1.2.1 ONS 15454 SDH Bay Assembly

The Cisco ONS 15454 SDH bay assembly simplifies ordering and installing the ONS 15454 SDH because it allows you to order shelf assemblies pre-installed in an ETSI rack. The bay assembly is available in a three-shelf configuration. The three-shelf configuration includes three ONS 15454 SDH shelf assemblies, a slot for third-party fuses and alarm panels, two air ramps and two cable-management trays. A three-shelf ONS 15454 SDH bay assembly is shown in Figure 1-2.

1.2.2 Mount a Single Shelf Assembly

The shelf assembly is most easily installed by two people. However, you can install it alone by using temporary set screws. Reduce extra weight if possible by emptying the shelf assembly and removing the front door. For more information, see the "Open and Remove the Front Door" procedure.

Procedure: Mount the Shelf Assembly in a Rack (One Person)

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. To ensure the mounting is secure, use two to four M6 mounting screws for each side of the shelf assembly. A shelf assembly should be mounted at the bottom of the rack if it is the only unit in the rack.

Step 2   Ensure that the shelf assembly is set for the desired rack size. Figure 1-3 shows the rack-mounting position for the ONS 15454 SDH.

Step 3   Using the hex tool that shipped with the assembly, install the two temporary set screws into the holes that will not be used to mount the shelf. Let the set screws protrude sufficiently to hold the mounting brackets.

Step 4   Lift the shelf assembly to the desired position in the rack.

Step 5   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 6   Install one mounting screw in each side of the assembly.

Step 7   When the shelf assembly is secured to the rack, install the remaining mounting screws.

---

Note    Use at least one set of the horizontal screw slots on the ONS 15454 SDH to prevent slippage.

---

Step 8   Using the hex tool, remove the temporary set screws.

Procedure: Mount the Shelf Assembly in a Rack (Two People)

---

Note    Use at least one set of the horizontal screw slots on the ONS 15454 SDH to prevent slippage.

---

Step 8   Remove the temporary mounting screws.

1.2.3 Mount Multiple Shelf Assemblies

The standard ETSI racks can hold three ONS 15454 SDHs and two air ramps. 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

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 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.

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.

Note   Install the air ramp after you have connected and routed all cables for the ONS 15454 SDH.

Procedure: Mount the Air Ramp in a Rack

Step 2   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 3   Install one mounting screw in each side of the assembly.

Step 4   When the air ramp is secured to the rack, install the remaining mounting screws if necessary.

1.3 Shelf-Assembly and FMEC Cover Removal and Replacement

The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a critical, major, or minor alarm is present anywhere in the ONS 15454 SDH. These LEDs must be visible so technicians can quickly determine if any alarms are present. You can use the LCD to further isolate alarms. See "Alarm Monitoring and Management" for more information.

You can remove the front door of the ONS 15454 SDH to provide unrestricted access to the front of the shelf assembly. An erasable label is pasted on the inside of the front door (Figure 1-6). You can use the label to record slot assignments, port assignments, card types, the node ID, the rack ID, and the serial number for the ONS 15454 SDH.

Note   When you are done installing/servicing the shelf assembly, the door must be reinstalled. The door serves as the electrical closure for the unit.

1.4 Fan-Tray Assembly Installation

The fan-tray assembly is a removable drawer that holds fans and fan-control circuitry for the ONS 15454 SDH. Cisco recommends removing the front door of the chassis when removing or installing the fan-tray assembly. The front of the fan-tray assembly has an LCD screen that provides slot and port-level information for all ONS 15454 SDH card slots, including the number of critical, major, and minor alarms.

Fan speed is controlled by TCC-I card temperature sensors. The sensors measure the input air temperature at the fan-tray assembly. Fan speed options are low, medium, and high. If the TCC-I card fails, the fans automatically shift to high speed. The temperature measured by the TCC-I sensors is displayed on the LCD screen.

Note   Error messages appears on the TCC-I, fan-tray LED, and in CTC when the fan-tray assembly is removed from the shelf or when one fan is not working.

Procedure: Install the Fan-Tray Assembly

The fan-tray assembly is located at the bottom of the ONS 15454 SDH. After you install the fan-tray assembly, you only need to open the drawer if a fan fails, or if you need to replace or clean the fan-tray air filter. Do not operate an ONS 15454 SDH without a fan-tray air filter. Refer to the Maintenance Chapter in the Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide for information about cleaning and maintaining the fan-tray air filter.

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:

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

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.

Procedure: Install the XC10G Cards

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 8 or 10).

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.

---

Step 4   Verify the LED activity, as follows:

1. The red LED turns on and remains illuminated for 20 to 30 seconds.

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

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

4. All LEDs blink once and turn on.

5. The ACT/STBY LED turns on.

---

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

---

---

Note    If the red FAIL LED does not illuminate, check the power.

---

---

Note    If the red FAIL LED is illuminated continuously or the LEDs act erratically, the card is not installed properly. Remove the card and repeat Steps 1 to 4.

---

Step 5   Verify that the ACT/STBY LED is green for active.

Step 6   Use the latches/ejectors to firmly slide the second cross-connect card along the guide rails until the card plugs into the receptacle at the back of the slot (Slot 8 or 10) and repeat Step 2 to Step 4. The second XC10G should have an amber ACT/STBY LED.

Procedure: Install the Alarm Interface Controller (AIC-I) Card

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 9).

