2.1

Preparation

for

Installation

2.1.1

Safety Precaution

The following precautions should be followed to avoid equipment damage and personal injury caused by

improper use:



Power source sh

ould be removed before cleaning switches. Do not use wet rags to wipe switches

and clean switches with liquid.



Do not place switches near water or in a wet environment, and prevent water or moisture from

entering switch chassis.



Do not place switches on an

unstable case or table, since the dropping would cause serious harm to

switches.



Maintain good indoor ventilation and clear airholes of switches.



Switches shall work normally under correct voltage, so make sure the operating voltage agrees with

the voltag

e marked on switches.



To reduce the risk of electric shock, do not remove its enclosure when a switch is working, and don’t

do so at will even if it is not powered.



Anti-static gloves must be worn when replacing interface board to prevent static electricit

y from

damaging veneer.

2.1.2

Installation

Site

To ensure a normal work environment,

9171

series routing switches should have the following requirements

for workplace:



Ensure that there are some spaces at the inlet and outlet of switch for heat dispersion of sw

itch

chassis.



Ensure that rack and working platform have good ventilation and heat dispersion systems.



Ensure that rack and working platform are firm enough to support the weight of a switch and its

accessories for installation.



Ensure rack and working pla

tform are well

grounded.

To ensure switches maintain a long

-

term stable work, the installation workplace should also meet the

following requirements:

2.1.3

Temperature/Humidity Requirements

To ensure the normal work and service life of switches, certain temp

erature and humidity should be

maintained inside switch rooms. Longtime higher humidity inside switch rooms may easily lead to poor

insulation or even electric leakage of dielectrics, and sometimes cause material changes in mechanical

features and corrosio

n of metal parts; if the relative humidity is lower, insulation pads could dry shrink to make

fastening screws loose. Meanwhile, in the dry climate, lower relative humidity could easily cause static

electricity which will impose harms to the circuit of swi

tch; higher temperature would be even more harmful:

longtime high temperature would accelerate aging process of insulation materials to greatly reduce the

reliability of switches and severely affect their service life.

Table 2

-1:Temperature/Humidity Requ

irements

2.1.4

Cleanliness Requirements:

Dust is a big hazard to the safe operation of switches. Indoor dust falling on the switch body can cause

electrostatic adsorption to make poor contact of metal

connectors or metal contacts. Especially when the

indoor relative humidity is lower, electrostatic adsorption is easily formed, which will not only affect equipment

service life, but also easily lead to communication failure.

2.1.5

Electromagnetic Susceptibility

Switches may be affected by the interferences from outside the system, which will have an effect on devices

through conduction of c

apacitance coupling, inductive coupling, electromagnetic wave radiation, common

impedance (including ground system) coupling and wires (power wire, signal wire and output signal wire, etc.).

The following attention should be paid to:



AC power supply system

is TN system, and AC power socket should be single

-

phase 3

-

wire outlet

with protective earth (PE) so that filter circuit on devices can effectively filter interference from

electric

grid

.



Places where switches work should be kept away from strong

-

power ra

dio transmitting station, radar

transmitting station, high

-

frequency high

-

current devices.



Electromagnetic shielding should be adopted when necessary,

i.e

. interface cables use shielded

cables.



Interface cables are required to be arranged indoors instead o

f outdoors to prevent signal ports of

devices from being damaged by

over voltage

and

over current

generated from lightning.

2.1.6

Laser Use Safety



9171

series of routing switches are Class 1 laser devices.



Do not stare at the optical interfaces directly when th

e optional optical interfaces of

9171

series of

routing switches are in operating mode, since light beam emitting from fiber has high energy which

may be harmful to retina.

platform. Such operation is relatively simple, and the only following aspects should be concerned during

operation

:



Ensure the working platform is stable and well

grounded

.



A 10 cm space around switch is left for heat dissipation.



Do not place heavy objects on switches.

2.2.3

Step 1:

Wear ESD

-

preventive wrist strap

, and confirm that the anti

-

static wrist strap is well earthed.



Step 2: Maintain correct up

-

down direction of power module (in lin

e with the positive direction of

characters, if turned upside down, the power module can not be inserted to the end due to structural

limit specially designed inside chassis), grip the handle on the front end of power module to be

Power Wire and Grounding Connection

2.3.1

AC Power Wire Connection



AC Power Socket (recomme

nded)

It is recommended that users use single

-

phase three

-

wire outlets with neutral point connectors or

multifunction microcomputer outlets. The neutral points of power must be grounded reliably in a building.

Generally, in wiring of building construction,

the power neutral points of electrical supply system in such

a building have been buried under the earth, so users need to confirm the power has been grounded.



