1.3 Rack Installation


Caution   The chassis must be mounted on a rack that is permanently affixed to the building to maintain stability.

The ONS 15454 SDH is mounted in an ETSI equipment rack. The shelf assembly projects 40 mm from the front of the rack. The shelf assembly is 431.8 mm wide with no mounting brackets (ears) attached, and 535 mm wide with brackets attached. The shelf assembly measures 616.5 mm high and 280 mm deep. Ring runs are not provided by Cisco and can hinder side-by-side shelf installation where space is limited.

You can install up to three ONS 15454 SDHs in an ETSI rack. The ONS 15454 SDH must have 40 mm of airspace below an installed shelf assembly to allow air flow to the fan intake. If an ONS 15454 SDH is installed below a previously installed shelf assembly, the air ramp between the two provides sufficient air flow and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454 SDH.

A node should be mounted at the bottom of the rack if it is the only unit in the rack. When mounting a node 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.


Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 45°C (113°F).


Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety


Warning Care must be given when connecting nodes to the supply circuit so that wiring is not overloaded.


Figure 1-1   ONS 15454 SDH dimensions


1.3.1 Mount a Single Node

Mounting the ONS 15454 SDH in a rack requires a minimum of 616.5 mm of vertical rack space (plus 40 mm for air flow). To ensure the mounting is secure, use two to four M6 mounting screws for each side of the shelf assembly. Figure 1-2 shows the rack-mounting position for the ONS 15454 SDH. In a single node configuration, one air-ramp on the top and one air-ramp on the bottom of the node is recommended.


Figure 1-2   Mounting an ONS 15454 SDH in a rack


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. (See the "Remove the Front Door" Procedure).

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


Step 1   Choose one or two mounting hole(s) on each side where the mounting brackets will be inserted.

Step 2   Using the hex tool that was included with the assembly, install 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 3   Lift the shelf assembly to the desired rack position and place it on the set screws.

Step 4   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 5   Install one mounting screw in each side of the assembly.

Step 6   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 future slippage.

Step 7   Using the hex tool, remove the temporary set screws.





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


Step 1   Lift the shelf assembly to the desired position in the rack.

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

Step 3   Have one person hold the shelf assembly in place while the other person installs one mounting screw in each side of the assembly.

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


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





1.3.2 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 mounting is secure, use one or two M6 mounting screws for each side of the shelf assembly. Figure 1-3 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.


Figure 1-3   Mounting the air ramp in a rack


Procedure: Mount the Air Ramp in a Rack


Step 1   Lift the air ramp to the desired rack position.

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.





1.3.3 Mount Multiple Nodes

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

Procedure: Mount the Shelf Assembly in a Rack


Step 1   Mount the first ONS 15454 SDH in the bottom of the rack.

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

Step 3   Repeat the procedure with the second ONS 15454 SDH and the second air ramp.

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


Note   The ONS 15454 SDH must have 40 mm of airspace 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 the space for air flow. However, if the ONS 15454 SDH is installed above third-party equipment, 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 generate heat upward into the ONS 15454 SDH. The top of the third-party unit should be a non-combustible surface when an air ramp is not installed between the ONS 15454 SDH and the third-party unit.





1.3.3.1 Three-Node Configuration

A single ONS 15454 SDH node can accommodate up to 120 DS-3/E-3 or 140 E1 drops. If you need to drop more 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 co-located 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   A three-node fiber-optic bus configuration


1.3.3.2 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 fuse and alarm panel, two air ramps and two cable-management trays. A three-shelf ONS 15454 SDH bay assembly is shown in Figure 1-5.

1.8.2 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 1-4 shows MIC-C/T/P pin assignments.

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

1.9 Card Installation

This section describes how to install ONS 15454 SDH cards. Most card installation procedures are the same. The XC10G and TCC-I installation procedures are different from the main procedure, so they are combined in a separate procedure. The card installation order is important. Here is the proper sequence:

1. TCC-I cards

2. XC10G cards

3. Optical cards

4. Electrical cards

5. Ethernet cards


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.


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 shelf assembly backplane. When the card ejectors are fully closed, the cards plug into the assembly backplane. Figure 1-14 shows card installation.


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


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.


Warning Class-I (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.


Caution   The laser of the OC-192 LR/STM64 LH 1550 is active when the card is booted and the safety key is in the on position (labeled 1). The port does not need to be in service for the laser to be active. The laser is off when the safety key is in the off position (labeled 0).


Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.


Figure 1-14   Installing cards in the ONS 15454 SDH


Procedure: Install ONS 15454 SDH Cards


Step 1   Open the card ejectors.

Step 2   Slide the cards along the guide rails into the card slot.

Step 3   Close the ejectors.





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 - 4 and 14 - 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 cross-connect (XC10G) cards.


Note   Slot 9 is intended for future use.

Slots 3 and 15 can host E1N-14 and DS3i-N-12 cards that are used in 1:N protection.


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 1-7 shows the slot and card symbol definitions.

