Introduction

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 the Introduction to DWDM Technology publication and the Cisco ONS 15540 ESPx Planning and Design Guide.

This section describes the caveats in the Cisco ONS 15540 ESPx.

CSCdv90351 · ·

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.

CSCdx70683 · ·

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.

CSCdx07666 · ·

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.

Workaround: None.

CSCdx32438 · ·

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.

Workaround: None

CSCdx37144 · ·

Symptom: Processor card gets into a nonresponsive state.

Workaround: None

CSCdx42463 · ·

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.

CSCdx80804 · ·

Symptom: The encapsulation fastethernet command fails on multimode transponders. The clock rate 100000 command succeeds but then pings over the signal fail intermittently.

Workaround: None.

CSCdx80175 · ·

Symptom: The show interface command output for a wave interface displays an "up" state but the Signal Quality shows loss of sync.

Workaround: None.

CSCdx87061 · ·

Symptom: CiscoView might display a different receive LED status on transponders from what is actually seen on the device.

Workaround: None.

CSCdx89540 · ·

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.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

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:

http://www.cisco.com/tac

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:
