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.

• Make sure that the ground is dry and flat and anti-slip measures are in place.

• Do not place the switch on an unstable case or desk. The switch might be severely damaged in case

of a fall.

• Keep the chassis and installation tools away from walk areas.

• Do not wear loose clothing, jewelry (for example, necklace), or any other objects that could get

caught in the chassis when you install and maintain the switch.

• To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch

is just powered off.

Examining the installation site

The A3100 v2 Switch Series must be used indoors. 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.

Electricity safety

• Clear the work area of possible hazards, such as ungrounded power extension cables, missing

safety grounds, and wet floors.

• Make sure that the operating voltage is as required.

• Locate the emergency power-off switch in the room before installation. Shut the power off at once in

case accident occurs.

• Unplug all the external cables (including power cords) before moving the chassis.

• Always check that the power has been disconnected.

ESD prevention

To prevent the electronic components from being damaged by the electrostatic discharge (ESD), you should not only take ESD measures where the switch is located, but also take the following precautions:

• Make sure the switch is well grounded. For how to ground the switch, see “Grounding the switch.”

• Always wear an ESD-preventive wrist strap when installing hot swappable modules.

Page 12

To use the ESD-preventive wrist strap:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to keep good contact with the skin.

3. Attach the ESD-preventive wrist strap to a post on the rack or ground it by using other methods.

Figure 14 Use an ESD-preventive wrist strap

(1) Rack post

Laser safety

The A3100 v2 switches are Class 1 laser devices.

WARNING!

Do not stare into any fiber port when the switch has power. The laser li may hurt your eyes.

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.

• High temperature can accelerate the aging of insulation materials and significantly lower the

reliability and lifespan of the switch.

Storage temperature –40°C to +70°C (–40°F to +158°F)

Page 13

CAUTION:

If condensation appears on the switch when you move it to a high-temperature environment, dry the switch before powering it on to avoid short circuits.

Table 3 Humidity requirements

Humidity Range

Operating humidity (noncondensing) 10% to 95%

Storage humidity (noncondensing) 5% to 95%

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 4 Dust concentration limit in the equipment room

Substance Concentration limit (particles/cu m)

EMI

Dust particles ≤ 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 5.

)

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.

Page 14

• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or

overcurrent caused by lightning strikes.

Grounding

Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD is essential to the operating reliability of your switch. Make sure that the resistance between the chassis and ground is less than 1.5 ohm. For more information about grounding the A3100 v2 Switch Series, see “Grounding the switch.”

Cooling

The cooling system of the A3100 v2 Switch Series varies by the switch model:

• Non PoE switches (fanless): There are openings on the left, right, and rear of the switch for natural

heat dissipation.

• PoE switches (built-in fans): Fans blow air from the left to the right of the chassis for heat dissipation.

See Figure 15.

Figure 15 Airflow through a PoE switch

For adequate heat dissipation, plan the installation site according to the airflow of your switch, and adhere to the following requirements:

• Leave a clearance of at least 10 cm (3.94 in) around the air intake and exhaust vents.

• Consider the heat dissipation of the installation site when determining air-conditioning

• Make sure the hot air generated by equipment at the bottom of the rack is not drawn in the intake

• The installation site has a good cooling system.

Space

For adequate ventilation and ease of maintenance, adhere to the following requirements:

• The clearance between the rack and walls or other devices is at least 1 m (3.28 ft).

• The headroom in the equipment room is no less than 3 m (9.84 ft).

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 with a grounding conductor buried in the earth ground

• Grounding the switch by using the AC power cord

Grounding cable

The A3100 v2 Switch Series 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. See Figure 26.

Figure 26 Grounding cable

Connecting the switch to the network

NOTE:

HP recommends that you perform basic confi

uration for your switch before connecting it to the network.

Connecting your switch to the network through twisted pair cables

The 10/100/1000Base-T ports of the A3100 v2 Switch Series use RJ-45 connectors and support MDI/MDI-X auto-sensing. Use category-5 or higher twisted pair cables to connect the Ethernet ports of your switch to the network.

To connect your switch to the network through twisted pair cables:

1. Make a straight-through or crossover Ethernet cable as needed.

2. Plug one end of the twisted pair cable into the RJ-45 Ethernet port of your switch.

3. Plug the other end of the twisted pair cable into the RJ-45 Ethernet port of the access device in the

network.

4. Check whether the LEDs of the RJ-45 Ethernet port are normal.

NOTE:

For more information about twisted pair cables, see the chapter “Appendix C Ethernet twisted pair cable.”

IMPORTANT:

• After connecting the switch to the network, you can use the ping or tracert command to check the

interoperability between the switch and the network. For more information, see

Series Command References

• If the port status LED on the switch flashes after you connect the switch to the network, and the switch

does not respond to your commands, the switch may be sending or receiving broadcasts. In this case, disconnect the switch to the network, re-configure the switch, and connect the switch to the network again.

Troubleshooting

TIP:

Clean your switch periodically because the noncompliant operatin switch failures. At the same time, check the installation environments against the requirements in “Preparing for installation.” Make sure the switch operates in a proper environment. Additionally, periodically perform the power-on test for the spare switches.

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 displays nothing or garbled text.

