Chapter 2 Physical Installation

Physical installation may only be performed by trained and authorized personnel. The electrical installation must adhere to local regulation requirements. The instructions for use must be followed at all times.

Installation considerations

• The device must not be accessible to passengers nor operational staff (excluding maintenan ce).

• The unit must be placed such that there is sufficient space for connecting the cables and removing the

protection cover.

• A minimum clearance of 50mm around the device should be ensured in order to avoid possible overheating. The space required by the connectors and cables can be up to 90mm, therefore sufficient space should be reserved for installing the system.

• The device must be secured firmly. A device that is inadequately fixed may cause danger to people or other equipment in the vehicle. The safety instructions of the vehicle must be followed rigorously.

• The device must be mounted inside an appropriate equipment cabinet.

• The device can be fixed in any orientation (vertical, transversal and longitudinal)

The DuraMAR-2150 anodized enclosure is built from two extruded aluminium parts. The outside dimensions excluding connectors are:

Length (mm) Width (mm) Height (mm)

External Connections

Only devices that meet SELV circuits (Security Extra Low Voltage) requirements in accordance with the EN60950 standard should be connected to the interfaces of the DuraMAR-2150.

All connection cable plugs must be screwed or locked to the housing. To maintain the Protection class, the connectors of the external cable must be adequately sealed and every

unused connector must be covered. Ensure that all connected cables, particularly the power cables, are positioned in areas where people or

machinery do not risk entanglement or being hit by the system. Vehicle power should only be connected after the installation of the system has been completed. All unused cables should be isolated or removed if possible. The cables must be shielded and the shields have to be grounded on both side s. The system must be grounded using the connection terminal in Rear Panel with the shortest possible

connection (max 20cm) using a low resistance cable.

Chapter 3 System Operation

This chapter illustrates the operation of the Eurotech Communication Controller (ECC) and its interaction with the CISCO 3200 ISR. If not otherwise stated, hereafter the word “system” will implicitly refer to ECC subsystem only.

Overview

The ECC is a standard x86-based system running a Linux kernel and a preinstalled application software (hereafter referred to as ECC firmware).

The ECC firmware provides a command line interface by which the user can obtain status information and perform configuration and maintenance operations. Available status information includes: network interface status, signal quality, availability of HSDPA service, internal temperatures as well as CPU parameters such as memory usage and CPU load. Some of this information can be also accessed using SNMP protocol.

The system is equipped with three different network interfaces:

• one 10/100 Mbps Ethernet interface (

eth0)

• one 3G cellular interface (

hsdpa0) used for providing HSDPA connectivity to the CISCO 3200 ISR

• one 2G cellular interface (

gprs0) available as a backup interface for accessing the system in case of

failure on the 3G interface

Operation Mode

The system is capable of operating in two modes:

• Routing Mode

• Bridging Mode

The mode of operation depends on the configuration of the HSDPA interface (see further

Routing mode

In Routing mode the ECC operates as a standard router connected to the CISCO 3200 ISR with an Ethernet link. In this mode a couple of private IP addresses are used on the link between ECC and the CISCO 3200 ISR with NAT (Network Address Translation) translation enabled on the wireless HSDPA interface.

This mode is suitable when there is no special requirement for the IP address used on the CISCO 3200 ISR router interface.

Bridging mode

In Bridging Mode the ECC will pass the carrier-assigned public IP address back to the CISCO 3200 ISR and assumes an address in the same subnet for preserving IP connectivity. This public IP address can be statically assigned to the CISCO 3200 ISR interface or made dynamically available using the DHCP protocol.

This mode is suitable for installations where a single public IP address negotiated on the wireless HSDPA link must be made available on the CISCO 3200 ISR router interface.

Page 16

DuraMAR 2150 – User’s Manual

DuraMAR-2150 configuration

The configuration of DuraMAR-2150 system involves the configuration of the CISCO 3200 ISR and ECC subsystems.

• The CISCO 3200 ISR subsystem can be configured using the console interface available on the panel side under the removable protection cover. The serial communication parameters must be set to

9600N81 (9600 baud, No parity, 8 bit data size, 1 Stop bit). There is no username or password defined

in the default configuration. Please refer to the documentation provided by CISCO for detailed configuration of the CISCO 3200 ISR devices.

• The ECC subsystem can be configured using the console interface available on the front panel under the service panel. The serial console communication parameters must be set as

115200N81 (115200

baud, No parity, 8 bit data size, 1 Stop bit).