AC Power Wire Connection

Step 1: Connect one end of the

ground

wire on enclosure included in a

switch to the

grounding

screw on back panel of the switch, and the other end is

properly grounded

.

Step 2: Insert one end of the power wire of the switch into the outlet on back panel of the

cabinet, and the other end into a

n

AC power outlet.

Step 3: Tur

n on the power switch, and check if the power indicator on front panel of the switch is

bright, which indicates that power connection is correct.

Note: The

ground

wire must be connected before switches are powered on.

2.3.2

Grounding Connection

A noise filte

r is connected on the power input of switch, whose central

grounding

is connected directly to

the cabinet, which is called enclosure

grounding

(that is PE). This cabinet must be well grounded to

enable the safe flow of influence electricity and leakage int

o the earth and increase the

anti-electromagnetic interference of switch.



Correct Way of Grounding is as follows:

Connect one end of the yellow and green PE cable of switch to the terminal of grounding bar and screw

up the fastening nut when there is a gr

ounding bar in the installation environment of Ethernet switches.

Note: it is an incorrect option to be grounded with fire mains and a lightning rod in a building, so the

ground wires of Ethernet switches should be connected to the works in switch room an

d ground

ed

.

When there is no grounding bar in the installation environment of Ethernet switches and grounding electrodes

are not permitted to bu

ry according to the conditions, if Ethernet switches are supplied with AC power, they

can be grounded through PE cables of AC power. At this point, PE cables of AC power should be confirmed

well grounded in the power distribution room or on AC supply trans

former side.

1: Upgrade Operating System

a.

Copy the upgrading mirror to switch

In the privilege mode of switch, use the command COPY to copy the mirror files on TFTP server

to the boot directory of switch flash;

Swtich#copy tftp://10.10.29.160/

CanogaOS

-

v1.2.5.fcs1

-

9171

.r.bin

flash:/boot/CanogaOS

-

v1.2.5.fcs1

-

9171

.r.bin

When copying, check if the switch has enough space; if the space is not enough, you can delete

redundant mirror.

b.

Set the mirror that will be loaded when switch starts next time

Aft

er copying the mirror to a relevant directory of switch, you can use the command boot to set

the mirror that will be loaded when switch starts next time;

Switch(config)#boot system flash:/boot/CanogaOS

-

v1.2.5.fcs1

-

9171

.r.bin

c.

View the mirror that will be lo

aded when switch starts next time

After setting the mirror that will be loaded when switch starts next time, you can use the command

SHOW

to check if the setting is valid;

Switch#show boot images

Maintenance and Troubleshooting

7.1

Loading Failure Processing:

After loading fails, the system will ke

ep running in the original version. At this time, users should re

-

check if

physical port connections are good firstly. If some ports are not connected, then re

-

connect them to ensure

that physical connections are correct, and begin re

-

loading. If physical

connections are correct, then check the

loading process information displayed on the super terminal to verify if there are input errors. If there are input

errors, correct them and re

-

load. For example, when using TFTP protocol, we enter incorrect IP addre

sses of

Server and Switch, name of loading software, do not specify the correct working path of correct TFTP server

and so on; if physical connections are good, and there are no input errors in the loading process but the

loading fails finally, please cont

act agents for help.

7.2

User Password Lost

If system password is lost or forgotten, the following method can be used to reset password:



Enter uBoot operation mode; see Chapter 5 for how to enter;



Input boot_flash_nopass command to start system in uBoot mode;

Note: After using boot_flash_nopass command, system will clear up the startup

-

config files; before

starting this operation, the startup

-

config files will be stored in flash: / startup

-

config.conf.old file.

7.3

Power System Troubleshooting:

Switch can judge

if its power system is faulty according to the PWR indicator on the front panel: when power

system works normally, the PWR indicator shall always keep lighting; when the PWR indicator is off, please

check if:



The power line of switch is connected correctl

y.EPS of switch matches the power required by switch

.



7.4

Configuration

System

Troubleshooting:

After the switch is powered on, if system is normal, the startup information will be displayed on the

configuration terminal; If the configuration system is fault

y, the configuration terminal may display no

information or hashes.



No information on the terminal: After power

-

on, if no display information on configuration terminal

appears, please check if:



The power is normal.



The cable of configuration port (Console)

is properly connected.



If no problems have been found after the above checks, it is possible that configuration cable is

faulty or the parameter setting of terminal (such as super terminal) are incorrect, please check

accordingly.



Troubleshooting for the

terminal displaying hashes:

If the configuration terminal displays hashes, it is probable that the parameter setting of terminal (such as

super terminal) are incorrect Please confirm the parameter setting of terminal (such as super terminal): baud

rate: 9

600, data bit: 8, parity: no, stop bit: 1, flow control: NA, selecting terminal emulation: VT100
