Installing Cisco ONS 15454 SONET/SDH
Product Names: 15454-OPT-BST
This document provides a card description, specifications, and installation procedure for the dense wavelength division multiplexer (DWDM) OPT-BST card. The OPT-BST card is compatible with Cisco ONS 15454 SONET (ANSI) and Cisco ONS 15454 SDH (ETSI) shelf assemblies. Use this document in conjunction with the Cisco ONS 15454 DWDM Procedure Guide when working with OPT-BST cards.
This document contains the following sections:
OPT-BST Card Description
Optical amplifiers are used in amplified nodes such as hub nodes, amplified OADM nodes, and line amplifier nodes. There are two forms of amplifiers, the Optical Preamplifier (OPT-PRE) and the Optical Booster (OPT-BST) amplifier. The optical amplifier card architecture includes an optical plug-in module with a controller that manages optical power, laser current, and temperature control loops. The amplifier also manages communication with the TCC2 or TCC2P card and OAM&P functions such as provisioning, controls, and alarms.
Optical amplifiers have a linear power feature that enables them to be kept in the constant gain mode. The OPT-BST gain range is 5 to 20 dB in constant gain mode and output power mode. In constant power mode, automatic power control (APC) requirements change. The change occurs because span loss degradation does not effect the system, and amplifiers cannot automatically modify the output power for variations in the number of channels when a failure occurs.

The OPT-BST card is designed to support 64 channels at 50-GHz channel spacing. The OPT-BST is a C-band DWDM erbium-doped fiber amplifier (EDFA) with optical service channel (OSC) add-and-drop capability. When an ONS 15454 has an OPT-BST installed, only the OPT-BST needs to process the OSC. The OPT-BST card can be installed in Slots 1 to 6 and 12 to 17. To control the gain tilt, the OPT-BST is equipped with a built-in VOA.
The OPT-BST features include:
• Fixed gain mode (with programmable tilt)
•True variable gain
•Fast transient suppression
•Non-distorting low-frequency transfer function
•Provisionable maximum output power
•Fixed output power mode (mode used during provisioning)
•Constant drive current mode (test mode)
•MAL for fiber based DCU
•ASE compensation in fixed gain mode
•Full monitoring and alarm handling with provisionable thresholds
•Optical safety features, including signal loss detection and alarming, fast power down control, and reduced maximum output power in safe power mode
•OSRI, which is a feature capable of shutting down the optical output power or reducing the power to a safe level (automatic power reduction)
•ALS, which is a safety mechanism used in the event of a fiber cut
OPT-BST Card Level Indicators
The OPT-BST card has three card-level LED indicators.
OPT-BST Port-Level Indicators
You can find the status of the card ports using the LCD screen on the ONS 15454 ANSI 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.
The OPT-BST amplifier has eight optical ports located on the card faceplate:
•MON Rx is the output monitor port (receive section).
•MON Tx is the output monitor port.
•COM Rx is the input signal port.
•LINE Tx is the output signal port.
•LINE Rx is the input signal port (receive section).
•COM Tx is the output signal port (receive section).
•OSC Rx is the OSC add input port.
•OSC Tx is the OSC drop output port.

Install the OPT-BST Card
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
Warning Class 1M laser radiation when open. Do not view directly with optical instruments. Statement 1053
Caution Always use the supplied 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.
Caution Do not install the DWDM cards until you are directed to do so during DWDM node turn up. Refer to the Cisco ONS 15454 DWDM Procedure Guide for detailed installation instructions.
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.
Note When you install a card, the node begins running automatic node setup (ANS) to determine what kind of site you are installing. Amplifier power control (APC) is automatically enabled after ANS initializes and a channel has been provisioned. To provision a DWDM channel, refer to the Cisco ONS 15454 DWDM Procedure Guide.
Figure 4 shows general card installation.
Figure 4 Installing an ONS 15454 Card in the ANSI Shelf Assembly
Step 1 Plan your node installation or consult the site plan. As soon as you begin installing cards, ANS determines what kind of site to set up based on the following parameters:
•Hub site—Two 32DMX-O and two 32MUX-O cards are provisioned but no AD-xC or AD-xB cards are provisioned
•Terminal—One 32DMX-O and one 32MUX-O card are provisioned, and no AD-xC or AD-xB cards are provisioned
•Line site—Only one OPT-PRE or OPT-BST is provisioned per line direction. (Up to two OPT-PRE and/or two OPT-BST cards can be provisioned in the same shelf.)
•OADM site—At least 1 AD-xC or AD-xB is provisioned and no 32DMX-O or 32MUX-O cards are provisioned
•Unknown—Provisioned cards do not follow any of the previously listed categories.
Step 2 Open the card latches/ejectors.
Step 3 Use the latches/ejectors to firmly slide the DWDM card along the guide rails until the card plugs into the receptacle at the back of the slot.
Step 4 Install the card in any open east and west pair of slots. OPT-BST cards are often installed in Slots 1 and 17.
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/ejectors when the card is not completely plugged in. Ensure that you cannot insert the card any further.
Step 6 Verify the following LED activity:
1. . The FAIL LED turns on for approximately 35 seconds
2. The FAIL LED blinks for approximately 40 seconds
3. All LEDs turn on and then turn off within 5 seconds
4. If new software is being downloaded to the card, the ACT and SF LEDs blink for 20 seconds to 3.5 minutes, depending on the card type
5. The ACT LED turns on
6. The signal fail (SF) LED stays on 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 mimic Step 6, check the following:
•When a physical card type does not match the type of card provisioned for that slot in Cisco Transport Controller (CTC), the card might not boot. In CTC, ensure that the slot is not provisioned for a different card type before assuming 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.
Step 8 Refer to the Cisco ONS 15454 DWDM Procedure Guide for provisioning instructions.
Stop. You have completed this procedure.