Command Line Interface

The Command Line Interface (CLI) is a text-based user interface that provides a set of commands to configure the settings and monitor functions and status of the system. These commands and the way the CLI is used is very similar to the CISCO IOS® command interface making the use of CLI easy to adopt for experienced CISCO IOS® users.

The CLI is available to the user by connecting a terminal emulator to the serial console port interface (the one under the service panel) or by accessing the system through a SSH session. In both cases to access the CLI the user is asked to provide the following login information:

• username:

admin

• password:

admin

(default)

Once logged in, the user enters to a CLI session. The CLI will show a prompt and will wait for user input. The session is terminated when the user logs out.

A help command ('

?') is available at any time for a list of available commands or the required parameters that

must be typed as arguments of a given command. The CLI uses two different modes of operation:

• User Mode

• Configuration Mode

User Mode

Logging in to the device places the user in User Mode. In this mode the prompt consists of the host name assigned to the system followed by a pound sign (

#), as shown in the following example:

HSDPA-rt#

The default host name is empty so the initial prompt will be composed only of the pound symbol (#). The host name can be changed issuing the

hostname command.

To view the list of commands available in this mode, the user can type a question mark as shown in the following example:

HSDPA-rt# ? Show Show running system information Configure Enter configuration mode Copy Load or save configuration Debug Enable debugging information on terminal Undebug Disable debugging information on terminal Exit Exit from the cli

Page 17

DuraMAR 2150 – User’s Manual

Configuration Mode

The Configuration Mode is used to configure the system. This mode provides two sub-modes of operation: Global or Specific, depending on what part of the system the user is configuring. Specific mode allows

access to the configuration area of one of the system components, hardware or software, while Global mode allows access to global configuration parameters affecting the whole system.

To enter the Configuration Mode from User Mode issue the command:

configure. When entering

Configuration Mode you will find yourself in Global configuration mode. The system prompt changes to indicate that now you are in Global configuration mode as shown below:

HSDPA-rt(config)#

Commands entered in Configuration Mode update the running configuration immediately, as soon as the command is entered. However, these changes are not saved in the start-up configuration file until you issue the

copy running User mode command to save the configuration.

Entering a string identifying a specific system component while in Configuration Mode makes the user enter the Specific configuration mode. Commands available in this mode are specific for the component you are configuring.

As an example, to configure the Ethernet interface (

eth0), you will issue the command interface eth0.

Entering this command moves you to the specific configuration mode of the selected component and the prompt changes accordingly as shown in the following example below:

HSDPA-rt(config)# interface eth0 HSDPA-rt(config-if-eth0)#

While in Specific configuration modes such as in the example above, the commands available are only related to the specific component as shown below:

HSDPA-rt(config-if-eth0)# ? description Interface description IP IP Protocol config commands enable Enable the selected interface mobile Enable mobile subsystem on this interface mtu Change the mtu size for this interface nat Enable NAT services on this interface exit Exit from interface configuration mode

To exit from Specific configuration mode thus returning to Global configuration mode use the exit command. To end the configuration session issue the

exit command from Global configuration mode.

Using the no-form of commands

Almost every configuration command has a no-form that is used to reset or disable the specific configuration parameter/value.

For example the following commands:

HSDPA-rt(config-if-eth0)# enable HSDPA-rt(config-if-eth0)#

enable

will first enable (or activate) and then disable (or deactivate) the Ethernet interface.

Page 18

DuraMAR 2150 – User’s Manual

As another example, the following commands:

HSDPA-rt(config)# route 192.168.10.0 255.255.255.0 via 10.11.3.1 HSDPA-rt(config)#

route 192.168.10.0 255.255.255.0

will first set up a static route and then remove it.

Using commands history

The CLI stores a history of commands that you have entered. This feature is particularly useful for recalling long or complex command or entry strings. In order to recall commands from the command history buffer, use the up and down arrows keys. The history is not preserved across CLI sessions.

Configuration files

The configuration file looks like a plain text file that contains the commands used to define the functionality of the system. The commands included in the configuration file are executed automatically when the system is powered-on or when the user enters a command from the CLI in Configuration Mode.

There are two different types of configuration files:

• a start-up configuration file that is used during system start-up to configure the controller and that is stored in a non-volatile memory

• a running configuration file that contains the current active configuration

These two configuration files can be different. Configuration changes persist across CLI sessions, but will not be recorded in the start-up configuration file and will be lost as soon as the system is rebooted or switched off. To preserve the changes the user must save the running configuration on the system non-volatile memory using the

copy running command while in User mode.

