When mounting a shelf assembly in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Procedure: Mount Multiple Shelf Assemblies in a Rack

Purpose

This procedure allows multiple shelves to be assembled in a rack.

Tools/Equipment

  • Hex tool
  • M6 mounting screws

Onsite/Remote

Onsite


Note   The ONS 15454 SDH requires 616.5 mm (minimum) of vertical rack space and 40 mm below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 SDH is installed above a shelf assembly, the air ramp between the shelves provides space for air flow. When using third-party equipment above the ONS 15454 SDH, provide a minimum of 40 mm between the third-party unit and the bottom of the ONS 15454 SDH. The third-party equipment must not vent heat upward into the ONS 15454 SDH.


Step 1   Mount the first ONS 15454 SDH in the bottom of the rack using the "Mount the Shelf Assembly in a Rack (One Person)" procedure or the "Mount the Shelf Assembly in a Rack (Two People)" procedure.

Step 2   Mount the air ramp above the ONS 15454 SDH.

Step 3   Repeat this procedure for every ONS 15454 SDH you need to install.

Step 4   Install the third-party fuse and alarm panel in the top space.





1.2.3.1 Three-Node Configuration

A single ONS 15454 SDH can accommodate up to 120 DS-3/E-3 or 140 E-1 drops. If you need to drop more DS-3s, E-3s, or E-1s than the maximum allowed for a single node, you can link multiple nodes using a fiber-optic bus. However, you cannot merge multiple nodes into a single ONS 15454 SDH. You can use STM-4, STM-16, or STM-64 fiber spans to link the nodes as you would link any other network nodes. Nodes can be colocated in a facility to aggregate local traffic.

Figure 1-4 shows a three-shelf node setup. Each shelf assembly is identified as a separate node in Cisco Transport Controller (CTC), the ONS 15454 SDH software interface. Traffic must be mapped using CTC cross-connect options. In the figure, each node uses redundant fiber-optic cards. Node 1 uses redundant STM-N transport and STM-N bus cards for a total of four cards. Nodes 2 and 3 each use two redundant STM-N bus cards for a total of four cards, with eight free slots remaining. The three-node example presented here is one of many ways to set up a multiple-node configuration.


Figure 1-4   Three-node fiber-optic bus configuration


1.2.4 Mount the Air Ramp

The air ramp is needed if you install more than one shelf in the ETSI rack. Install the air ramp below the top shelf assembly. To ensure the air ramp is secure, use one or two M6 mounting screws for each side of the shelf assembly. Figure 1-5 shows the rack-mounting position for the air ramp.

1.6.2 Timing Installation

The MIC-C/T/P provides 1.0/2.3 Miniature Coax connectors that are used for timing input and output. The bottom connectors are for "1" timing, and the top connectors are for "2" timing. In each case, the left connector is the input and the right connector is the output. The input connectors for timing provide a 75-ohm termination. System cables are available that can convert timing clocks from 75 ohms to 100/120 ohms. Table 1-5 shows MIC-C/T/P pin assignments.

A high-impedance option (> 3 kohms or greater) is possible through a jumper on the MIC-C/T/P FMEC. You can change the top timing input to high impedance by removing the jumper on P3 on the MIC-C/T/P FMEC. You can change the bottom timing input to high impedance by removing the jumper on P2 on the MIC-C/T/P FMEC.


Note   Refer to ITU-T G.813 for rules about provisioning timing references.

Step 3   Verify that the FMEC appears in the correct slot in the CTC node view.

Step 4   Verify that the FMEC is white in the CTC node view.


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.





1.8 Installing the Common Control Cards

This section describes how to install the common control cards. You will need two Timing, Communication, and Control-International (TCC-I) cards, and two 10 Gigabit Cross Connect (XC10G) cards per node. This section also describes how to install the Alarm Interface Controller-International (AIC-I) card if required.


Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the back panel of the shelf assembly with your hand or any metal tool due to electrical hazard.


Caution   Always use the supplied ESD wristband when working with a powered ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.


Note   When installing cards, let each card completely boot before installing the next card.

Follow the recommended card installation order:

1. Complete the "Install the TCC-I Cards" procedure.

2. Complete the "Install the XC10G Cards" procedure.

3. Complete the "Install the Alarm Interface Controller (AIC-I) Card" procedure, if necessary.

4. Turn to the table of contents, list of procedures, or index to locate any other procedures that you need to perform for your site.

