Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

OC192 LR/STM64 LH 1550 Card Description
Warning Class I LASER PRODUCT (complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice 50, dated July 26, 2001)
The OC192 LR/STM64 LH 1550 card provides one long-range SONET/SDH OC-192/STM-64 port compliant with ITU G.707, G.957, and Telcordia GR-1377 and GR-253. The card port operates at 9.953 Gbps over unamplified distances up to 80 km, limited by loss and/or dispersion, with different types of fiber such as C-SMF or dispersion-compensated fiber. The card supports VT1.5, VC-12, and non-concatenated or concatenated payloads.
Figure 1 shows the OC192 LR/STM64 LH 1550 faceplate and a block diagram of the card. Figure 2 shows an enlarged view of the faceplate warning.
Note You can differentiate this OC-192/STM-64 card (15454-OC192-LR2, 15454E-L64.2-1) from the OC-192/STM-64 card with the product ID 15454-OC192LR1550 by looking at the faceplate. This card does not have a laser on/off switch.

Caution
You must use a 14 to 28 dB (20 recommended) fiber attenuator when connecting a fiber loopback to an OC192 LR/STM64 LH 1550 card. Never connect a direct fiber loopback because this will damage the OC-192/STM-64 card's optical receiver.
You can install OC192 LR/STM64 LH 1550 cards in any high-speed slot on the ONS 15454 and provision the card as a drop or span card in a two-fiber or four-fiber BLSR, path protection, ADM (linear) configuration, or as a regenerator for longer span reaches.
The OC-192 card port features a 1550 nm laser and contains a transmit and receive connector (labeled) on the card faceplate.
Warning On the OC-192/STM-64 card, the laser is on when the card is booted. The port does not have to be in service for the laser to be on.
The card uses a dual SC connector for optical cable termination. The card supports 1+1 unidirectional and bidirectional facility protection. It also supports 1:1 protection in four-fiber bidirectional line switched ring applications where both span switching and ring switching may occur.
The OC192 LR/STM64 LH 1550 card detects SF, LOS, or LOF conditions on the optical facility. See the Cisco ONS 15454 Troubleshooting Guide for a description of these conditions. The card also counts section and line BIT errors from B1 and B2 byte registers in the section and line overhead.
OC192 LR/STM64 LH 1550 Card-Level Indicators
The OC192 LR/STM64 LH 1550 card has three card-level LED indicators.
Table 1 OC192 LR/STM64 LH 1550 Card-Level Indicators
|
Card-Level Indicators
|
Description
|
|
Red FAIL LED
|
The red FAIL LED indicates that the card's processor is not ready. Replace the card if the red FAIL LED persists. |
|
ACT/STBY LED
Green (Active)
Amber (Standby)
|
When the ACTV/STBY LED is green, the OC-192 card is operational and ready to carry traffic. When the ACTV/STBY LED is amber, the OC-192 card is operational and in standby (protect) mode. |
|
Amber SF LED
|
The amber SF LED indicates a signal failure or condition such as LOS, LOF or high BERs on the card's port. The amber SF LED also illuminates when the transmit and receive fibers are incorrectly connected. When the fibers are properly connected, the light turns off. |
OC192 LR/STM64 LH 1550 Port-Level Indicators
You can find the status of the OC192 LR/STM64 LH 1550 card port using the LCD screen on the ONS 15454 fan-tray assembly. Use the LCD to view the status of the port or card slot; the screen displays the number and severity of alarms for a given port or slot. See the Cisco ONS 15454 Troubleshooting Guide for a complete description of the alarm messages.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or 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. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
OC192 LR/STM64 LH 1550 Compatibility
For SONET applications, use the XC10G card, the TCC+/TCC2 card, the 15454-SA-ANSI or 15454-SA-HD shelf assembly, and Software R4.0 or higher to enable the OC192 LR/STM64 LH 1550 card.
For SDH applications, use the XC-VXC-10G card, the TCC2, the 15454E-SA-ETSI shelf assembly, and Release 4.0 or higher to enable the STM-64 LH 1550 card.

Install the OC192 LR/STM64 LH 1550 Card
Use this section if you are installing the OC192 LR/STM64 LH 1550 card for the first time. After you become familiar with ONS 15454 card installation and boot up, use this section as a reference. For information about fiber optic cable installation, see the Cisco ONS 15454 Procedure Guide.
Caution
Always use the supplied electrostatic discharge (ESD) wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf assembly and ensure the shelf assembly is properly grounded.
OC192 LR/STM64 LH 1550 cards have electrical plugs that plug into electrical connectors on the shelf assembly backplane. When the ejectors are fully closed, the card plugs into the shelf assembly backplane. Figure 3 shows general card installation in an ONS 15454 SONET shelf.
Figure 3 Installing an ONS 15454 Card in a SONET Shelf
Although the installation procedure is the same for optical and electrical, you must install the optical cards before installing the electrical cards. Install the OC-192 card in Slot 5, 6, 12, or 13.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or 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. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Warning The laser is on when the card is booted. The port does not have to be in service for the laser to be on.
Caution
You must use a 14 to 28 dB (20 recommended) fiber attenuator when connecting a fiber loopback to an OC192 LR/STM64 LH 1550 card. Never connect a direct fiber loopback. Using fiber loopbacks causes irreparable damage to the OC-192 card. A Tx to Rx connection that is not attenuated will damage the receiver.
Note Because all other cards boot from the active TCC+/TCC2 card, at least one TCC+/TCC2 card must be installed in order to boot the OC-192 card.
Step 1 Open the card ejectors.
Step 2 Slide the card along the guide rails into the correct slot.
Step 3 Close the ejectors.
Step 4 Verify that power is applied to the shelf assembly.
Step 5 Verify the LED activity, as described in Table 2.

1. The red FAIL LED turns on for 20 to 30 seconds. 2. The red FAIL LED blinks for 35 to 45 seconds. 3. All LEDs blink once and turn off for 5 to 10 seconds. 4. The ACT/STBY LED becomes amber. The signal fail (SF) LED can persist until all card ports connect to their far end counterparts and a signal is present. |
Step 6 When you have displayed Cisco Transport Controller (CTC) on your workstation, verify that the card appears in the correct slot on the CTC node view. See the Cisco ONS 15454 Procedure Guide for CTC information and provisioning instructions.