The user can also save the running configuration to a file using the

copy running

file_name

command

and reload it later using the

copy

file_name

running command.

The user can switch between different configuration files using the

copy

file_name

startup command.

The complete syntax of the copy command is the following:

copy running

Copies current running configuration to the start-up configuration file

Loads the current start-up configuration file on to the current running configuration

copy startup

Copies the current running configuration file to the specified file

copy running

file_name

Copies the specified configuration file on to the current running configuration

copy

file_name

running

Copies the specified configuration file on to the start-up configuration file

copy

file_name

startup

The contents of the running or the start-up configuration file can be examined by issuing the

show running

and

show startup commands, respectively.

Page 19

DuraMAR 2150 – User’s Manual

Network interfaces general configuration

To configure a network interface the user must enter the Specific Configuration Mode for the given interface by issuing the

interface

if-name

command while in Configuration Mode. The prompt will change

accordingly. For example:

HSDPA-rt(config)# interface hsdpa0 HSDPA-rt(config-if-haspa0)#

The list of available interfaces can be obtained by issuing the show interface command.

Ethernet interface configuration

To configure the Ethernet interface the user must perform the following steps:

1. configure

2. interface

if-name

3. ip address

ip-address [mask] [link-gw]

4. enable

If you don’t specify any net-mask the system will use a standard class net-mask based on the IP address itself. The

link-gw

parameter is the IP address of the gateway used for outgoing traffic from this interface.

The available commands for configuring the Ethernet interface are the following:

description

Adds a text description for the interface

Assigns an IP address to the interface

ip address

addr [mask] [link gw]

Sets the IP Maximum Transmit Unit (MTU)

mtu

Forces the TCP Maximum Segment Size for the sessions entering or exiting from the interface

tcpmss

Enables Network Address Translation. The source address of all of the packets sent out through this interface will be changed to the IP address assigned to the interface itself

nat

Activates the specific interface

enable

HSDPA interface configuration

The configuration of the HSDPA interface affects the system’s operation mode.

Router Mode

In Router Mode the system operates as a standard router: all the traffic that comes in from the Ethernet interface is routed through the 3G wireless link.

To configure the system for operating in Router Mode, the

hsdpa0 interface must have the NAT service

enabled and must be used as default route for the outgoing traffic. The IP connectivity between the CISCO 3200 ISR and the ECC must be properly configured and the IP address assigned to the

eth0 interface of the

ECC must be configured as default gateway on the CISCO 3200 ISR. The steps required to configure the interface for Router Mode are as follows:

1. configure

2. interface

if-name

3. apn

network_name

4. defaultroute

Page 20

DuraMAR 2150 – User’s Manual

5. nat enable

6. enable

7. exit

8. exit

Please note that the exit command must be issued twice. An example of a Router Mode configuration follows:

Version: 1.0.0 - $Rev: 317 $ ! hostname HSDPA-rt interface eth0 ip address 172.16.10.1 255.255.255.252 enable ! interface hsdpa0 ip address negotiated enable apn web.omnitel.it mode auto defaultroute nat enable

The CISCO 3200 ISR must be configured accordingly as in the example below:

! interface FastEthernet0/0 ip address 10.200.1.24 255.255.0.0 duplex auto speed auto !

..........

! interface FastEthernet1/3 ! interface Vlan1 ip address 172.16.10.2 255.255.255.252 ! ! ip route 0.0.0.0 0.0.0.0 172.16.10.1

Note that the FastEthernet 1/3 interface is a switched interface so the IP address must be assigned to a VLAN interface and can’t be directly assigned to the Ethernet interface as for

fa0/0 (which is a fully routed

interface).

Bridge Mode

In Bridge Mode the system will pass the carrier-assigned public IP address of HSDPA interface back to the CISCO 3200 ISR allowing the latter to use this address as it was directly assigned to its Ethernet interface.

The steps required to configure the interface for Bridge Mode are:

1. configure

2. interface

if-name

3. apn

network_name

4. pppbridge

if-name

dynamic | static

5. enable

6. exit

7. exit

Bridge Mode can be dynamic or static.

