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 network), 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(7a)EY2, and includes the following sections:
•
Memory Requirements
The DRAM memory configuration is 128MB, 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.

Caveats
This section describes the caveats in the Cisco ONS 15540 ESP.
•
Symptom: Sysplex Timer protocol encapsulation does not function correctly if APS protection is configured on the interface with unidirectional path switching.
Workaround: Configure bidirectional path switching on interfaces that have Sysplex Timer protocol encapsulation and APS protection.
•
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.
Workaround: None.
•
Symptom: If CiscoView files are extracted to the SanDisk (disk0 and disk1), the package does not work.
Workaround: Install CiscoView on other PCMCIA cards (slot0 and slot1).
•
Symptom: If you enter the show connect intermediate command while the transmit or receive trunk cable only is disconnected with bidirectional APS configured to work over OSCP, spurious memory access occurs and the following messages appear:
%ALIGN-3-SPURIOUS: Spurious memory access made at 0x601511F8 reading 0x2C 00:03:16: %ALIGN-3-TRACE: -Traceback= 601511F8 60152180 6037D0E4 6037D2E4 6037DF18 6005A064 60066ADC 600BFB0C 00:03:16: %ALIGN-3-TRACE: -Traceback= 601511F8 60152180 6037D0E4 6037D378 6037DF18 6005A064 60066ADC 600BFB0C
This is a timing problem that does not happen often. This does not impact any functionality and is a self-correcting situation.Workaround: None
•
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.
Limitations and Restrictions
This section provides limitations and restrictions for Cisco ONS 15540 ESP hardware and software.
Transponder Modules
This section contains limitiations and restrictions that apply to transponder modules.
•
•
Data errors or link-down conditions for 2-Gbps Fibre Channel might occur on single-mode transponders 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.
