Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
•
Before cleaning the switch, unplug all power cords from the switch. Do not clean the switch with wet
cloth or liquid.
•
Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•
Do not place the switch on an unstable case or desk. The switch might be severely damaged in case
of a fall.
•
Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch
free of obstruction.
•
Connect the yellow-green protection grounding cable before power-on.
•
Make sure that the operating voltage is in the required range.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch
is just powered off.
•
When replacing transceiver modules, wear an ESD-preventive wrist strap to avoid damaging the
units.
Examining the installation site
The HP 3100-48 v2 Switch must be used indoors. You can mount the switch in a rack or on a workbench,
but make sure:
•
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
•
The rack or workbench has a good ventilation system.
•
The rack is sturdy enough to support the switch and its accessories.
•
The rack or workbench is well earthed.
To ensure normal operation and long service life of your switch, install it in an environment that meets the
requirements described in the following subsections.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
•
Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
2
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
•
For the temperature and humidity requirements, see “Appendix A Technical specifications.”
Cleanness
Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure.
Table 1 Dust concentration limit in the equipment room
Substance
Concentration limit (particles/m³)
Dust
≤ 3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter ≥ 5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 2.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to
filter interference from the power grid.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•
Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
overcurrent caused by lightning strikes.
3
Cooling requirements
The built-in fan in the 3100-48 v2 switch blows air from the left to the right of the chassis for heat
dissipation, as shown in Figure 3.

Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
NOTE:
The power and grounding terminals in this section are for illustration only.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis
ground to the earth so the faradism and leakage electricity can be safely released to the earth to
minimize EMI susceptibility of the switch.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•
Grounding the switch with a grounding strip
•
Grounding the switch by using the AC power cord
•
Grounding the switch with a grounding conductor buried in the earth ground
Grounding cable
The 3100-48 v2 Switch is provided with a yellow-green grounding cable. One end of the cable has an
OT terminal, and the other end is naked and soldered, as shown in Figure 9.

in) of insulation sheath by using a wire stripper, and then insert the naked metal part through the
insulation covering into the end of the OT terminal. Secure the metal part of the cable to the OT
terminal with a crimper, and then cover it with the insulation covering. Then heat the insulation
covering with a blower to make it completely cover the metal part.
10
•
If you do not have an OT terminal, follow callout B in Figure 11 to make the connector: Peel the
insulation sheath by an appropriate length by using a wire stripper, and then bend the naked metal
part.
4.
Connect the made connector to the grounding post of the grounding strip, and then fasten it with
a hex nut, as shown in Figure 12.

Setting up an IRF fabric
You can use HP Intelligent Resilient Framework (IRF) technology to connect and virtualize 3100-48 v2
switches into a virtual switch called an “IRF fabric” or “IRF virtual device” for flattened network topology,
and high availability, scalability, and manageability.
This chapter includes these sections:
•

•
Planning IRF fabric setup
•
Configuring basic IRF settings
•
Connecting the physical IRF ports
•
Accessing the IRF fabric to verify the configuration

N/A
5.
Configure basic IRF
settings
For more information about IRF, see the HP 3100-48 v2 Switch IRF
Configuration Guide.
6.
Connect the physical IRF
ports
Connect physical IRF ports on switches. Use Ethernet cables, SFP transceiver
modules, and fibers to connect ports over a long distance, or use SFP IRF
modules to connect ports over a short distance.
All switches except the master switch automatically reboot, and the IRF fabric
is established.
Planning IRF fabric setup
Planning IRF fabric size and the installation site
Identify the number of required IRF member switches, depending on the user density and upstream
bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of
all member switches.
Plan the installation site depending on your network solution, as follows:
•
Place all IRF member switches in one rack for centralized high-density access.
•
Distribute the IRF member switches in different racks for dispersed access.
NOTE:
An IRF fabric can have up to nine 3100-48 v2 switches. As your business grows, you can plug an
3100-48 v2 switch into an IRF fabric to increase the switching capacity without any topology change or
replacement.
Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches in the IRF fabric.
An IRF fabric has only one master switch. You configure and manage all member switches in the IRF
fabric at the command line interface of the master switch.
24
NOTE:
IRF member switches will automatically elect a master. You can affect the election result by assigning a
high member priority to the intended master switch. For more information about master election, see the
HP 3100-48 v2 Switch IRF Configuration Guide.
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and
manage its members, and you must assign each IRF member switch a unique member ID.
Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology,
the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF
fabric changes to a daisy chain topology without interrupting network services.
You connect the IRF member switches through IRF ports. An IRF port is a logical interface for the internal
connection between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and
IRF-port 2. An IRF port is activated when you bind a physical port to it.
When connecting IRF member switches, you must connect the physical ports of IRF-port1 on one switch
to the physical ports of IRF-port2 on its neighbor switch.
The 3100-48 v2 switch can provide IRF connections through the GE Ethernet ports and GE SFP ports, and
you can bind several GE ports to an IRF port for increased bandwidth and availability.
NOTE:
• Figure 24 and Figure 25 show the topologies for an IRF fabric made up of three 3100-48 v2 Switch.
• The IRF port connections in the two figures are for illustration only, and more connection methods are
available.
Figure 24 IRF fabric in daisy chain topology
25
Figure 25 IRF fabric in ring topology
Identifying physical IRF ports on the member switches
Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
When using a combo interface for IRF connection, configure the fiber or copper port of the combo
interface as active. For how to configure the combo interface state, see the HP 3100-48 v2 Switch Layer
2—LAN Switching Configuration Guide.
Planning the cabling scheme
Use GE Ethernet twisted pairs, SFP IRF modules or SFP transceiver modules, and fibers to connect the IRF
member switches. If the IRF member switches are far away from one another, choose GE Ethernet twisted
pairs or the SFP transceiver modules with optical fibers. If the IRF member switches are all in one rack,
choose SFP IRF modules.
Table 11 lists the SFP transceiver modules and SFP IRF modules available for IRF connections.
The following subsections describe several IRF connection schemes and use SFP IRF modules or SFP
transceiver modules with optical cables for example. All these schemes use a ring topology.
Connecting the IRF member switches in one rack
NOTE:
This example uses nine switches.
You can connect the IRF member switches in one rack (see Figure 26), and Figure 27 shows the IRF fabric
topology.