Page 21

DuraMAR 2150 – User’s Manual

Dynamic Bridge Mode

In Dynamic Bridge Mode the carrier-assigned public IP address is made available to the CISCO 3200 ISR FastEthernet interface using the DHCP-protocol; then the first (.1) or last (.254) IP address of the network that this address belongs to is automatically assigned to the ECC Ethernet interface in order to guarantee local IP-connectivity.

For example if the carrier assigns 114.22.34.2 to the PPP connection this address will be made available to the CISCO 3200 ISR using DHCP and the address 114.22.34.1 will be assigned to the ECC

eth0 interface.

In this case DHCP responses will contain 114.22.34.1 as default gateway. Dynamic Bridge Mode is the default mode and must be used when the IP address assigned by the wireless

provider is not fixed but can change from one connection to another. An example of a Dynamic Bridge Mode configuration follows:

! Version 0.1 ! hostname myhost-hsdpa ! interface eth0 no IP address enable ! interface hsdpa0 IP address negotiated apn myhost pppbridge eth0 dynamic enable !

Note that, with this configuration, the eth0 interface can’t have an IP address assigned. The CISCO 3200 ISR must be configured accordingly as in the example below:

! interface FastEthernet0/0 ip address 10.200.1.24 255.255.0.0 duplex auto speed auto !

..........

! interface FastEthernet1/3 ! interface Vlan1 ip address dhcp ! !

Note that in this case the IP address of vlan1 interface is dynamically assigned by the DHCP server.

Static Bridge Mode

Static Bridge Mode should be used when the carrier-assigned public IP address is fixed. In this case, there is no need to use the DHCP-protocol, while the fixed address can be directly configured to the CISCO 3200 ISR Ethernet interface and the IP address assigned to the

eth0 interface of the HSDPA controller must be

chosen and configured by the user. This address must also be defined as default gateway on the CISCO 3200 ISR.

Forcing the cellular network to use

By default the hsdpa0 interface automatically uses the 2G (GSM) or 3G (WCDMA) network depending on the quality of the signal.

You can force the device to use only 2G or only 3G networks using the

mode command.

HSDPA interface information

The current status of the HSDPA interface can be retrieved using the show interface hsdpa0 command in User Mode:

HSDPA-rt# show interface hsdpa0 Interface hsdpa0 is Enabled physical status is PPP up Hardware type is HSDPA modem Network in use : HSDPA Cat. 6 (3.6Mbps) IP address is 91.80.172.179 255.255.255.255 link gateway is not set MTU 0 bytes qdisc is

From the output of this command the user will known: the interface status (enabled or disabled), the PPP link status (up or down), the IP address provided by the ISP and the type of network in use (GPRS if 2G or UMTS, EDGE or HSDPA for 3G networks).

Cellular network information

You can get detailed information about the current status and availability of the cellular network for the

hsdpa0 interface issuing the command show modem status in User Mode.

From the output of this command the user can know almost everything about the status of network registration.

Here is an example of the output of this command in a good 3G coverage area:

HSDPA-rt# show modem status Current status for modem interface hsdpa0 Current Time: 131566 Temperature: 50 Bootup Time: 57997 Mode: ONLINE System mode: WCDMA PS state: Attached WCDMA band: IMT2000 GSM band: Unknown WCDMA channel: 10564 GSM channel: 65535 GMM (PS) state:REGISTERED NORMAL SERVICE MM (CS) state: IDLE NORMAL SERVICE

WCDMA L1 State:L1M_DCH RRC State: CELL_DCH RX level (dBm):-70

This is the output of the show modem status command in an area with no 3G coverage:

HSDPA-rt# show modem status Current status for modem interface hsdpa0 Current Time: 8904 Temperature: 47 Bootup Time: 2 Mode: ONLINE System mode: WCDMA PS state: Attached WCDMA band: IMT2000 GSM band: GSM900 WCDMA channel: 10638 GSM channel: 65535 GMM (PS) state:REGISTERED LIMITED SERVICE MM (CS) state: IDLE LIMITED SERVICE

WCDMA L1 State:L1M_PCH_SLEEP RRC State: DISCONNECTED RX level (dBm):-104

Note the LIMITED SERVICE values for GMM and MM fields and the DISCONNECTED RCC state.

