MXP_MR_2.5G and MXPP_MR_2.5G Card Description

The MXP_MR_2.5G card aggregates a mix and match of client Storage Area Network (SAN) service client inputs (GE, FICON, Fibre Channel, and ESCON) into one 2.5 Gbps STM-16/OC-48 DWDM signal on the trunk side. It provides one long-reach STM-16/OC-48 port per card and is compliant with Telcordia GR-253-CORE.


Note In Release 7.0, two additional operating modes have been made available to the user: pure ESCON (all 8 ports running ESCON), and mixed mode (port 1 running FC/GE/FICON, and ports 5 through 8 running ESCON). When the card is part of a system running Release 6.0 or earlier, only one operating mode, FC/GE, is available for use.


The MXPP_MR_2.5G (2.5-Gbps Multirate Muxponder-Protected-100 GHz-Tunable 15xx.xx-15yy.yy) card aggregates various client SAN service client inputs (GE, FICON, Fibre Channel, and ESCON) into one 2.5 Gbps STM-16/OC-48 DWDM signal on the trunk side. It provides two long-reach STM-16/OC-48 ports per card and is compliant with ITU-T G.957 and Telcordia GR-253-CORE.

Because the cards are tunable to one of four adjacent grid channels on a 100-GHz spacing, each card is available in eight versions, with 15xx.xx representing the first wavelength and 15yy.yy representing the last wavelength of the four available on the card. In total, 32 DWDM wavelengths are covered in accordance with the ITU-T 100-GHz grid standard, G.692, and Telcordia GR-2918-CORE, Issue 2. The card versions along with their corresponding wavelengths are shown in Table 1.

Signal Types

The client interface supports the following payload types:

2G FC

1G FC

2G FICON

1G FICON

GE

ESCON


Note Because the client payload cannot oversubscribe the trunk, a mix of client signals can be accepted, up to a maximum limit of 2.5 Gbps.


Data Rates

Table 2 sshows the input data rate for each client interface, and the encapsulation method. The current version of the ITU-T Transparent Generic Framing Procedure (GFP-T) G.7041 supports transparent mapping of 8B/10B block-coded protocols, including Gigabit Ethernet, Fibre Channel, and FICON.

In addition to the GFP mapping, 1-Gbps traffic on Port 1 or 2 of the high-speed serializer/deserializer (SERDES) is mapped to an STS-24c channel. If two 1-Gbps client signals are present at Port 1 and Port 2 of the SERDES, the Port 1 signal is mapped into the first STS-24c channel and the Port 2 signal into the second STS-24c channel. The two channels are then mapped into an OC-48 trunk channel.

Client and Trunk Ports

The MXP_MR_2.5G card features a 1550-nm laser for the trunk/line port and a 1310-nm or 850-nm laser for the client ports depending on the small form-factor pluggable (SFP) . The card contains SFP modules for the client interfaces. For optical termination, each SFP uses two LC connectors, which are labeled TX and RX on the faceplate. The trunk port is a dual-LC connector.

The MXPP_MR_2.5G card features a 1550-nm laser for the trunk/line port and a 1310-nm or 850-nm laser (depending on the SFP) for the client port. The card contains eight SFP modules for the client interfaces. For optical termination, each SFP uses two LC connectors, which are labeled TX and RX on the faceplate. There are two trunk port connectors (one for working and one for protect). Each is a dual-LC connector.

Card Protection

The MXP_MR_2.5G card supports Y-cable protection. Two MXP_MR_2.5G cards can be joined in a Y-cable protection group, which provides protection against failures on the fiber and in the muxponders.

The MXPP_MR_2.5G card supports splitter protection, which provides protection against failures due to fiber cuts or unacceptable signal degradation on the trunk side. See the Cisco ONS 15454 DWDM Reference Manual for more detailed information.


Note Protection switching occurs only if the protect line is error free.


Performance Monitoring

GFP-T performance monitoring (GFP-T PM) is available via remote monitoring (RMON), and trunk PM is managed according to Telcordia GR-253-CORE and ITU G.783/826. Client PM is achieved through RMON for FC and GE.