connecting nine IRF member switches in different racks, and Figure 27 shows the IRF fabric topology.
Figure 28 Connect the IRF member switches in different racks
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see the HP 3100-48 v2 Switch Fundamentals Configuration Guide) to configure their member IDs,
member priorities, and IRF port bindings.
Follow these guidelines when you configure the switches:
•
Assign the master switch higher member priority than any other switch.
•
Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You perform
IRF port binding before or after connecting IRF physical ports depending on the software release.
•
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see the HP 3100-48 v2 Switch IRF
Configuration Guide.
Connecting the physical IRF ports
Connect IRF member switches with GE Ethernet cables, SFP IRF modules or SFP transceiver modules, and
fibers as planned.
28
NOTE:
Wear an ESD-preventive wrist strap when you connect SFP IRF modules or SFP transceiver modules and
fibers. For how to connect them, see the Pluggable SFP/SFP+/XFP Transceiver Modules Installation Guide.
Accessing the IRF fabric to verify the configuration
When you are finished configuring basic IRF settings and connecting IRF ports, follow these steps to
verify the basic functionality of the IRF fabric:
1.
Log in to the IRF fabric through the console port of any member switch.
2.
Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the
remote network management station can reach each other.
3.
Use Telnet, web or SNMP to access the IRF fabric from the network management station. (See the
HP 3100-48 v2 Switch Fundamentals Configuration Guide.)
4.
Check that you can manage all member switches as if they were one node.
5.
Display the running status of the IRF fabric by using the commands in Table 5.
Table 5 Display and maintain IRF configuration and running status
To do …
Use the command…
Display information about the IRF fabric
display irf

NOTE:
To avoid IP address collision and network problems, configure at least one multi-active detection (MAD)
mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more
information about MAD detection, see the HP 3100-48 v2 Switch IRF Configuration Guide.

Power system failure
The switch uses the system status LED (PWR) on the front panel to show how the power system of the
switch is operating. If the system status LED is off, a power supply failure has occurred. Check the
following items:
•
The power cord is well connected to the switch, and the AC receptacle on the switch and the AC
power receptacle are normal.
•
The external AC power supply system is operating properly.
•
The operating temperature of the switch is normal, and the power module has good ventilation
(over-temperature can cause a power module to stop working and enter the protection state).
NOTE:
If the problem persists, contact the HP technical support for help.
31
Fan failure
You can look at the system status LED and the seven-segment LED of a 3100-48 v2 switch to identify a fan
failure. If both LEDs are behaving as described in Table 6, a fan failure occurs.

NOTE:
To ensure the normal operation of the switch, contact the local sales agent or service engineer as soon as
possible when a fixed fan failure occurs.
Configuration terminal problems
If the configuration environment setup is correct, the configuration terminal displays booting information
when the switch is powered on. If the setup is incorrect, the configuration terminal would display nothing
or garbled text.
No terminal display
If the configuration terminal displays nothing when the switch is powered on, check that:
•
The power supply is normal.
•
The console cable is properly connected.
•
The console cable has no problem and the terminal settings are correct.
Garbled terminal display
If terminal display is garbled, check that the following settings are configured for the terminal, for
example, HyperTerminal:
•