Page 24

DuraMAR 2150 – User’s Manual

The relevant fields in the output of this command are:

Temperature The internal temperature of the ECC HSDPA module

System mode GPRS (2G) or WCDMA (3G)

GMM and MM state NORMAL SERVICE or LIMITED SERVICE

RCC_STATE The registration status, CELL_DCH, CELL_FACH, DISCONNECTED (for 3G networks only)

RX level The quality of the signal received by the module

SNMP configuration

The system can be monitored using the SNMP protocol. Only SNMP version 2c is supported. The available information includes:

• the current 3G network type used by the

hsdpa0 interface

• the signal quality on the

hsdpa0 interface

• the internal temperature of HSDPA modem

• the internal temperature of CPU

SNMP traps are sent to the configured manager host if the temperatures of the HSDPA module or the CPU exceed a predefined fixed value and whenever there is a change on the 3G network type.

The basic configuration of the SNMP agent requires only the definition of a community name and the enabling of the service. Here are the required steps:

1. configure

2. snmp-server community private

3. snmp-server enable

4. exit

The complete list of commands available for the SNMP agent configuration is listed below:

snmp-server community

string

Sets the community name (this is a mandatory step)

Sets the contact name

snmp-server contact

string

Sets the locations of the device

snmp-server location

string

Sets the logical name of the device

snmp-server name

string

Sets the IP address of the management station

snmp-server host

ip-address

Enables the SNMP agent service

snmp-server enable

You can view the SNMP server status and configuration issuing the

show snmp-server command.

System administration

Changing 'admin' user password

The user can change the password that is used to protect the

admin

user logon.

While in Configuration Mode, the

passwd command is used to perform the change. The user will be asked for

the new password to be assigned to the admin user. The password is not echoed on the screen for security reasons. Moreover, the

passwd command is not shown in either running or start-up configuration files.

Page 25

DuraMAR 2150 – User’s Manual

Limiting remote access to the system

Access to the system by connecting through the gprs0 interface can be restricted to a list of specific IP addresses. There are no limits to the number of IP addresses in the list.

By default there is no access restriction. By issuing one or more

set admin-ip

ip-address

commands the

user can restrict the access to only the given IP addresses. The no-form of the command removes the permission. If the list is empty, the access will be automatically

granted from any IP address. Here is an example that allows access from just two IP address:

! set admin-ip 217.22.11.23 set admin-ip 217.22.11.24 !

These restrictions apply to any kind of IP traffic coming from an IP address that is not included in the list, thus also SSH, SNMP and ICMP packets will be rejected.

Rebooting the system

An immediate reboot of the ECC system can be performed by issuing the reboot command. Please note that this command will reboot ECC only, while CISCO 3200 ISR subsystem will not be affected.

Setting controller time and date

The user can setup the controller time and date using the set time configuration command. There is no internal battery for maintaining the system’s clock so, if the device is powered off for a couple of

hours or more, the time will be lost. If you need or want to maintain a precise system time you can keep the system clock in sync with up to three

external NTP (Network Time Protocol) servers using the

set ntp configuration command. Please note that

when the system operates in Bridge Mode, one or more static routes need to be defined for this feature to work (see further for details)

The complete list of commands available for managing system time:

show time

Displays the current time and date

Sets the current time and date values

set time hh:mm[:ss] mm/dd/yyyy

Defines up to three NTP servers

set ntp <ip-address> [ip-address ip address]

Setting the time zone

The internal clock is typically maintained in UTC coordinates. You can define the time zone in which the system is used using the set tz configuration command.

The time zone is expressed defining the name of a geographical area (ie. Europe, Asia,..) followed by the name of a city in that area (ie. Rome, Singapore,…). A question mark (?) can be used in place of the zone or city names, to obtain a list of these fields.

The syntax of this command is:

set tz <area name> <city name>

Page 26

DuraMAR 2150 – User’s Manual

Log files

Important events are logged on the flash memory. User can view the logged messages using the show log system command. Because the size of the flash memory available for the log file is limited, the size of the log file is checked periodically and, if it increases to more than 3MB, it is automatically resized to the last 1000 messages. At any moment user can clear the log file using the

delete log configuration command.

Log messages can also be saved on a remote syslog server using the

set log command. Please note that

when the system operates in Bridge Mode, one or more static routes need to be defined for this feature to work (see further for details).

The complete list of commands available for managing log files:

show log

Displays the contents of the log file

Removes all of the log messages

clear log

Defines the IP address of a remote syslog server

set log <ip-address>

Setting up static routes to access external resources

In order to access an external resource (such as a NTP or syslog server) when the system operates in Bridge Mode, the user must define one or more static routes through the gprs0 interface. This is required because in Bridge Mode the system can only forward traffic to the default route (the hsdpa0 interface). The syntax is:

route

ip-address netmask

dev gprs0

where ip-address and netmask are, respectively, the IP address and network mask of the external resource destination.

