The Cisco ONS 15540 ESPx is an optical transport platform that employs DWDM (dense wavelength division multiplexing) technology. With the 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. The system uses an enhanced chassis with front fiber-optic cable access for optical interconnections between transponders and optical mux/demux modules. For more information about DWDM technology and applications, refer to theIntroduction to DWDM Technologypublication and the Cisco ONS 15540 ESPx Planning and Design Guide .

Determining the Software Version
Note We strongly recommend that you use the latest available software release for all Cisco ONS 15540 ESPx
hardware.
To determine the version of Cisco IOS software currently running on a Cisco ONS 15540 ESPx system, log in to the system and enter the show version EXEC command.
Note Always set the configuration register to 0x2102 when upgrading the system image using the
config-reg 0x2102 command in configuration mode.
Caution Improper system image upgrades can affect system functioning and redundancy. Always follow the recommended upgrade procedures.
Feature Set Table
The Cisco IOS Release software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. Table 2 lists the Cisco IOS software feature sets available for the Cisco ONS 15540 ESPx.
Table 2 Feature Sets Supported by the Cisco ONS 15540 ESPx
This section lists the caveats and corrected caveats for each release. Use Table 3 to determine the status of a particular caveat. In the tables, "C" indicates a corrected caveat, and "O" indicates an open caveat.
Table 3 Caveat Matrix for the Cisco ONS 15540 ESPx
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: The SRC reprogram for the standby processor card fails.
Workaround: Run the SRC reprogram on the active processor card, enable the processor switchover after switchover, and then run the SRC reprogram on the new active processor card. Remove and reinsert the processor card for the new FPGA to become effective.
Symptom: Loss of signal might occur before SD (signal degrade) and SF (signal failure) thresholds are exceeded and traffic may still continue to pass transparently.
The loss of signal detection is taken from the OE (optical to electrical) conversion subsystem which is different from the source of the SD and SF counters. The loss of light sensitivity is a characteristic of the OE conversion unit and it may vary from unit to unit but is always < -30dBm.
Symptom: When the Rx port fiber is removed from the transponder module, ingress alarms are reported and cleared repeatedly. The alarm should not clear and the alarm should be reported only once.
Symptom: Processor card gets into a nonresponsive state for an extended interval, during which time the active/standby LEDs may not indicate the correct active/standby state.
Workaround: If the processor card has not been reset by the redundant processor card, the non-responsive processor card can be removed and re-inserted in the chassis. This may cause a brief hit to data traffic, but the redundant processor card should take over and bring the system back up.
Symptom: The encapsulation fastethernet command fails on multimode transponders. The clock rate 100000 command succeeds but then pings over the signal fail intermittently.
Symptom: Client transmit enabled upon insertion disrupts y-cable clients.
Workaround: Remove client transmit fiber (y-cable leg) from the standby transponder before reinserting. Connect it back a few seconds after re-insertion of the standby transponder.
Symptom: The first time you OIR the OSC linecard, the card is brought admindown state.
Workaround: Enter the no shutdown command when the interface recovers.
Limitations and Restrictions
This section contains limitations and restrictions that apply to the Cisco ONS 15540 ESPx.
Transponder Modules
This section contains limitations and restrictions that apply to transponder modules.
When you insert the standby transponder module in a y-cable protected configuration, remove the cable from the transponder module before inserting the transponder module into the shelf. Failure to remove the cable might result in errors that can affect the performance of the active signal received by the client equipment.
CRC errors may occur with 2-Gbps Fibre Channel on single-mode transponders when high input power levels are received from the client laser sources.
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.
If both processor cards are removed, traffic through the system is affected as follows:
For Type 2 extended range transponder modules, traffic is shut down.
For 10-GE transponder modules, traffic is shut down.
Type 1 SM transponder modules and MM transponder modules do not operate reliably. The traffic might be affected.
In the shutdown state, the Status LED on the line card motherboard turns orange.
Note Traffic on pass through optical channels (which passively pass through the mux/demux
modules) are not affected by the removal of the processor cards.
