Chapter 4, Provisioning

This chapter discusses the provisioning procedures for the Cisco ONS 15216 EDFA2.

The login process is required to establish a communication session with the ONS 15216 EDFA2. To complete the provisioning process, this communication session is mandatory.

Step 2

Open HyperTerminal. (HyperTerminal can be found in the Microsoft Windows Accessories menu.)

Step 4

If the user name or password is not correct, the user is returned to the user name prompt. Example 4-2 displays the login response.

Set the IP Address Procedure

For connection of the ONS 15216 EDFA2 to a LAN, it is mandatory to set the ONS 15216 IP address. After the login step is completed, setting of the IP address is initially accomplished through a local serial communication interface (CLI) using the RS-232 port on the front of the module and a PC serial COM port.

Step 1

Use the snmp row set local cerent15216EdfaSromIpMgmtGroup command to set the IP address, subnet mask, gateway address, and host name. If you do not have an IP address, subnet mask, gateway address, or host name, contact your network administrator.

Step 2

At the command prompt, enter the snmp row set local cerent15216EdfaSromIpMgmtGroup command (displayed in Example 4-3) and press Enter.

Because row set is being used in this command, the user is prompted row by row to enter the IP address, the subnet mask, the gateway address, and the community ID (host name).

You have now assigned the IP address to the ONS 15216 EDFA. You must save these changes prior to terminating the session. You must also reboot the system to make the IP address active. Use the processor reset command. (See the "processor reset Command" section on page 6-8.)

Connect Through a Telnet Session Procedure (Optional)

Provisioning of the ONS 15216 EDFA2 can be accomplished entirely through the RS-232 port using CLI or SNMP commands. After an IP address is assigned, it is easier to provision the ONS 15216 EDFA2 using Telnet or an SNMP manager. A Telnet client is needed for CLI commands over IP. A generic SNMP manager is required for SNMP management over IP. After connecting the ONS 15216 EDFA2 to the network through its RJ-45 port, the user can configure the module to accept SNMP and CLI commands via Telnet using the following procedure:

Note To perform this procedure, the ONS 15216 EDFA2 must be connected to the network via the RJ-45 port.

Set Power Bus Mode (Simplex or Duplex)

The ONS 15216 EDFA2 allows users to set a simplex (one power source-Bus A) or duplex (redundant power source-Bus A and Bus B) power bus mode. Use the snmp attribute set local cerent15216EdfaPowerBusMode command to set the desired power bus mode. The default mode is duplex. See Example 4-4.

Verify Amplifier Operational Status

To ensure that the amplifier is working correctly on the optical level, you must verify the amplifier operational status. Use the snmp table display local cerent15216EdfaOverallStatusGroup command to verify amplifier operational status. Example 4-5 displays the output of this command.

The input power should be consistent with the input power measured during the optical connection procedure. See the "Optical Connection Procedure" section on page 3-6 for more information. The output power value should be 22 dB greater than the input, assuming that the default gain setting is 22 dB.

Note An input power higher than -5 dBm will return a Gain Out of Range alarm that can be cleared by correctly setting the gain value. For more information, refer to Table 2-2.

Set Gain

To ensure that the ONS 15216 EDFA2 output signal is received by the transceiver in the network element, it is important that the gain is set correctly.

The desired output power per channel is dependent on the number of channels traversed in the amplifier. The user sets the gain of the amplifier depending on the input power level, the network application, and the required receiver specifications necessary for error-free operation. Gain range is provided in Table 3-3.

To set the amplifier gain, enter the snmp attribute set local cerent15216EdfaConstGainOverallGain {<gain #>}, where <gain #> is the gain value multiplied by ten. For example, if the gain value is 20 dB, the gain # would be set to 200.

Note Prior to changing or implementing gain changes, consult with a Cisco Systems Engineer to ensure proper network operation.

Set Alarm Thresholds

Alarm thresholds are set so that the network operator can be notified when valid alarms occur via the RJ-45 ALARM OUT and RJ-45 LAN ports on the front panel of the ONS 15216 EDFA2. (See Figure 4-1.)

Alarms can be connected to a NOC NMS via a network element miscellaneous discrete input and/or office alarm panel/system.

For a full description of alarm threshold command attributes, refer to Chapter 6 SNMP commands.

To display the alarm thresholds, use the snmp table display local cerent 15216EdfaCfgGroup command ( Example 4-6). This command returns the current alarm threshold default values.

To set the alarm thresholds, use the snmp row set local cerent15216EdfaCfgGroup command. After this command is entered, the user is prompted to modify each attribute, row by row, until all attributes are set. Alarm threshold attributes are described in Table 4-1.