Distance Extension

A buffer-to-buffer credit management scheme provides FC flow control. With this feature enabled, a port indicates the number of frames that can be sent to it (its buffer credit), before the sender is required to stop transmitting and wait for the receipt of a "ready" indication The MXP_MR_2.5G and MXPP_MR_2.5 cards support FC credit-based flow control with a buffer-to-buffer credit extension of up to 1600 km (994.2 miles) for 1G FC and up to 800 km (497.1 miles) for 2G FC. The feature can be enabled or disabled.

Slot Compatibility

You can install MXP_MR_2.5G and MXPP_MR_2.5G cards in Slots 1 to 6 and 12 to 17. The cards cannot operate without a TCC2 or TCC2P card installed in the node. Cross-connect cards do not affect the operation of the muxponder cards.

Faceplates

Figure 1 shows the MXP_MR_2.5G and MXPP_MR_2.5G faceplates.

Figure 1 MXP_MR_2.5G and MXPP_MR_2.5G Faceplates

Block Diagram

Figure 2 shows a block diagram of the MXP_MR_2.5G card. The card has eight SFP client interfaces. Ports 1 and 2 can be used for GE, FC, FICON, or ESCON (ESCON is available for Software R7.0 and later). In Software R7.0 and later, Ports 3 through 8 are used for ESCON client interfaces. There are two SERDES blocks dedicated to the high-speed interfaces (GE, FC, FICON, and ESCON) and two SERDES blocks for the ESCON interfaces. A FPGA is provided to support different configurations for different modes of operation. This FPGA has a Universal Test and Operations Physical Interface for ATM (UTOPIA) interface.

The MXPP_MR_2.5G is the same, except a 50/50 splitter divides the power at the trunk interface. In the receive direction, there are two APDs, two SERDES blocks, and two TADM framers. This is necessary to monitor both the working and protect paths. A switch selects one of the two paths to connect to the client interface.

Figure 2 MXP_MR_2.5G and MXPP_MR_2.5G Block Diagram

Automatic Laser Shutdown

Automatic laser shutdown (ALS) is a safety mechanism used in the event of a fiber cut.The ALS procedure is supported on both client and trunk interfaces. On the client interface, ALS is compliant with ITU-T G.664 (6/99). On the data application and trunk interface, the switch on and off pulse duration is greater than 60 seconds. The on and off pulse duration is user-configurable. For details regarding ALS provisioning for the MXP_MR_2.5G and MXPP_MR_2.5G cards, see the Cisco ONS 15454 DWDM Procedure Guide.

Card-Level Indicators

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 272



Note If protective clips are installed on the card connectors, remove the clips before installing the cards.



Note If you install a card incorrectly, the FAIL LED flashes continuously.


Figure 3 shows general card installation.

Figure 3 Installing a Card in the Cisco ONS 15454 (ANSI) Shelf Assembly


Step 1 Display the card installation plan for the node using one of the following sources:

The Cisco MetroPlanner Site Dialog window for the node you are provisioning.

CTC node view with slots preprovisioned based on the Cisco MetroPlanner Site Dialog window.

Written slot plan. The plan must be based on the Cisco MetroPlanner Site Dialog window for your installation.

Step 2 Remove the card from its packaging, then remove the protective clips from the backplane connectors.

Step 3 Open the card latches/ejectors.

Step 4 Use the latches/ejectors to firmly slide the card along the guide rails until the card plugs into the receptacle at the back of the slot.

Step 5 Verify that the card is inserted correctly and close the latches/ejectors on the card.


Note It is possible to close the latches and ejectors when the card is not completely plugged into the chassis. Ensure that you cannot insert the card any further.


Step 6 Verify the LED activity:

The red FAIL LED turns on for 20 to 30 seconds.

The red FAIL LED blinks for 35 to 45 seconds.

All LEDs blink once and turn off for 5 to 10 seconds.

The ACT or ACT/STBY LED turns on. The SF LED can persist until all card ports connect to their far-end counterparts and a signal is present.

Step 7 If the card does not boot up properly, or the LED activity does not occur as described in Step 6, check the following:

When a physical card type does not match the type of card provisioned for that slot in CTC, the card might not boot. If a card does not boot, open CTC and ensure that the slot is not provisioned for a different card type before assuming that the card is faulty.

If the red FAIL LED does not turn on, check the power.

If you insert a card into a slot provisioned for a different card, all LEDs turn off.

If the red FAIL LED is on continuously or the LEDs behave erratically, the card is not installed properly. Remove the card and repeat Steps 3 to 6.

Stop. You have completed this procedure.