Upgrading the system

ECC firmware can be upgraded using the upgradefrom command. This command will download a new system image from a specific URL and automatically install it. For example:

HSDPA-r(config)# upgradefrom http://212.12.54.21/hymar-1.1.eff

An updated version of the controller firmware can be easily downloaded and installed from a remote HTTP or FTP server.

The upgrade process is a three-step procedure:

• the image file is downloaded alongside with some information that checks its integrity (an MD5 digest contained in a plain text file)

• the image file is processed for integrity check comparing the MD5 digests

• the new valid image is saved on the flash memory and the default start-up configuration file is updated

accordingly

The

upgradefrom configuration command performs all of these steps automatically. The syntax is the

following:

upgradefrom <URL-address>

At the end of the upgrade process the system must be rebooted without issuing the copy running command. This is important because the upgrade procedure updates the content of the startup configuration but not the content of the running configuration. Issuing the

copy running command will overwrite the

correct configuration.

Page 27

DuraMAR 2150 – User’s Manual

If needed the upgrade process can be performed manually with the following steps. First the new firmware image must be downloaded, verified and saved to the flash memory. This can be

done using the

download image command. This command will download the new image, check it’s

correctness and save it to the flash memory. The syntax is the following:

download image <URL-address>

Then the user should configure the system so that it will boot the new image at next reboot, using the

boot

system

configuration command. The syntax is the following:

boot system <image file name>

This command changes only the running configuration so, in this case, the user must issue the copy

running command before rebooting the system.

The

boot system command can be used at any time for selecting one of the firmware images available on

the flash disk as the system boot image. The list of images saved on the flash can be obtained using the

show boot-images command, while old images can be removed using the delete boot-image

configuration command. This command can be used to free space on the flash memory thus providing room for new images. The image installed by the manufacturer can’t be removed and is reported as default image and it will be used if

boot system command is removed from the configuration file.

The complete list of commands available for managing the system image files is listed below:

upgradefrom <URL-address>

Downloads and installs a new system image. At the end the system must be rebooted without issuing a copy running command

Downloads and saves on the flash memory a new system image file.

download image <URL-address>

Defines the image file to boot from. This is a configuration command so user must save the running configuration for saving the changes.

boot system <image-file>

Displays a list of the system image files currently on the flash memory,

show boot-images

Removes from the flash memory the specified system image file.

delete boot-image <image-file>

URL address format

The address where a new system image can be downloaded is defined using a standard URL (Uniform Resource Locator) address:

protocol://[username:password@]ip-address/file_name.eff

The protocols supported are HTTP and FTP, the remote server must be referred to using its IP address instead of its name because the system is not capable of resolving DNS names.

System upgrade can also be performed via remote SSH connection. From a remote system issue the command:

ssh admin@controller_IP updatefrom url

Installing a new firmware using the DuraMAR USB-disk key

Whenever the system doesn't boot as expected (for example in case some system file has become corrupted or unreadable) or whenever a new fresh installation is required, the user can install the firmware by using the provided USB-disk key. This operation is not intended be performed as routine maintenance but only in case of serious problems.

The DuraMAR USB-disk key contains maintenance software that performs a series of operations, including setting up the system storage memory layout and installing the firmware image contained in the USB-disk key itself. The status of the process can be monitored through the serial console. This process erases all

the data already present on the ECC and sets-up the system with factory defaults.

The procedure for installing a new firmware image is as follows:

1. Connect the serial console available under the service panel.

2. Connect the USB adaptor cable to the mini USB port available under the service panel.

3. Connect the DuraMAR USB-disk key with the adaptor cable.

4. Reboot or switch-on the system.

5. The system will boot from the USB-disk key. While the boot loader is loading the maintenance software, the light on the top of the USB-disk key flashes.

6. When the boot loader has finished loading the maintenance software, the light stops flashing and the boot process begins. From this moment the system activity will be reported with messages on the serial console.

7. At the end of the boot process the maintenance software performs the storage memory partitioning and firmware installation.

8. The installation procedure successfully terminates when the “OK” message appears on the console, otherwise a “KO” message notifies a failure.

9. Disconnect the USB-disk key and restart the system.

In case the installation process fails, the user must repeat the entire procedure.