Procedure: Install the TCC-I Cards

Purpose

This procedure installs redundant TCC-I cards. The first card you install in the ONS 15454 SDH must be a TCC-I, and it must initialize before you install any cross-connect or traffic cards.

Tools/Equipment

Two TCC-I cards per node

Prerequisite Procedures

Measure the voltage.

Onsite/Remote

Onsite


Step 1   Open the latches/ejectors of the first TCC-I card that you will install.

Step 2   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 (Slot 7 or 11).

Step 3   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 into the back panel of the shelf assembly. Ensure that you cannot insert the card any further. If you insert a card into a slot provisioned for a different card, all LEDs turn off.

Step 4   Verify the LED activity, as follows:

1. The red FAIL LED turns on and remains illuminated for 20 to 30 seconds. If the red FAIL LED does not illuminate, check the power.

2. The red FAIL LED blinks for 35 to 45 seconds.

3. The red FAIL LED remains illuminated for 5 to 10 seconds.

4. All LEDs (including the CRIT, MAJ, MIN, REM, SYNC, and ACO LEDs) blink once and turn off for 5 to 10 seconds.

5. The ACT/STBY LED turns on. (The ACT/STBY LED may take several minutes to illuminate while the data communications channel [DCC] processor boots.)


Note    Alarm LEDs may be illuminated; disregard alarm LEDs until you are logged into CTC and can view the Alarms tab.


Note    When a newly installed TCC-I card has a different version of the ONS 15454 SDH software installed than the version running on the active TCC-I, the newly installed TCC-I card automatically copies the software version running on the active TCC-I. You do not need to do anything in this situation. However, the loading TCC-I card will not boot up in the normal manner. When the card is first inserted, the red FAIL LED stays on for a short period. The FAIL LED then blinks normally and all LEDs go dark. The FAIL LED and the ACT/STBY LED flash alternately every 30 to 45 seconds as the new software loads onto the new TCC-I card. After loading the new software for approximately 30 minutes, the TCC-I card becomes the standby card and the amber LED is illuminated.

Step 5   Verify that the ACT/STBY LED is green for active. The IP address for the node, the temperature of the ONS 15454 SDH, and the time of day will be displayed on the LCD. The default time and date is 12:00 AM, January 1, 1970.

Step 6   The LCD cycles through the IP address, node name, and software version. Verify that the correct software version displays on the LCD.

Step 7   If the LCD shows the correct software version, continue with Step 8. If the LCD does not show the correct software version, upgrade the software or remove the TCC-I card and install a replacement card.

Step 8   Open the latches/ejectors of the second TCC-I card and repeat Step 2 to Step 7. The second TCC-I ACT/STBY LED should be amber for standby.

Use of controls or adjustments or performance of procedures other than those specified can result in hazardous radiation exposure.


Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the back panel of the shelf assembly with your hand or any metal tool due to electrical hazard.


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.


Caution   Before installing an OC192 LR/STM64 LH 1550 card, make sure the safety key on the faceplate is in the off position (labeled 0). When the safety key is in the on position (labeled 1), the laser is activated.


Note   The optical (STM-N) card faceplates have SC connectors. Fiber-optic cables are routed to the front of cards. Electrical cards (such as the E1-N-14, the E3-12, and the DS3i-N-12) require EFCAs as cable-connection points for the shelf assembly.


Step 1   Open the card ejectors.

Step 2   Slide the card along the guide rails into the correct slot (Figure 1-15).


Figure 1-15   Installing cards in the ONS 15454 SDH


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 1-12.

2. The red FAIL LED blinks for 30 to 40 seconds.

3. All LEDs blink once and turn off.

4. The ACT LED turns on.

Step 6   Verify that the ACT or ACT/STBY LED is on. The signal fail (SF) LED can persist until all card ports connect to their far-end counterparts and a signal is present.

Step 7   Use CTC to verify that the card appears in the correct slot on the CTC node view. See "Set Up PC and Log Into CTC" for CTC information and setup instructions.





1.9.2 Card Software Installation

After you install an ONS 15454 SDH card in a valid card slot, the card software automatically updates to the version that operates correctly with the system software installed on the TCC-I. When the TCC-I is writing to the active or standby TCC-I, its Active or Standby LED will blink. To prevent memory corruption, do not pull the TCC-I out during this time.

You can use CTC inventory commands to configure the card software. See "Card Provisioning" for more information.

1.9.3 Gigabit Interface Converter

Gigabit Interface Converters (GBICs) are hot-swappable input/output devices that plug into a Gigabit Ethernet card to link the port with the fiber-optic network. The type of GBIC determines the maximum distance that the Ethernet traffic will travel from the card to the next network device.

Cisco provides two GBIC models for the E1000-2-G card and three for the G1000-4 card. The E1000-2-G supports the 15454E-GBIC-SX= for short-reach applications and the 15454E-GBIC-LX= for long-reach applications. The short-reach model connects to multimode fiber up to 550 m long. The long-reach model requires single-mode fiber up to 10 km long. The G1000-4 card supports both the 15454E-GBIC-SX= and 15454E-GBIC-LX= and additionally the 15454E-GBIC-ZX= for extra long-reach applications on the 1550-nm wavelength for up to eighty kilometers. Because the GBICs are very similar in appearance, check the GBIC label carefully before installing it. For a description of GBICs and their capabilities, see "Ethernet Operation." A Gigabit Interface Converter is shown in Figure 1-16.

Step 1   Disconnect the network fiber cable from the GBIC SC connector.


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

Step 2   Release the GBIC from the slot by simultaneously squeezing the two plastic tabs on each side of the GBIC.

Step 3   Slide the GBIC out of the Gigabit Ethernet module slot. A flap closes over the GBIC slot to protect the connector on the Gigabit Ethernet card.





1.10 Fiber-Optic Cable Installation

To install fiber-optic cables in the ONS 15454 SDH, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the ONS 15454 SDH cards. On optical card ports, the top connector is transmit and the bottom connector is receive. Cisco recommends that you label the transmit and receive and the working and protect at each end of the fiber span to avoid confusion. For information about fiber cable management, see the "Optical Cable Management" section.


Warning Class-1 (21 CFR 1040.10 and 1040.11) and Class-1M (IEC 60825-1 2001-01) laser products.


Warning Invisible laser radiation can 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 can pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified can result in hazardous radiation exposure.


Warning The laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).


Note   Do not use fiber loopbacks with the OC192 LR/STM64 LH 1550 card unless you are using a 20-dB attenuator. Never connect a direct fiber loopback. Using fiber loopbacks causes irreparable damage to the OC192 LR/STM64 LH 1550 card.

Procedure: Install Fiber-Optic Cables on STM-N Cards

Onsite/Remote

Onsite


Note   Clean and inspect all fiber connectors thoroughly. Dust particles can degrade performance. Put caps on any fiber connectors that are not used.


Step 1   Place the SC connector in front of the connection point on the card faceplate. Each card supports at least one transmit and one receive connector to create an optical carrier port. Figure 1-18 shows the cable location.


Figure 1-18   Installing fiber-optic cables


Step 2   Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point.

Step 3   Gently push the cable connector into the faceplate connection point until the connector snaps into place.

Step 4   Route fiber cables through the cable retaining clips on the optical card faceplate into the cable management tray on the bottom of the shelf assembly.

Step 5   From the cable management tray, route the fiber cables out of the nearest side of the shelf assembly through the cutout holes.





Procedure: Install the Fiber Boot

Purpose

Use this procedure to install fiber boots. Cisco provides clear plastic fiber boots for the STM-1, STM-4, and STM-16 cards. The boots prevent hanging fibers from bending too sharply and degrading performance. The boots also prevent the front door from interfering with hanging fibers. Figure 1-19 shows the fiber boot attachment. You can install the fiber boots on the fiber-optic cables before or after the fibers are attached to the optic card.

Tools/Equipment

Fiber boot

Note   The fiber boot does not support the OC-48 IR/STM-16 SH AS 1310, OC-48 LR/STM-16 LH AS 1550, or OC-192 LR/STM64 LH 1550 cards. The boots are not necessary for these cards because of the angled SC connectors on the cards.


Step 1   Position the open slot of the fiber boot under the fiber cable.

Step 2   Push the fiber cable down into the fiber boot.

Step 3   Twist the fiber boot to lock the fiber cable into the tail end of the fiber boot.