No terminal display

environments of switches may cause

If the configuration terminal displays nothing when the switch is powered on, verify the following items:

• The power supply is supplying power to the switch.

• 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:

• Baud rate—9,600

• Data bits—8

• Parity—none

• Stop bits—1

• Flow control—none

• Emulation—VT100

Power supply failure

The PWR/Power LED on the front panel shows whether the power supply system of the switch operates properly. The PWR/Power LED is steady green when the power supply system operates properly, and off when the power supply system fails.

To troubleshoot the power supply failure:

1. Check the power cable connections. If a power cable is loose, re-plug the power cable. If a power

cable is broken, replace it.

2. Check the power supply system. Make sure that the power supply system works properly and

outputs a voltage required by the switch.

Page 42

Interface failure

Each interface has a corresponding LED. When an interface connected to the network works properly, the corresponding LINK LED is on. If the LED of an interface connected to the network is off, the interface or the connecting cable may fail.

To troubleshoot the interface:

1. Check whether the switch works properly.

2. Check the cable connection of the interface. For how to correctly connect the cable to an Ethernet

interface with a RJ-45 connector or an optical interface, see the chapter “Connecting the switch to

the network.”

3. Check whether the cable fails. Use the cable to connect two interfaces of the same type that work

properly. If the LEDs of the two interfaces are on, the cable is normal. Otherwise, the cable fails.

4. If the interface uses a transceiver module, check that the interface type is compatible with the

transceiver module and the transceiver module is compatible with the cable.

5. If the interface uses a transceiver module, make sure that the current transceiver module works

properly by replacing a normal transceiver module.

6. If the interface is a combo interface (which comprises a copper port and a fiber port), make sure

that the interface used for connecting is activated for the combo interface. Then, use the combo enable { copper | fiber } command in interface view to activate the port, and check the LED.

NOTE:

• Each combo interface has one fiber SFP port and one copper Ethernet port. These two ports share one

port name and port view and cannot work simultaneously. When you activate one port (by using the combo enable { copper | fiber } command), the other port automatically shuts down.

• After an interface fails, if the switch has an idle interface of the same type, you can plu

the idle interface.

7. Check that the speed and duplex settings of the interfaces of a link are the same. Make sure that

two interfaces can work together.

PoE system failure

If a PoE-capable switch cannot supply power to a powered device (PD) attached to the switch, follow these steps to troubleshoot the PoE system:

1. Check that the power cable that connects the switch to the PD is a straight-through cable.

2. Make sure that the PoE-related configurations are correct. For how to configure PoE, see the

related configuration guide.

3. Check the temperature of the switch. The PoE-capable switch provides the overtemperature

protection mechanism. When the internal temperature of the switch exceeds 65°C (149°F), the switch performs self protection and disables PoE on all ports. When the internal temperature drops below 60°C (140°F), the switch enables PoE on all ports.

Appendix C Ethernet twisted pair cable

Ethernet twisted pair cable

An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly transmits analog signals and is advantageous in transmitting data over shorter distances. The maximum transmission distance is 100 m (328.08 ft).

RJ-45 connector

An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends.

Figure 46 shows the pinouts of an RJ-45 connector.

Figure 46 RJ-45 connector pinout diagram

Cable pinouts

EIA/TIA cabling specifications define two standards: 568A and 568B for cable pinouts.

• Standard 568A: pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4:

blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown solid.

• Standard 568B: pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4:

blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown solid.

Cable type

Based on performance

Ethernet cables can be classified into category 3, category 4, category 5, category 5e, category 6, and category 7 cable based on performance. In LANs, category 5, category 5e, and category 6 are commonly used.

Table 27 Description on commonly used Ethernet cables

Type Description

Category 5

Suitable for data transmission at a maximum speed of 100 Mbps, with a bandwidth of 100 MHz.

Type Description

Category 5e

Category 6

Based on pinouts

Ethernet twisted pair cables can be classified into straight through and crossover cables based on their pinouts.

• Straight-through: The pinouts at both ends comply with standard 568B. See Figure 47.

• Crossover: The pinouts at one end comply with standard 568B, and those at the other end comply

with standard 568A. See Figure 48.

To ensu re n ormal communica tion, the pins for sending data on one por t should c o rrespo n d to the pin s for receiving data on the peer port. When both of the ports on the two devices are MDI or MDIX, a crossover Ethernet cable is needed. A cross-over cable connects devices of the same type. When one port is MDI and the other is MDIX, a straight-through Ethernet cable is needed. A straight-through cable connects devices of different types.

If an RJ-45 Ethernet interface with MDI/MDIX autosensing enabled can automatically negotiate pin roles. The S3100V2 RJ-45 Ethernet interfaces support MDI/MDIX. By default, MDI/MDIX is enabled on a port.

Making an Ethernet twisted pair cable

To make an Ethernet twisted pair cable:

1. Cut the cable to length with the crimping pliers.

2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45

connector.

3. Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring

specifications.

4. Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure

the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the RJ-45 end and in the correct order.

5. Crimp the RJ-45 connector with the crimping pliers until you hear a click.

6. Repeat the above steps with the other end of the cable.

7. Use a cable tester to verify the proper connectivity of the cable.