Table 1-7   Slot and Card Symbols

* When used as a protect card, the card does not have a physical external connection. The protect card connects to the working card(s) through the backplane and becomes active when the working card fails. The protect card then uses the physical connection of the failed card.

Procedure: Install the TCC-I and XC10G Cards

Although the installation procedure is the same for both TCC-I and XC10G cards, you must install the TCC-I card and let it initialize before installing the XC10G cards. The TCC-I card houses the ONS 15454 SDH software. For a detailed explanation, see "Set up PC and Log into CTC."


Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.


Step 1   Open the card ejectors.

Step 2   Slide the card along the guide rails into the correct slot (Slot 8 or 10 for the XC10G and Slot 7 or 11 for the TCC-I).

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 1-9.

Table 1-9   LED Activity during TCC-I and XC10G Card Installation

Card Type  LED Activity 

TCC-I

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

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. (On the TCC-I card, the ACT/STBY LED
can take several minutes to illuminate when the DCC processor boots.)

XC10G

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 the FAIL LED is illuminated continuously on the TCC-I card, see the tip below about the TCC-I automatic upload.

Step 6   Verify that the ACT/STBY LED is the correct color for the card (green for active, amber for standby). The fan-tray assembly LCD displays the node IP address, the ONS 15454 SDH temperature, and the time of day. The default time and date is 12:00 AM, January 1, 1970.


Tip When a newly installed TCC-I card and the active TCC-I card have different versions of the ONS 15454 SDH software, the new card automatically loads the software version that the active card is running. This is an automatic process that does not need to be initiated. However, the active TCC-I card will not boot up normally during this process. When the new 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 the new card loads the software for approximately 30 minutes, it becomes the standby card and the amber LED is illuminated.





Procedure: Install Optical, Electrical, and Ethernet Cards

Although the installation procedure is the same for optical, electrical, and Ethernet cards, you must install the optical cards before installing the electrical cards.


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.


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.


Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.


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 1-10.

Table 1-10   LED Activity During Optical and Electrical Card Installation

Card Type  LED Activity 

OC3/STM1,
OC12/STM4, OC48/STM16, OC192/STM64

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

3. All LEDs blink once and turn off.

4. The ACT/STBY LED turns on.

E1N-14, DS3i-N-12, E3-12,
Ethernet

1. The red FAIL LED turns on and remains illuminated for 10 to 15 seconds.

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

3. All LEDs blink once and turn off.

4. The ACT/STBY LED turns on.

Ethernet

1. The red FAIL LED turns on and remains illuminated for 10 to 15 seconds.

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.






Caution   An unused card slot should be filled with a blank faceplate (Cisco P/N 15454E-BLANK). The blank faceplate ensures proper air flow when operating the ONS 15454 SDH. An unused FMEC slot should be filled with a blank Faceplate (Cisco P/N 15454E-BLANK-FMEC). The blank faceplate ensures proper functionality without EMC disturbances.

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

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 1-15.


Figure 1-15   A gigabit interface converter


Table 1-11 shows the available GBICs.

15454E-GBIC-ZX=

Procedure: Install Gigabit Interface Converters


Step 1   Remove the GBIC from its protective packaging.

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 1-16).

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.


Figure 1-16   Installing a GBIC on an E1000-2 card


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-I laser products. These products have been tested and comply with Class-I limits.


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

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.

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





Procedure: Remove a Gigabit Interface Converter


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

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 FMEC Card Installation


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

1.11 Fiber-Optic Cable Installation

This section explains how to install optical fibers on OC-N/STM-M cards.


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

ONS OC-N/STM-M cards feature SC connectors. 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 ONS 15454 SDH optical card ports, the top connector is transmit and the bottom connector is receive. Cisco recommends that the transmit and receive and the working and protect fibers be labeled at each end of the fiber span to avoid confusion. For information about fiber cable management, see the "Optical Cable Management" section.


Warning Class-I (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.


Caution   The laser is active 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 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

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.


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/STM-64 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.

1.12 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 EIAs 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 Cat-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.

1.12.1 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.


Figure 1-21   Routing fiber-optic cables on the optical-card faceplate


Procedure: Route Fiber-Optic Cables in the Shelf Assembly


Step 1   Open the fold-down front door on the cable-management tray.

Step 2   Route the cable on the card faceplate through the fiber clip on the faceplate.

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.

1.12.2 Coaxial Cable Management

Coaxial cables connect to FMEC-E1, FMEC-E3/DS3, and MIC-C/T/P cards on the ONS 15454 SDH EFCA.


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 feet) versus 137 m (450 feet) 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 foot) section of the RG179, you can attach a maximum length of 133 m (437 feet) of RG59. When using a 9-m (30-foot) section of RG179, you can attach a maximum length of 95 m (311 feet) 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 feet) for the DS-3 data rate. The attenuation of RG179 is 6.3 db/30 m (6.3 db/100 feet). 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.





1.12.3 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.

1.12.4 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.

1.12.5 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 @ 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.

1.12.6 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.

1.12.7 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.
