Chapter 2 Installation Preparations

2.1 Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

z Before cleaning the switch, unplug the power plug of the switch first. Do not clean

the switch with wet cloth or liquid.

z Do not place the switch near water or in a damp environment. Prevent water or

moisture from entering the switch chassis.

z Do not place the switch on an unstable case or desk. The switch might be

damaged severely in case of a fall.

z Ensure proper ventilation of the equipment room and keep the ventilation vents of

the switch free of obstruction.

z Connect the yellow-green protection grounding cable before power-on. z Make sure that the operating voltage is in the range labeled on the switch. z Do not open the chassis to avoid electrical shocks when the switch is operating or

just when the switch is powered off.

z When replacing interface cards, wear ESD-preventive gloves to avoid damaging

the cards.

2.2 Installation Site

The S5500-EI series must be used indoors. You can mount the switch in a rack or on a workbench, but make sure:

z Adequate clearance is reserved at the air inlet/exhaust vents for ventilation. z The rack or workbench has a good ventilation system. z The rack is sturdy enough to support the device and its accessories. z 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.

2.2.1 Temperature/Humidity

You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity may lead to bad insulation, electricity leakage, mechanical property changes, and metal corrosion. However, if the relative humidity is too low, captive screws may become loose as the result of contraction of insulation washers and static electricity may be produced in a dry environment to jeopardize the circuits on the device. A high temperature is the most undesirable condition, because it

2-1

Installation Manual H3C S5500-EI Series Ethernet Switches Chapter 2 Installation Preparations

accelerates the aging of insulation materials and thus significantly lowers reliability and service life of the switch.

For the temperature and humidity requirements of dif ferent models, refer to se ction

System Specifications of the S5500-EI Series” o n page 错误！未定义书签。.

“

2.2.2 Cleanness

Dust is a hazard to the operating safety of your device. The dust accumulated on the chassis can be adsorbed by static electricity and result in poor contact of metal connectors or metal contact points. Espe cially when the indoo r relative humidity is low, electrostatic adsorption is more likely to happen. This can not only shorten the service life of your device but also cause communications failures. The following table lists the dust concentration limit.

Table 2-1 Dust concentration limit in the equipment room

Substance Concentration limit (particles//m³)

Dust Note: The dust diameter is greater than or equal to 5 μm.

Besides dust, there are rigorous limits on the content of harmful substances in the air that can accelerate the corrosion and aging of metals, such as chloride, acid, and sulfide in the equipment room. The equipment room must be protected against ingression of harmful gases such as SO see the following table.

≤ 3 x 104 (no visible dust on the tabletop over three days)

, H2S, NH3, and Cl2. For specific requirements,

1.8

Table 2-2 Harmful gas limits in the equipment room

Gas Maximum concentration (mg/m3)

H2S 0.006 NH3 0.05 Cl2 0.01

2.2.3 Electromagnetic Susceptibility

The operation of your switch can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance (including the grounding system) coupling, and leads (power cables, signaling cables and output wires). To eliminate the interferences, pay attention to the following:

0.2

2-2

Installation Manual H3C S5500-EI Series Ethernet Switches Chapter 2 Installation Preparations

z As the AC power system is a TN system, use a single-phase three-wire power

socket with a protection earth (PE) to effectively filter interference from the power grid.

z Keep the device far away from radio transmitting stations, radar stations, and

high-frequency devices.

z Use electromagnetic shielding, for example, shielded interface cables, when

necessary.

z Route interface cables only indoors to prevent signal ports from getting damaged

by over-voltage or over-current caused by lightning strikes.

2.2.4 Laser Safety

The S5500-EI series are Class 1 laser devices.

Caution:

When an optional interface module or SFP module on the S550 0-EI series is operating, do not stare into the optical port because the laser light emitted from the optical fiber may hurt your eyes.

