uplink ports (1000Base-T RJ-45 or mini-GBIC).
■ Power over Ethernet (PoE) operation—the switches are IEEE 802.3af
compliant and provide up to 15.4W per port to power IP phones, wireless
access points, Web cameras, and more. For more information, see the PoE
Planning and Implementation Guide, which is on the ProCurve Web site
at www.hp.com/go/procurve/manuals.
■ The switches support some pre-standard PoE devices. However, the use
of a cross-over cable may be required.
■ 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, 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 10/100/1000 RJ-45
ports when connected to other auto-negotiating devices.
■ a “Save Power” mode option that keeps port LEDs turned off except for
when the LED Mode select button is pressed.
■ an automatic low-power mode for ports when a link is not present.
■ 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 256 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.

Installation Precautions
WARNING ■ 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.
■ Wall-mount the switch with network ports facing up (away from
the floor). Do not wall-mount the switch with the network ports
facing down (toward the floor) or ventilation ducts facing up or
down.
Cautions ■ Use only the AC/DC power adapter supplied with the switch for
connection to an AC power source.
■ 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 supplied power cord does not fit,
contact ProCurve 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 45°C (113°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.

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 2-5). 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 2-8). The switches can be mounted in a 19-inch
telco rack, in an equipment cabinet, on a wall, or on a horizontal surface.
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 2-17). Using the appropriate
network cables, connect the network devices to the switch ports.
2-4
6. (Optional) Install mini-GBICs (page 2-18). The switch has two or four
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 a console to the switch (page 2-20). You ma y
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.

Installation Procedures
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 AC/DC adapter’s power cord to the power connector on the
back of the switch, and then plug the AC/DC power adapter into a nearby
properly grounded electrical outlet.
Figure 2-1. Connecting the power cord
Note The switch does not have a power switch. It is powered on when the external
AC/DC power adapter is connected to the switch and the adapter power cord
to a power source. The external AC/DC power adapter automatically adjusts
to any voltage between 100-240 volts and either 50 or 60 Hz.
If your installation requires a different power cord than the one supplied with
the switch, be sure 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 supplied power cord does not fit, contact ProCurve Networking
support.

Installation Procedures
Caution Use only the AC/DC power adapter and power cord (if applicable), supplied
with the switch. Use of other adapters or power cords, including those that
came with other ProCurve Networking products, may result in damage to the
equipment.
2. Check the LEDs on the switch as described below.
Figure 2-2. Checking the LEDs
When the switch is powered on, it performs its diagnostic self test. Self test
takes approximately 50 seconds to complete.
LED Behavior
During the self test:
• Initially, all the switch and port LEDs are on. Most of the LEDs go off
and then may come on again during phases of the self test.
• For the duration of the self test, the Test LED stays on.
When the self test completes successfully:
•The Power and PoE LEDs remain on.
•The Fault, Locator and Tes t LEDs stay off.
•The Act LED remains on indicating the default port LED mode.
2-7
Installing the Switch
Installation Procedures
• The port LEDs on the front of the switch go into their normal opera-
tional mode:
– If the ports are connected to active network devices, the Link
LEDs stay on and the Mode LEDs behave according to the mode
selected. In the default mode (Act), the Mode LEDs should be
blinking indicating port activity.
– If the ports are not connected to active network devices, the Link
and Mode LEDs will stay off.
If the LED display is different than what is described above, especially if
the Fault and Test LEDs stay on for more than 60 seconds or they start
flashing, the self test has not completed correctly. Refer to chapter 4,
“Troubleshooting” for diagnostic help.
3. Mount the Switch
After the switch passes self test, it is ready to be mounted in a stable location.
The switch can be mounted in these ways:
■ in a rack or cabinet
