2 Installation

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 should 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 air holes of switches.

-

Router shall work normally under correct voltage, so make sure the operating voltage

agrees with the voltage 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

electricity from damaging veneer.

2.1.2 Installation Site

To ensure a normal work environment, eMERGE EM-GE series should have the following
requirements for workplace:

-

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

of switch chassis.

-

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

systems.

-

Ensure that rack and working platform is firm enough to support the weight of a

switch and its accessories for installation.

-

Ensure rack and working platform is well earthed.

To ensure switches maintain a long-term stable work, the installation workplace should also
meet the following requirements:

Temperature/Humidity Requirements

To ensure the normal work and service life of switches, certain temperature 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 corrosion 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 switch; 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.

Humidity

10%～95%

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.

Concentration limit

DUST

Particle/m3

≤ 3 X 104 (No visible dust on the tabletop for three days)

Note: The dust particle size is ≥ 5 μm

Besides dust, there are rigorous limits on the content of harmful substances that can
accelerate the corrosion and aging of metals, such as salts, acids, and sulfides in the air in
the equipment room, and the equipment room must be protected against ingression of
harmful gases such as SO2, H2S, NH3, and Cl2. For the specific requirement, see the following
table.

Electromagnetic Susceptibility

Router may be affected by the interferences from outside the system, which will have an
effect on devices through conduction of capacitance 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 radio

transmitting station, radar transmitting station, high-frequency high-current devices.

eMerge EM-GE Ethernet Media Router Rev. A

nevion.com | 13

-

Electromagnetic shielding should be adopted when necessary, i.e. interface cables

use shielded cables.

-

Interface cables are required to be arranged indoors instead of outdoors to prevent

signal ports of devices from being damaged by over voltage and over current

generated from lightning.

Laser Use Safety

-

eMERGE EM-GE series are Class 1 laser devices.

-

Do not stare at the optical interfaces directly when the optional optical interfaces of

eMERGE EM-GE series are in operating mode, since light beam emitting from fiber

has high energy which may be harmful to retina.

2.1.3 Installation Tools

Prepare the following tools before installation:

-

Flathead screwdrivers

-

Phillips screwdrivers

-

ESD-preventive wrist strap

screwdriver to fix the power module.

The fan module of eMERGE EM-GE switch supports hot plug function, it is

convenient for maintenance and replacement online.

The fan module provides cooling function for the switch. If you need to replace a
failed fan module, it is recommended to complete the operating within three minutes

(prevent the temperature inside the switch is too high).

2.3 Grounding Connection

2.3.1 Grounding Connection

A noise filter is connected on the power input of switch, whose central earthing is connected
directly to the cabinet, which is called enclosure earthing (that is PE). This cabinet must be
well grounded to enable the safe flow of influence electricity and leakage into 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 grounding 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

and grounded.

3.1.1 10/100/1000 Ports

10/100/1000 Base-T Ethernet interface can use RJ-45 connectors. Its maximum transmission
distance is 100m. The transmission of 100Base-TX and 1000 Base-T needs to use CAT 5 or
enhanced CAT 5 twisted pair wires, or CAT 6 non-unshielded twisted pair wires. While the
transmission of 10 Base-T can use CAT 3 or CAT 4 twisted pair wires.

By default, 10/100/1000M auto-negotiation are enabled for RJ45 connectors for eMERGE
EM-GE Series Routing Router. By this setting, when two switches are connected, the
switches can automatically negotiate work environment and parameters to be used in
automatic configuration. If one switch does not support this feature, network administrators
or related personnel need to conduct configurations manually. See Configuration Manual for
specific manual configuration methods.

5 Router Software Loading

The traditional switch software loading is serial loading, but it is slow and time-consuming,
and it cannot realize remote loading and is inconvenient for operation. To address these
problems, TFTP module is introduced to switch to facilitate software loading and file
download via Ethernet. Specific operations are as follows:

Step 1: Enter uBoot operation mode

To enter uBoot operation mode, press the combined key Ctrl + b during the
switch startup when Press ctrl + b to stop autoboot: is prompted; startup information
is as follows:

Restarting system.
U-Boot 3.0.2 (Development build) (Build time: May 10 2011 - 17:14:19)
CN5010_CTC board revision major:1, minor:0, serial #:
OCTEON CN5020-SCP pass 1.1, Core clock: 500 MHz, DDR clock: 265 MHz (530 Mhz
data rate)
Board descriptor tuple not found in eeprom, using defaults
DRAM: 256 MB

Clearing DRAM...... done

Flash: 64 MB
BIST check passed.
Net: octeth0, octeth1
Press ctrl+b to stop autoboot: 3 – Press Ctrl + b to enter uBoot operation mode

Step 2: Identify a PC as loading server, connect the administration port of switch and
the PC with net line; set IP address of the PC and administration IP address of the
switch for the same network segment; specific operations are as follows:

-

Use the command help open_all to open all commands;

-

Use the command setenv ipaddr address to set the administration IP address of the
switch; the switch will copy image files to the switch from TFTP server using this

address;

-

Use the command setenv serverip address to set the IP address of TFTP server; the

switch will copy image files from this TFTP server;

-

Use the command ping to check if the switch communicates with the loading server;

-

Can use the command printenv to view the current environment variables of switch;

-

Can use the command saveenv to save the current environment variables of switch

to EPROM;

-

Can use the command reenv to restore the environment variables of switch to default

value.

Step 3: Run TFTP Server program on PC as a server, and set the directory where
loading files are located; uBoot file supposed to be upgraded is u_boot_v1.0.bin.

Step 4: Run the command upgrade_uboot u_boot_v1.0.bin to upgrade uBoot; here
the filename is u_boot_v1.0.bin.

Step 5: Run the command reset to complete the upgrade of uBoot.

6 Upgrade of Operating System

eMERGE EM-GE Series Ethernet Media Router can support new features and enhance
system performance without replacing hardware by upgrading the operating system.

Figure 29: Upgrade Operating System

Step 1: Copy the upgrading mirror to switch

1. 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.

Router# copy mgmt-if tftp://10.10.29.160/RouterOS-ma-

v3.1.12.it.r.bin flash:/boot/ RouterOS-ma-v3.1.12.it.r.bin

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

Step 2: Set the mirror that will be loaded when switch starts next time

1. After 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;

Router(config)# boot system flash:/boot/RouterOS-ma-

v3.1.12.it.r.bin

Step 3: View the mirror that will be loaded 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;

Router# show boot images

System image files list:
Current boot image version: 3.1.12
Create Time Version File name
================================================================
======
2011-01-01 15:03:30 3.1.11 RouterOS-ma-v3.1.11.it.r.bin

* 2011-05-28 10:08:38 3.1.12 RouterOS-ma-v3.1.12.it.r.bin

Among them, the files marked with * are image files that will be loaded when
switch starts next time.

7 Maintenance and Troubleshooting

7.1 Loading Failure Processing

After loading fails, the system will keep 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 addresses of Server
and Router, 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 contact 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.

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

Router 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 correctly.

-

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 faulty, 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:

Step 1: The power is normal.

Step 2: 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.

Step 3: 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: 9600, data bit: 8, parity: no, stop

bit: 1, flow control: NA, selecting terminal emulation: VT100.
