Introduction
The Cisco ONS 15540 ESP and Cisco ONS 15540 ESPx are optical transport platforms that employ DWDM (dense wavelength division multiplexing) technology. With the Cisco ONS 15540 ESP and Cisco ONS 15540 ESPx, users can take advantage of the availability of dark fiber to build a common infrastructure that supports data, SANs (storage area networks), and TDM (time-division multiplexing) traffic.
Determining the Release of Your 2.5-Gbps transponder Module Functional Image
This section describes the process you use to determine the existing functional image version installed on your 2.5-Gbps transponder module.
To display the functional image version in a 2.5-Gbps transponder module, use the following command in privileged EXEC mode:
Example
The following example shows the functional image information for the 2.5-Gbps transponder module in slot 2/3:

Caveat Symptoms and Workarounds
This section describes the caveats for this release of the 2.5-Gbps transponder module functional image.
Symptom: Propagation of Loss-of-Light is faulty for IBM Sysplex ETR (external timer reference). Although the ETR link might come up and appear to work normally, protection switching operations of the ETR might be affected. This only affects multimode and extended range transponder modules.
Workaround: Upgrade the transponder module functional image to version 1.A3 or later.
Symptom: Some OC-48/STM-16 SFP transceivers in a y-cable APS configuration with extended range transponder modules, experience a Tx fault from the SFP optics that keeps the client laser from being turned on during y-cable APS operations. In some cases a delay in the client laser being turned on causes a failover traffic outage of several seconds.This only affects extended range transponder modules.
Workaround: Upgrade the transponder module functional image to version 1.A3 or later.
Symptom: An 8b10b encoded data stream at a 2.125-Gbps encoded rate (2-Gbps Fibre Channel, 2-Gbps FICON, 2-Gbps ISC or similar protocol) exhibits intermittent or dribbling bit errors on the Type 2 extended range transponder module. The bit errors are data-traffic-dependent; that is, the rate at which they occur decreases with increasing link utilization, usually disappearing completely at high utilization. Other higher and lower rates such as OC-48/STM-16 and Gigabit Ethernet do not exhibit this problem on the same transponder link.This only affects extended range transponder modules, up to and including hardware version 5.1.
Workaround: Upgrade the transponder module functional image to version 1.A3 or later. The functional image must be upgraded on all transponder modules in the failing 2-Gbps FC/FICON/ISC link.
Symptom: If a local transparent interface is encapsulated for 2-Gbps Fibre Channel or FICON and monitoring is disabled, a Loss of Light condition results in the far-end wave interface remaining up with a Loss of Sync condition.
Workaround: Enable monitoring on the transparent interface.
Limitations and Restrictions
This section provides limitations and restrictions for Cisco ONS 15540 ESP and Cisco ONS 15540 ESPx hardware and software.
2.5-Gbps Transponder Module
The 2.125-Gbps rate protocols (2-Gbps Fibre Channel, 2-Gbps FICON, and 2-Gbps ISC) on 2.5-Gbps transponder modules with a functional image version of 1.A2 or later at one end of the DWDM have incompatible data formats with lower functional image versions at the other end. This only affects single-mode and extended range transponder modules.

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