Slide the fiber boot forward along the fiber cable until the fiber boot fits snugly onto the end of the SC cable connector, (see Figure 1-19).

1.11 Cable Routing and Management

The ONS 15454 SDH cable management facilities include the following:

  • Cable-management clips on optical card faceplates
  • A cable-routing channel that runs the width of the shelf assembly
  • Plastic horseshoe-shaped fiber guides at each cable-routing channel opening that maintain the proper fiber-bend radius
  • A fold-down door that provides access to the cable-management tray
  • Cable tie-wrap facilities on Electrical Interface Assembly (EIA)s that secure cables to the cover panel
  • Reversible jumper-routing fins that enable you to route cables out of either side by positioning the fins as desired
  • Jumper-slack-storage reels (2) on each side panel that reduce fiber slack between connected devices

  • Note   You can remove the fiber guide to create a larger opening (for example, if you need to route Category 5 Ethernet cables out the side). To remove the fiber guide, take out the three screws that anchor it to the side of the shelf assembly.


    Note   To remove the reels, unscrew the screw in the center of each reel.

Figure 1-20 shows the cable management facilities that you can access through the fold-down front door, including the cable-routing channel and the jumper routing fins.


Figure 1-20   Managing cables on the front panel


1.11.1 Optical Cable Management

Optical cables connect to the SC connectors on the faceplates of optical cards and GBICs. Route optical cables down through the fiber management clips on the optical card faceplate (shown in Figure 1-21) or, if the optical cables are connected to GBICs, route them down through the jumper routing fins. (Ethernet cards do not have fiber management clips.) Route optical cables into the cable management area of the shelf assembly, through a cutout in the nearest side of the assembly, and onto the side of the assembly. A hinged panel on the front of the shelf assembly folds down to provide access to the cable-management tray.

Procedure: Route Fiber-Optic Cables in the Shelf Assembly

Purpose

Use this procedure to route optical cable neatly into the cable management area.

1.11.2 Coaxial Cable Management

Purpose

Use this procedure to route coaxial cable in the cable management area. Coaxial cables connect to FMEC-E1, FMEC-E3/DS3, and MIC-C/T/P cards on the ONS 15454 SDH EFCA.

Tools/Equipment

Coaxial cable

Prerequisite Procedures

"Install ONS 15454 SDH FMECs" procedure

Onsite/Remote

Onsite


Step 1   Route the coaxial cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The rubber-coated edges of the side cutouts prevent the cables from chafing.


Note    When using the coaxial cable with 1.0/2.3 Miniature Coax connectors, remember that the maximum distance available depends on the loss of the cable. Generally, thinner cable has a lower maximum distance available than standard cable. If, for example, you only use the RG179 cable, the maximum available distance is 15 m (50 ft) versus 137 m (450 ft) available with the larger RG59 cable.

Step 2   Use short pigtails to terminate the shelf assembly.

Step 3   Use standard coaxial cable connected to the thinner cable for the remainder of the cable run. When using a 3-m (10-ft) section of the RG179, you can attach a maximum length of 133 m (437 ft) of RG59. When using a 9-m (30-ft) section of RG179, you can attach a maximum length of 95 m (311 ft) of RG59.

The shorter maximum distance for RG179 is due to a higher attenuation for the thinner cable. The attenuation for RG59 cable (based upon testing with Belden 923, the equivalent of 328A cable) is ~1.0 dB/30 m (~1.0 dB/100 ft) for the DS-3 data rate. The attenuation of RG179 is 6.3 db/30 m (6.3 db/100 ft). Use a cable loss figure of 5.0 dB for calculations. When using different types of coaxial cable, refer to the data sheets of these cables for loss calculation.





1.11.3 FMEC-DS1/E1 Cable Management

DB-37 cables connect to FMEC-DS1/E1 on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The rubber-coated edges of the side cutouts prevent the cables from chafing.

1.11.4 Alarm Cable Management

Alarm cables connect to the MIC-A/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The rubber-coated edges of the side cutouts prevent the cables from chafing.

1.11.5 Timing Cable Management

Coaxial timing cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Cable attenuation is allowed up to 6 dB at 2 MHz. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.

1.11.6 Craft Cable Management

Craft cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.

1.11.7 LAN Cable Management

LAN cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.