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.

---

Step 4   Verify the LED activity, as follows:

1. The red FAIL LED starts blinking 1 second after the card is installed, then blinks for up to 10 seconds until the TCC has detected the AIC-I card.

2. After the TCC detects the AIC-I card, the PWR A and PWR B LEDs illuminate red and the two INPUT/OUTPUT LEDs illuminate green for several seconds.

3. The PWR A and PWR B LEDs turn green, the INPUT/OUTPUT LEDs turn off, and the ACT LEDs illuminates.

---

Note    If the red FAIL LED does not illuminate, check the power.

---

---

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

---

---

Note    If the red FAIL LED is illuminated continuously or the LEDs blink erratically, the card is not installed properly. Remove the card and repeat Steps 1 to 4.

---

Step 5   Verify that the MIC-A/P FMEC provides connection for alarm contacts into and out of the shelf assembly. For more information, see the "Alarm Installation" section.

1.9 Optical, Electrical, and Ethernet Card Installation

This section describes how to install ONS 15454 SDH optical, electrical, and Ethernet cards. The card installation order is important. Here is the proper sequence:

1. TCC-I cards, see the "Install the TCC-I Cards" procedure.

2. XC10G cards, see the "Install the XC10G Cards" procedure.

3. AIC-I cards, see the "Install the Alarm Interface Controller (AIC-I) Card" procedure.

4. Optical cards, see the "Install Optical, Electrical, and Ethernet Cards" procedure.

5. Electrical cards, see the "Install Optical, Electrical, and Ethernet Cards" procedure.

6. Ethernet cards, see the "Install Optical, Electrical, and Ethernet Cards" procedure.

Note   All cards boot from the active TCC-I card, which houses the ONS 15454 SDH software. Therefore, you must install the TCC-I card to boot any other cards. See "Set Up PC and Log Into CTC" for information about the TCC-I card and software versions. See "Install the TCC-I Cards" procedure on page 1-31 for TCC-I installation procedures.

Note   Before installing cards, verify that the power is turned on.

ONS 15454 SDH cards have electrical plugs at the back that plug into electrical connectors on the back panel of the shelf assembly. When the card ejectors are fully closed, the cards plug into the back panel of the shelf assembly. Figure 1-15 shows card installation.

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, or you could shock yourself.

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

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).

Warning Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands and fingers out of the power supply bays and backplane areas.

1.9.1 Slot Requirements

The ONS 15454 SDH shelf assembly has 17 card slots that are numbered sequentially from left to right. Slots 1 to 4 and 14 to 17 are multispeed slots. They can host any ONS 15454 SDH traffic card except OC48 ELR/STM16 EH 100 GHz and OC192/STM64. Slots 5, 6, 12, and 13 are high-speed slots. They can host any ONS 15454 SDH card.

Slots 7 and 11 are dedicated to TCC-I cards. Slots 8 and 10 are dedicated to XC10G cards. Slot 9 is used for the AIC-I card. Slots 3 and 15 can host E1N-14 and DS3i-N-12 cards that are used in 1:N protection schemes.

Note   Do not operate the ONS 15454 SDH with a single TCC-I card or a single XC10G card installed. Always operate the shelf assembly with one working and one protect card of the same type.

Shelf assembly slots have symbols indicating the type of cards that you can install in the slots. Each ONS 15454 SDH card has a corresponding symbol. The symbol on the card must match the symbol on the slot. Table 1-10 shows the slot and card symbol definitions.

Table 1-11 lists the number of ports, line rates, connector options, and connector locations for ONS 15454 SDH optical and electrical cards.

Procedure: Install Optical, Electrical, and Ethernet Cards

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

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.

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.

Table 1-13 shows the available GBICs.

Procedure: Install Gigabit Interface Converters

Step 2   Check the part number to verify that the GBIC is the correct type for your network.

Step 3   Grip the sides of the GBIC with your thumb and forefinger and insert it into the slot on the front panel of the Gigabit Ethernet card (shown in Figure 1-17).

GBICs are hot-swappable and can be installed or removed when the card or shelf assembly is powered and running.

---

Note    GBICs are keyed to prevent incorrect installation.

---

Step 4   Slide the GBIC through the cover flap until you hear a click.

The click indicates the GBIC is locked into the slot.

---

Note    GBICs are Class-1 laser products. These products have been tested and comply with Class-1 limits.

---

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

Step 5   When you are ready to attach the network interface fiber-optic cable, remove the plug from the GBIC and save the plug for future use.

Step 6   Install and route the cable. See the "Optical Cable Management" section for routing instructions.

Procedure: Remove a Gigabit Interface Converter

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

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

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

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 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:

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.

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

Step 2   Route the cable on the card faceplate through the fiber clip on the faceplate (Figure 1-21).

Step 3   GBICs do not have fiber clips. If you are routing optical cable from an E1000-2-G or G1000-4 card, skip to Step 5.

Step 4   Route the cables into the cable-management tray.

Step 5   Route the cables out either side of the cable-management tray and through the cutouts on each side of the shelf assembly. Use the reversible fiber guides to route cables out of the desired side.

Step 6   Close the fold-down front door when all cables in the front compartment are properly routed.

Figure 1-22 shows the fold-down front door of the shelf assembly opened to display the cable-routing channel.

1.11.2 Coaxial Cable Management

---

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.
