Introducing the Switch

The HP Switch 2510G-24 and Switch 2510G-48 are multiport Gigabit switches ideal for building high-performance small business networks. These switches are store-and-forward devices offering low latency for high-speed networking.

HP Switch 2510G-24 (J9279A)

HP Switch 2510G-48 (J9280A)

The Switch 2510G-24 and Switch 2510G-48 have, respectively, 24 or 48 autosensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports—either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC.

The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45, or mini-GBIC (SFP, small form factor pluggable) connectivity. If any of the mini-GBIC ports are used the corresponding RJ-45 port will be disabled.

1-1

Introducing the Switch

These switches are designed to be used primarily as a high-density wiring closet or desktop switch. These switches can directly connect computers, printers, and servers to provide dedicated bandwidth to those devices, and can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, the Switch 2510G Series devices offer full network management capabilities.

1-3

Introducing the Switch

Front of the Switch

■Four dual-personality ports. Use either the 10/100/1000Base-T RJ-45 connector, or install a supported HP mini-GBIC (SFP) for fiber-optic connections.

The RJ-45 connectors support the Auto-MDIX feature, which means you can use either straight-through or crossover twisted-pair cables to connect any network device to the switch.

Dual-Personality Port Operation. By default, the RJ-45 connectors are enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is removed, the associated RJ-45 port is automatically re-enabled.

Console Port

This port is used to connect a console to the Switch 2510G Series devices by using the supplied RJ45 to DB9 cable with the switch. The console port is located on the front of the Switch. This connection is described under “Connect a Console to the Switch” in chapter 2, “Installing the Switch.” The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

■Each port has a Link LED. If it is lit, the port has a link. If the Link LED is flashing, the port has failed its self test. The Fault and Test LEDs will be flashing simultaneously.

■If the Activity (Act) indicator LED is lit, each port LED displays activity information for the associated port—it flickers as network traffic is received and transmitted through the port.

■If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those ports that are operating in full duplex.

■If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows to indicate the connection speed for the port:

•Off = 10 Mbps

•Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle once every 0.8 sec.)

•On = 1000 Mbps

Reset Button

This button is used to reset the switch while it is powered on. This action clears any temporary error conditions that may have occurred and executes the switch self test.

Introducing the Switch

Back of the Switch

Clear Button

This button is used for these purposes:

■Deleting Passwords - When pressed by itself for at least one second, the button deletes any switch console access passwords that you may have configured. Use this feature if you have misplaced the password and need console access.

This button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, you should make sure the switch is installed in a secure location, such as a locked wiring closet.

■Restoring Factory Default Configuration - When pressed with the Reset button in a specific pattern, any configuration changes you may have made through the switch console, the web browser interface, and SNMP management are removed, and the factory default configuration is restored to the switch. For the specific method to restore the factory default configuration, see “Restoring the Factory Default Configuration” on page 11 in chapter 4, “Troubleshooting” of this manual.

■Auto-MDIX on all 10/100/1000 twisted-pair ports, meaning that all connections can be made using straight-through twisted-pair cables. Cross-over cables are not required, although they will also work. The pin operation of each port is automatically adjusted for the attached device: if the switch detects that another switch or hub is connected to the port, it configures the port as MDI; if the switch detects that an endnode device is connected to the port, it configures the port as MDI-X.

■automatic learning of the network addresses in each switch’s 8000address forwarding table, with configurable address aging value.

■automatically negotiated full-duplex operation for all 10/100/1000Base-T RJ-45 ports when connected to other auto-negotiating devices—the miniGBIC ports always operate at full duplex.

■easy management of the switch 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.

•HP Manager—an SNMP based, graphical network management tool you can use to manage your entire network. this product is included with your new switch.

■support for the Spanning Tree Protocol to eliminate network loops.

■support for up to 64 IEEE 802.1Q-compliant VLANs so you can divide the attached end nodes into logical groupings that fit your business needs.

Installation Precautions:

Follow these precautions when installing the Switch 2510G Series devices.

■ 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 either side of the switch (air vents) facing downward.

■ 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, 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.

■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. The 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).

■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. See Figure 2-1 for the air flow direction.

Summary

Follow these steps to install the switch. The rest of this chapter provides details on these steps.

1.Prepare the installation site (page 2-5). Ensure the physical environment is properly prepared, including having the correct network cabling ready to connect to the switch and having an appropriate location for the switch. Please see page 2-3 for some installation precautions.

2.Install mini-GBICs (optional—page 2-7). The switch has four slots for installing mini-GBICs. Depending on where you will install the switch, it may be easier to install the mini-GBICs first. Note that mini-GBICs can be hot swapped—they can be installed or removed while the switch is powered on.

3.Verify the switch passes self test (page 2-9). Plug the switch into a power source and observe the LEDs on the switch’s front panel that they indicate correct switch operation.

4.Mount the switch (page 2-11). The Switch 2510G Series devices can be mounted in a 19-inch telco rack, in an equipment cabinet, on a horizontal surface, or on the wall.

