Introduction
The Cisco ONS 15540 ESP is an optical transport platform that employs DWDM (dense wavelength division multiplexing) technology. With the Cisco ONS 15540 ESP, users can take advantage of the availability of dark fiber to build a common infrastructure that supports data, SAN (storage area networking), and TDM (time-division multiplexing) traffic. For more information about DWDM technology and applications, refer to the Introduction to DWDM Technology publication and the Cisco ONS 15540 ESP Planning and Design Guide.
System Requirements
This section describes the system requirements for Cisco IOS Release 12.1(11b)E, and it includes the following sections:
•
Memory Requirements
The DRAM memory configuration is 128 MB, which is the default for the Cisco ONS 15540 ESP.
Hardware Supported
Table 1 lists the hardware components supported on the Cisco ONS 15540 ESP and the minimum software version required. See the "Determining the Software Version" section for information on determining your software version.
Determining the Software Version
Note
To determine the version of Cisco IOS software currently running on a Cisco ONS 15540 ESP system, log in to the system and enter the show version EXEC command. The following sample output is from the show version command. The software version number is shown on the second line of the sample output.

This section describes the caveats in the Cisco ONS 15540 ESP.
Symptom: If you attempt to change or edit a threshold in the threshold list that is already associated with an interface, the threshold is applied to that interface even when no changes are made to it. Usually the change in error counts are more important than the error counters themselves.
Workaround: Issue the clear counters command.
Symptom: If CiscoView files are extracted on a Flash Disk (disk0: or disk1:), the package does not work.
Workaround: Install CiscoView on a Flash PC Card (slot0: or slot1:).
Symptom: When there is a constant stream of loss of sync alarms, a port fail notification is not generated. Although both signal failure and signal degrade thresholds are applied, only signal degrade is observed. The signal failure threshold is monitored by hardware registers. When the signal failure threshold is exceeded, the hardware normally generates a port fail notification. Because the loss of sync alarms are constant, the threshold exceeded cannot generate a port fail notification. The signal degrade is reported because it is monitored by software and does not need any notifications from hardware.
Workaround: Disable and reenable monitoring once with the no monitor/monitor enable command sequence to generate the port fail notification.
Symptom: Upon switchover, the active processor card can become nonresponsive. The processor card's Active LED will remain on, even though it is no longer actively controlling the system.
Workaround: None
Remove and reinsert the processor card to correct the fault.
Symptom: An error can occur with management protocol processing. Please use the following URL for further information:
http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903Workaround: None
Symptom: The following errors might occur:
–

–
–
Workaround: None.
Symptom: Loopback cannot be configured on the wave interface of a extended range transponder module if no transceiver is present. The loopback command is accepted but the loopback is not configured.
Workaround: Insert a transceiver before configuring the loopback on the wave interface.
Symptom: When laser safety control is enabled on the OSC wave 0 interface or wave 1 interface, the OSC trunk laser does not shut down when a fiber cut occurs.
Workaround: None
Limitations and Restrictions
This section contains limitations and restrictions that apply to the Cisco ONS 15540 ESP.
Transponder Modules
This section contains limitations and restrictions that apply to transponder modules.
•
•
Data errors or link-down conditions for 2-Gbps Fibre Channel might occur when used with certain client laser sources. Transmitters in some client GBIC and SFP transceiver units might send large overshoots in optical power with signal bit transitions, causing momentary overload conditions on the transponder client side receiver. The average transmitted power level from the GBIC does not violate the overload specification of the transponder client side receiver, so a power meter does not detect the overload.
The workaround is to attenuate the signal from the client equipment to a recommended level of -12 dBm when transmitting 2-Gbps Fibre Channel services.

•
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:
All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA).