2.3 Installation Tools

z Flat-blade screwdriver z Phillips screwdriver z ESD-preventive wrist strap

Caution:

The installation tools are not shipped with the S5500-EI series.

2-3

Installation Manual H3C S5500-EI Series Ethernet Switches Chapter 3 Installation

Chapter 3 Installation

Caution:

When you ask your sales agent to maintain the switch, you must ensure that the dismantlement-preventive seal on a mounting screw of the H3C switch chassi s is intact. If you want to open the chassis, you should contact the agent for permission. Otherwise, you will bear any consequence resulting from your actions without permission.

3.1 Installing the Switch into a 19-Inch Cabinet

You can install the switch into a 19-inch standard cabinet in one of the following four ways:

z Use front mounting ears z Use front mounting ears and rear mounting ears z Use front mounting ears and a tray z Use front mounting ears and guide rails

The selection of installation methods depends on the width and dept h of the switch. For the installation methods, see

Caution:

Correctly connecting the grounding cable is crucial to lightning protection and electromagnetic susceptibility (EMS).

The power input end of the switch is equipped with a noise filter, whose central ground is directly connected to the chassis, forming the chassis ground (also kno wn as PGND). This chassis ground must be securely connected to the earth ground so that the faradism and leakage electricity can be safely discharged to the ground, enhancin g the EMS capability of the switch. Ground your switch as follows:

z When a grounding strip is available at the installation site, attach one end of the

yellow-green grounding cable of the switch to the grounding terminal on the grounding strip and fasten the captive nut. Note that the fire main an d lightning rod of a building are not suitable for grounding. The grounding cable of the switch should be connected to the grounding system in the equipment room.

Chapter 5 Boot ROM and Host Software Loading

Traditionally, the loading of switch software is accomplished through the serial port. This approach is slow, inconvenient, and cannot be used for remote real-time loading. To resolve these problems, the TFTP and FTP modules are introduced i nto the switch. With these modules, the software and files can be loaded through Ethernet port conveniently.

This chapter introduces how to load BootROM and host software into a switch locally and how to do this remotely.

5.1 Introduction to Loading Modes

You can load the software locally by using:

z XModem via the console port z TFTP via an Ethernet port z FTP via an Ethernet port

You can load the software remotely by using:

z FTP z TFTP

 Note:

The Boot ROM software version must match the host software version when you load the Boot ROM and host software.

5.2 Local Software Loading

If your terminal is directly connected to the switch, you can load Boot ROM and host software locally.

Before loading the software, make sure that your terminal is correctly connected to the switch to insure successful software loading.

5-1

Installation Manual H3C S5500-EI Series Ethernet Switches Chapter 5 Boot ROM and Host Software Loading

 Note:

The loading process of the Boot ROM software is the same as that of the host software, except that during the Boot ROM loading process, you must select different digits after entering the Boot Menu and the system gives somewhat different prompts. The following text mainly describes the Boot ROM loading process.

5.2.2 Loading Software Using XModem Through the Console Port

I. Introduction to XModem

XModem is a file transfer protocol that is widely used due to its simplicity and good performance. XModem transfers files via Console port. It supports two types of data packets (128 bytes and 1 KB), two check methods (checksum and CRC), and error packet retransmission mechanism (generally the maximum number of retransmission attempts is ten).

The XModem transmission procedure is completed by the cooperation of a receiving program and a sending program. The receiving program sends a negotiation packet to negotiate a packet check method. After the negotiation, the sending program starts to transmit data packets. When receiving a complete packet, the receiving program checks the packet using the agreed method. If the check succeeds, the receiving program sends an acknowledgement packet and the sending program proceeds to send another packet; otherwise, the receiving program sends a negative acknowledgement packet and the sending program retransmits the packet.

A.1 Installation of Lightning Arrester for AC Power (Socket Strip with Lightning Protection)

Caution:

Lightning arrester will not be shipped with the switch. You should purchase it by

yourself if needed.