DuraMAR 2150 – User’s Manual

Using the integrated CISCO router for hosting controller system image files.

Downloading a new image might be quite difficult if the ECC is configured to operate in Bridge Mode. In this configuration the HSDPA interface can’t be used by the ECC itself so users, setting the appropriate static routes, must download the new image from a remote host through the slow GPRS interface or from a local host connected to the CISCO Ethernet interface. The latter option is not a viable solution in Dynamic Bridge Mode configuration.

Under these circumstances it might be useful, at first, to download the image file on the flash memory of the CISCO router, that can use the HSDPA interface, and then, make this file available through the IOS integrated HTTP server.

The steps to perform on the CISCO router are:

• Copy from a remote server the image file (.eff) and its MD5 cecksum file (.md5). The IOS

copy

command

can copy a file from a remote host using different protocols like HTTP, FTP, TFTP, SSH and

RSH.

• Configure and enabl e the embedded HTTP server:

ip http authentication local ip http path flash: ip http server

• Define a local user with privilege access 15

user upgrade secret upgrade user upgrade privilege 15

At this point you can install the new system image issuing, on the controller, the upgradefrom command. For example:

upgradefrom http://upgrade:upgrade@ip-address/duramar2150-1.0.1.eff

DuraMAR-2150 service interface

A GPRS modem is included as part of the DuraMAR-2150 system in order to provide a diagnostics and backup/emergency connection to the system in the event that the HSDPA link fails.

This GPRS modem has a serial interface and can be connected through a software-controlled switch either to the

AUX interface of the CISCO 3200 ISR or to the ttyS1 interface of ECC using a software command or

an SMS command message. The

gprs0 interface is a 2G cellular interface that is mainly targeted for maintenance activity.

This is a special interface because it can be disconnected from the ECC and connected to the

AUX port of the

CISCO 3200 ISR using a software command. While connected to the ECC, its configuration is similar to the configuration of the

hsdpa0 interface.

While connected with the ECC the GPRS modem is accessible as

gprs0 interface and allows you to

establish a PPP connection and to access the device through the Internet. If switched to the CISCO 3200 ISR, the GPRS modem is accessible and configurable using standard IOS®

commands as a modem device connected to the

AUX router port.

You can define the device that the GPRS modem is connected with using the command:

set gprs cisco | controller

The change is immediate; if you want this setup to be permanent, you must save the running configuration issuing the

copy running command.

The GPRS modem is connected to a dedicated microcontroller that can force a system hardware reset. The reset functions can be asserted in response to a specific SMS command message.

In order for the message to be accepted by the system, it must be sent from a number that is contained in the internal SIM phonebook, messages that are received from unknown numbers are removed from the received message buffer.

Page 31

DuraMAR 2150 – User’s Manual

The commands are represented by the text of the SMS message. Available commands:

SERCPU

Connects the GPRS modem serial interface to ECC ttyS1 interface

Connects the GPRS modem serial interface to the AUX port of the CISCO 3200 ISR

SERCISCO

Force a hardware reset of ECC.

RESETCPU

Force a complete system reset with power-off/power-on cycling.

RESETALL

When a new SMS message is received, the subscriber number is checked against the available entries in the phonebook and the command is executed only if the number is verified.

Phonebook entries can be managed from ECC CLI using the

set phone-book command.

The complete syntax of the command is:

set phone-book <item> <number>

item

identifies the entry and must be a number between 1 and 4

number

is the authorized subscriber number and must include the international prefix (es. +39)

An item can be removed from the phonebook using the no-form of the command. For example the following command will remove the item at position 2:

no set phone-book 2

In order for the changes to be written to the GPRS modem you must issue a copy running command, otherwise any change will be lost after a system restart.

During the execution of this command, the gprs0 interface must be disabled, otherwise the modem phonebook can't be updated because the interface is in use by the ECC controller.

In case you are using a startup configuration with gprs0 interface enabled you must:

1. disable the gprs0 interface first

2. apply changes to the phone-book entries

3. save the running configuration using the copy running command

4. enable the gprs0 interface

5. issue a copy running command again

In this case there is no need for accessing the GPRS serial interface during the execution of the copy running command because the phone-book is unchanged.

Since the phone-book is loaded from the modem only when system is powered-on, after any change to the phone-book entries the system must be switched off and then switched on again in order for the changes to take effect.

Note:

Wait for about 30 seconds before switching on again
