FC_MR-4 Operations

The FC_MR-4 is a 1.0625- or 2.125-Gbps Fibre Channel/Fiber Connectivity (FICON) card that integrates non-SDH framed protocols into an SDH time-division multiplexing (TDM) platform through virtually concatenated payloads. This chapter provides information about the FC_MR-4 card. For installation and step-by-step circuit configuration procedures, refer to the Cisco ONS 15454 SDH Procedure Guide.

FC_MR-4 Application

17.1  FC_MR-4 Card Description

Warning Class 1 (CDRH) and Class 1M (IEC) laser products.

Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure.

Warning High-performance devices on this card can get hot during operation. To remove the card, hold it by the faceplate and bottom edge. Allow the card to cool before touching any other part of it or before placing it in an antistatic bag.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.

The FC_MR-4 (Fibre Channel 4-port) card uses pluggable Gigabit Interface Converters (GBICs) to transport non-SONET/SDH-framed, block-coded protocols over SONET/SDH in virtually concatenated or contiguously concatenated payloads. The FC_MR-4 can transport Fibre Channel over SONET/SDH using Fibre-Channel client interfaces and allows transport of one of the following at a time:

Two contiguously concatenated (CCAT) STS-24c/VC4-8c circuits

One STS-48c/VC4-16c CCAT

Two virtually concatenated (VCAT) circuits (STC3c-8V/VC4-8v) compliant with ITU-T G.7041 GFP-T and Telcordia GR-253-CORE

One STS-24c/VC4-8c CCAT and one STS-24c/VC4-8c VCAT

In Software Release 4.6, only two of the four ports can be active at one time.

Figure 17-1 shows the FC_MR-4 faceplate and block diagram.

17.1.1  FC_MR-4 Card-Level Indicators

Table 17-1 describes the two card-level LEDs on the FC_MR-4 card.

Table 17-1 FC_MR-4 Card-Level Indicators  

Card-Level Indicators

The red FAIL LED indicates that the card's processor is not ready. The FAIL LED is on during reset and flashes during the boot process. Replace the card if the red FAIL LED persists.


If the ACT/STBY LED is green, the card is operational and ready to carry traffic.


If the ACT/STBY LED is amber, the card is rebooting.

17.1.2  FC_MR-4 Port-Level Indicators

Each FC_MR-4 port has a corresponding ACT/LNK LED. The ACT/LNK LED is solid green if the port is available to carry traffic, is provisioned as in-service, and in the active mode. The ACT/LNK LED is flashing green if the port is carrying traffic. The ACT/LNK LED is steady amber if the port is not enabled and the link is connected, or if the port is enabled and the link is connected but there is an SDH transport error. The ACT/LNK LED is unlit if there is no link.

You can find the status of the card ports using the LCD screen on the ONS 15454 SDH fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot. Refer to the Cisco ONS 15454 Troubleshooting Guide for a complete description of the alarm messages.

17.1.3  FC_MR-4 Compatibility

The FC_MR-4 cards can be installed in Slots 1 to 6 and 12 to 17 when used with XCVXL 2.5G, XCVXL 10G, and XC10G cards. The card can be provisioned as part of any valid ONS 15454 SDH network topology, such as a subnetwork connection protection ring (SNCP) (CCAT circuits only), multiplex section-shared protection ring (MS-SPRing), 1+1 subnetwork connection (SNC), unprotected, or linear network topologies.

17.1.4  FC_MR-4 Card Specifications

The FC_MR-4 card has the following specifications:


Operating temperature

C-Temp (15454-E100T): -5 to +55 degrees Celsius (23 to 131 degrees Fahrenheit)

For compliance information, refer to the Cisco Optical Transport Products Safety and Compliance Information.

17.2  FC_MR-4 Application

The FC_MR-4 reliably transports carrier-class, private-line Fibre Channel/FICON transport service. Each FC_MR-4 card can support up to two 1-Gbps circuits or a single 2-Gbps circuit. A 1-Gbps circuit is mapped to an STS-24c/VC4-8c (STS-3c-8v) and 2-Gbps circuits are mapped to an STS-48c/VC4-24c.

The FC_MR-4 card incorporates features optimized for carrier-class applications such as:

Carrier-class Fibre Channel/FICON

50 ms of switch time through SONET/SDH protection as specified in Telcordia GR-253CORE

Hitless software upgrades

Remote Fibre Channel/FICON circuit bandwidth upgrades via integrated Cisco Transport Controller (CTC)

Multiple management options through CTC, Cisco Transport Manager (CTM), TL1 (for SONET only), and Simple Network Management Protocol (SNMP)

The FC_MR-4 payloads can be transported over the following protected circuit types, in addition to unprotected circuits:

SNCP (CCAT circuits only)



Protection channel access (PCA)

The FC_MR-4 card supports high-order virtual concatenation (VCAT). See the "10.14  Virtual Concatenated Circuits" section on page 10-22.

The FC_MR-4 uses pluggable GBICs for client interfaces and is compatible with the following GBIC types:

ONS-GX-2FC-SML= (2Gb FC 1310nm Single mode with SC connectors)

ONS-GX-2FC-MMI= (2Gb FC 850nm Multi mode with SC connectors)