Table 4-1 Alarm Threshold Attribute Definitions
Attribute	Variable Definition	Syntax	Maximum Access	Description
cerent15216EdfaCfgSaved	Configuration Saved Status	True Value	Read-only	Indicates whether the current configuration has been saved. The value can be true or false. If false, the configuration is not saved.
cerent15216EdfaLpoutSetpoint	Loss of Output Power Setpoint	Integer (0 to 1000)	Read-only	Can be disregarded when operating amplifier in factory default, constant gain mode. Setpoint object is only valid when amplifier is used in constant output power modes of operation.
cerent15216EdfaLpoutDeviation	Loss of Power Output Deviation	Integer (0 to 1000)	Read-write	Can be disregarded when operating amplifier in factory default, constant gain mode. Deviation object is only valid when amplifier is used in constant output power modes of operation.
cerent15216EdfaLpoutHysteresis	Loss of Power Output Hysteresis	Integer (0 to 1000)	Read-write	Can be disregarded when operating amplifier in factory default, constant gain mode. Hysteresis object is only valid when amplifier is used in constant output power modes of operation.
cerent15216EdfaLOSThreshold	Loss of Input Signal Threshold	Integer (-3100 to -1500)	Read-write	Notifies operations personnel if the optical input signal of the ONS 15216 EDFA2 drops below a level that impacts proper operation of optical network. Set this attribute at a value that is appropriate for the intended application so that the alarm condition is meaningful. Consult with a Cisco Systems Engineer to determine the threshold value for your application. As a guideline, Cisco recommends setting the threshold value at 3 dBm below the current input power level of the amplifier. Valid entries are between -3100 and -1500 dBm times 100. For example, if the total input power of the amplifier is -24 dBm and the loss of input power threshold required is -27 dBm, the loss of input power alarm threshold is -2700.
cerent15216EdfaLOSHysteresis	Loss of Input Signal Hysteresis	Integer (0 to 1000)	Read-write	Used to set the amount the input signal must increase above the LOS Threshold level before the alarm is cleared. This attribute, in conjunction with the loss of input signal alarm threshold, enables efficient clearing of alarms. Set this attribute at a value that is appropriate for the application so that the alarm condition will clear when input is stable. Consult with Cisco Systems Engineer to determine the correct value for your application. As a guideline, Cisco recommends setting the value 1 dBm above the LOS Threshold value. With this setting, the module will clear the alarm if it detects a signal level of 1 dBm above the current LOS Threshold value. Valid entries are between 0 and 1000 and are in dBm times 100. For example, if the hysteresis required is 1 dBm, the power alarm hysteresis is 100.
cerent15216EdfaCtmpMin	Case temperature minimum	Integer (-10 to 10)	Read-write	Notifies operations personnel notification if the case temperature of the ONS 15216 EDFA2 drops below a level that impacts proper operation of the optical network. The minimum case temperature should be set at a value that is appropriate for the intended application and within product specifications. Users should consult with a Cisco Systems Engineer to determine the threshold value for their application. As a guideline, Cisco recommends that minimum case temperature be set at 1�C. Valid entries are between -10 and 10�C.
cerent15216EdfaPowerBusDCVoltageMin	Power bus voltage minimum	Integer (0 to 70)	Read-write	Minimum allowable power bus DC voltage. The default minimum power bus voltage is set at -40 VDC. Valid entries are between 0 and 70 and are in volts times 10. For example, if the voltage required is -50 VDC, the power bus DC voltage is 500.
cerent15216EdfaPowerBusDCVoltageMax	Power bus voltage maximum	Integer (0 to 70)	Read-write	Maximum allowable power bus DC voltage. The default maximum power bus voltage is set at -57 VDC. For example, if the voltage required is -50 VDC, the power bus DC voltage is 500.
cerent15216EdfaCtmpMinHysteresis	Case Temperature Hysteresis	Integer (0 to 10)	Read-write	Used to set the amount the case temperature of the module must rise above the minimum case temperature alarm level before the alarm is cleared. This attribute, in conjunction with the case temperature minimum, enables efficient clearing of alarms. Set the hysteresis at a value that is appropriate for the application so that the alarm condition will clear when the input is stable. The user should consult with Cisco Systems Engineer in order to determine the value for their application. As a guideline, Cisco recommends that the hysteresis value be set at 1�C. Valid entries are between 0 and 10�C.
cerent15216EdfaCtmpMax		Integer (20 to 70)	Read-write	Notifies operations personnel if the case temperature of the ONS 15216 EDFA2 is at a level that may impact proper operation of the optical network. Set the maximum case temperature at a value that is appropriate for intended application and within product specifications. Consult with a Cisco Systems Engineer to determine the threshold value for your application. As a guideline, Cisco recommends that minimum case temperature value be set at 50�C. Valid entries are between 20 and 70�C.
cerent15216EdfaCtmpMaxHysteresis		Integer (0 to 10)	Read-write	Used to set the amount the case temperature of module must drop below the maximum case temperature alarm level before the alarm is cleared. This attribute, in conjunction with the case temperature minimum, enables efficient clearing of alarms. Set the hysteresis at a value that is appropriate for the application. If an alarm occurs, the case temperature must return to 1oC below the set value to clear the alarm. Consult with a Cisco Systems Engineer to determine the value for your application. As a guideline, Cisco recommends setting the value at 1�C. Valid entries are between 0 and 10�C. Setting this value to 0 disables this option.
cerent15216EdfaCLEI		Display String (0 to 10 characters)	Read-only	Indicates the factory setting of the Common Language Equipment Identifier (CLEI) code (established by Telcordia) of the Cisco ONS 15216 EDFA2. This attribute can be accessed, but it cannot be changed by the user.

Set Password

To restrict access to the ONS 15216 EDFA2, use the user passwd modify command to change the default user password. Example 4-7 displays the user passwd modify syntax. Enter the user passwd modify command followed by a space, the default password followed by a space, and the new password (as displayed in Example 4-7.

With the exception of the monitor level (read-only) user, the user can only modify the password for their assigned level. For additional information on user levels, refer to Table 3-5.