5.Connect power to the switch (page 2-14). Once the switch is mounted, plug it into the nearby main power source.

Installation Procedures

2. Installing or Removing mini-GBICs (SFPs)

You can install or remove a mini-GBIC or SFP from a mini-GBIC slot without having to power off the switch. Use only HP mini-GBICs and transceivers.

■The mini-GBIC slots are shared with the four 10/100/1000Base-T RJ-45 ports. If a mini-GBIC is installed in a slot, the associated RJ-45 port is disabled and cannot be used.

■The mini-GBIC ports operate only at full duplex. Half duplex operation is not supported, unless a 100-FX SFP transceiver is installed. The 100-FX SFP transceiver can operate at half duplex.

■Ensure the network cable is NOT connected when you install or remove a mini-GBIC.

When this manual was printed, the supported mini-GBICs include the following:

■HP Gigabit-SX-LC mini-GBIC (J4858B, J4858C)

■HP Gigabit-LX-LC mini-GBIC (J4859B, J4859C)

■HP Gigabit-LH-LC mini-GBIC (J4860B, J4860C)

■HP 100-FX SFP-LC Transceiver (J9054B)

Use only supported genuine HP mini-GBICs and transceivers with your switch. Non-HP mini-GBICs and transceivers are not supported, and their use may result in product malfunction. Should you require additional HP miniGBICs or transceivers, contact your HP Networking Sales and Service Office or authorized dealer.

Installing the mini-GBICs:

Remove the protective plastic cover and retain it for later use. Hold the miniGBIC by its sides and gently insert it into either of the slots on the switch until the mini-GBIC clicks into place. When the mini-GBIC is installed, the Link LED turns on for 2 seconds to verify correct installation.

The HP mini-GBICs are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port.

Installation Procedures

	Figure 2-2. Example of installing a mini-GBIC (SFP)
	Removing the mini-GBICs
N o t e	The network cable should be disconnected from the mini-GBIC before
	removing it from the switch.
	Depending on when you purchased your HP mini-GBIC, it may have either of
	three different release mechanisms: a plastic tab on the bottom of the mini-
	GBIC, a plastic collar around the mini-GBIC, or a wire bail.
	To remove the mini-GBICs that have the plastic tab or plastic collar, push the
	tab or collar toward the switch until you see the mini-GBIC release from the
	switch (you can see it move outward slightly), and then pull it from the slot.
	To remove the mini-GBICs that have the wire bail, lower the bail until it is
	approximately horizontal, and then using the bail, pull the mini-GBIC from the
	slot.
	Replace the protective plastic cover.
	Connecting Cables to mini-GBICs
	If you have any mini-GBICs installed in the switch, the type of network
	connections you will need to use depends on the type of mini-GBICs you have
	installed. See the table on page 2-5, and appendix B, “Switch Ports and
	Network Cables”, for the mini-GBIC cabling information.
	For mini-GBICs ports, and in general for all the switch ports, when a network
	cable from an active network device is connected to the port, the port LED
	for that port should go on. If the port LED does not go on when the network
	cable is connected to the port, see “Diagnosing with the LEDs” in chapter
	4, “Troubleshooting”.

Installation Procedures

3. 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 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.

		Connect power cord to
		the power connector
	Figure 2-3. Connecting the power cord
N o t e	The Switch 2510G Series devices do not have a power switch. They are
	powered on when the power cord is connected to the switch and to a power
	source. For safety, the power outlet should be located near the switch instal-
	lation.
	The switch automatically adjusts to any voltage between 100-240 volts and
	either 50 or 60 Hz. No voltage range settings are required.
	If your installation requires a different power cord than the one supplied with
	the switch, 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.

Installing the Switch

Installation Procedures

When the self test completes successfully:

•The Power and Fan Status LEDs remain on.

•The Fault and Test LEDs go off.

•The port LEDs on the front of the switch go into their normal operational mode:

–If the ports are connected to active network devices, the LEDs behave according to the Port LED View or LED Mode selected. The default view mode (Link), the LEDs should be on and the Mode LEDs will flicker if there is network activity.

–If the ports are not connected to active network devices, the Link and Act 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.

4. Mount the Switch

After the switch passes self test, you are ready to mount the switch in a stable location. The Switch 2510G Series devices can be mounted in these ways:

■in a rack or cabinet

■on the wall

■on a horizontal surface

Rack or Cabinet Mounting

The Switch 2510G Series devices are designed to be mounted in any EIAstandard 19-inch telco rack or communication equipment cabinet. Note that the mounting brackets have multiple mounting holes and can be rotated allowing for a wide variety of mounting options. Secure the rack in accordance with the manufacture’s safety guidelines.

For safe operation, read the Installation Precautions on page 2-3, before mounting a switch.

The 12-24 screws supplied with the switch are the correct threading for standard EIA/TIA open 19-inch racks. If you are installing the switch in an equipment cabinet such as a server cabinet, use the clips and screws that came with the cabinet in place of the 12-24 screws that are supplied with the switch.

Complete step 1, and plan which four holes you will be using in the cabinet and install all four clips. Then proceed to step 2.