If an outdoor AC power cord should be directly led to the switch, please serially connect

the lightning arrester for AC power (Socket Strip with Lightning Protection) before you

plug AC power cord into the switch, thus to prevent the possible damage to the switch

due to lightning strike. You can use cable clips and screws to fasten the lightning

arrester for AC power on the cabinet, workbench or the wall of equipment room.

Grounding and polarity indicator (red) : On means that the lines are wrongly connected (either the ground wire is not well connected, or the live and zero lines are wrongly connected). Please check the power supply circuit.

Normal operati o n indicator (green ): On means that the arrester works normally. Otherwise, it means that the protection circuit has been damaged.

Installation Manual H3C S5500-EI Series Ethernet Switches Appendix A Lightning Protection of the Switch

Caution:

z Make sure that the arrester is well grounded before using the lightning arrester for

power.

z After inserting AC power cord plug of switch into the socket of lightning arrester, if

the green LED is on and the red LED does not alarm, it means that the lightning

arrester of power is running and the function of lightning protection has taken effect.

z Pay adequate attention if the red LED is on. You should correctly locate the problem,

whether it is caused because the ground wire of the arrester is not well grounded or

because the live and zero wires are connected in reverse direction. You may check

that in the following way. When the red LED is on, use a multimeter to examine

polarity at the power socket of the arrester. If it is same to that of the power socket in

the equipment room, it means that arrester is not well grounded. If it is adverse to

that of the power socket in the equipment room, it means that the power socket of

the arrester is set to the reverse polarity. In this case, you should open th power

socket of arrester to correct polarity. After that, if the red LED still alarms, it means

that the arrester is not well grounded yet.

A.2 Installation of Lightning Arrester for Network Port

 Note:

Lightning arrester for network port is specially designed for the Ethernet port of

10/100M electrical interface (RJ-45 connector is adopted in this case).

Caution:

Lightning arrester for network port will not be provided along with the switch, and you

should purchase it by yourself if needed.

If an outdoor network cable should be led to the switch, please serially connect the

lightning arrester for network port before you plug this cable into the interface on the

switch, in case of the possibility that the switch may be damaged due to lightning strike.

II. Installation procedure

Step 1: Tear the protection paper at one side of the double faced adhesive tape apart

from the tape, and stick the tape on the surface of the arrester. Tear the protection

paper at another side apart from the tape, and stick the arrester onto the chassis of the

switch. The arrester should be attached on the chassis as close to the grounding screw

as possible.

Step 2: According to the distance to the grounding screw of the switch, cut the ground

wire of the arrester, and securely tightening its ground wire to the grounding screw of

the switch.

Step 3: Use the multimeter to measure whether the ground wire of the arrester contacts

well with the grounding screw of chassis.

Step 4: According to the instruction of arrester for network port, connect the arrester

with switch by the cables (be carefully with the cable direction. Outdoor network cable

should be inserted into the arrester‘s IN end, and the cable connected to the switch

should be inserted into the arrester’s OUT end). When you do that, observe whether

the arrester indicators normally display.

 Note:

The instruction of lightning arrester for network port contains the technical

specifications, installation and maintenance guide of the arrester. Please carefully read

it before installing the arrester.

Step 5: Use the nylon ties to bundle the cables neatly.

III. Installation precautions

Fully consider the following items in the installation process, otherwise, the

performance of the lightning arrester for network port will be affected:

z Lightning arrester for network port is installed in reverse direction. In practice, the

“IN” end should be connected to the outdoor network cable and the “OUT” end to

the network port on the switch.

z Lightning arrester for the network port is not well grounded. The ground wire for

the arrester should be as short as possible, so to ensure its good contact with the

grounding screw of the switch. After the connection, use the multimeter to confirm

that.

The lightning arrester for the network port is not installed completely. If the switch has

more than one network ports to interconnect with other devices via cables outdoor, you

should install lightning arresters for all these network ports for protection.
