Note The shelf assembly ships with external (bottom) brackets that you can use to install the air filter on the bottom of the shelf rather than beneath the fan-tray assembly. When you use the brackets to install the fan-tray air filter, you do not need to remove the fan-tray assembly to access the air filter. Attach the brackets to the bottom of the shelf assembly before installing the rack.



Note If you choose not to install the brackets, install the air filter by sliding it into the compartment at the bottom of the shelf assembly. Each time you remove and reinstall the air filter in the future, you must first remove the fan-tray assembly. Do not install an air filter in both filter locations on any shelf assembly.



Step 1 With the fan-tray assembly removed, place the ONS 15454 face down on a flat surface.


Note Although the filter will work if it is installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter.


Step 2 Locate the three screw holes that run along the left and right sides of the bottom of the shelf assembly.

Step 3 Secure each bracket to the bottom of the shelf assembly using the screws (48-0003) provided in the backplane standoff kit (53-0795-XX).

Each bracket has a filter stopper and a flange on one end. Make sure to attach the brackets with the stoppers and flanges facing the rear of the shelf assembly (the top, if the ONS 15454 is face-down during installation).

Caution Do not operate an ONS 15454 without a fan-tray air filter. A fan-tray air filter is mandatory.


Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 Release 3.1 or later shelf assemblies (15454-SA-ANSI, 800-19857). It includes a pin that does not allow it to be installed in ONS 15454 shelf assemblies released earlier than ONS 15454 Release 3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N 800-0714915454). Installing the 15454-FTA3 in a noncompliant shelf assembly might result in failure of the alarm interface panel (AIP), which in turn, will result in power loss to the fan-tray assembly.


Caution You must place the edge of the air filter flush against the front of the fan-tray assembly compartment when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter, the fan tray, or both.


Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.


Note To install the fan-tray assembly, it is not necessary to move any of the cable-management facilities.



Step 1 Slide the fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.

Note Rather than using the LAN wires, you can use the LAN connection port on the TCC+/TCC2 if preferred. Use either the backplane connection or the TCC+/TCC2 front connection. You cannot use the LAN backplane pins and the LAN connection port on the TCC+/TCC2 simultaneously; however, it is possible for you to make a direct connection from a computer to the LAN connection port on the TCC+/TCC2 while the LAN backplane pins are in use as long as the computer that is connected directly to the TCC+/TCC2 is not connected to a LAN.



Step 1 Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wire or CAT5 UTP Ethernet cable, wrap the wires on the appropriate wire-wrap pins according to local site practice.


Caution Cross talk may result if both receive (Rx) and transmit (Tx) pins connect on the same twisted pair of wires from the CAT5 cable. The two Tx pins need to be on one twisted pair, and the two Rx pins need to be on another twisted pair.

A frame ground pin is located beneath each pin field (FG2 for the LAN pin field). Wrap the ground shield of the LAN interface cable to the frame ground pin. Table 1-3 shows the LAN pin assignments.

Note The TCC2 does not support Ethernet polarity detection. The TCC+ and TCC-I both support this feature. If your Ethernet connection has the incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), the TCC+ or TCC-I will work, but the TCC2 will not. In this event, a standing condition, "Lan Connection Polarity Reversed", will be raised. This issue will most likely be seen during an upgrade or initial node deployment. To correct the situation, ensure that your Ethernet cable has the correct mapping of the wire wrap pins.

Step 1 Tie wrap or lace the coaxial cables according to local site practice and route the cables through the side cutouts on either side of the ONS 15454. The rubber coated edges of the side cutouts prevent the cables from chafing.

Step 2 Use short lengths of pigtail RG179 to terminate the shelf assembly.

Step 3 Use standard RG59 (735A) cable connected to the RG179 for the remainder of the cable run. When using a 10-foot (3.05 m) section of the RG179, you can attach a maximum length of 437 feet (133 m) of RG59 (735A). When using a 30-foot (9.1 m) section of RG179, you can attach a maximum length of 311 feet (94.8 m) of RG59 (735A).

When using the RG179 cable, the maximum distance available (122 feet, 37.2 m) is less than the maximum distance available with standard RG59 (735A) cable (306 feet, 93.3 m). The maximum distance when using the RG59 (734A) cable is 450 feet (137.2 m). The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. Attenuation rates are calculated using a DS-3 signal:

For RG179, the attenuation rate is 59 dB/kft (dB per kilo-foot) at 22 MHz.

For RG59 (735A), the attenuation rate is 23 dB/kft at 22 MHz.

Use a figure of 5.0 for total cable loss when making calculations. Figure 1-23 shows an example of proper coaxial cable routing.

Step 1 Using a voltmeter, verify the office ground and power. (Figure 1-10 shows the power terminals.)

a. Place the black lead (positive) on the frame ground on the bay. Hold it there while completing Step b.

b. Place the red lead (negative) on the fuse power points and alarm panel to verify that they read between -42 VDC and -57 VDC (power) or 0 (return ground).

Step 2 Using a voltmeter, verify the shelf ground and power wiring:

a. Place the black lead (positive) on the RET1 and the red lead on the BAT1 point. Verify a reading between -42 VDC and -57 VDC. If there is no voltage, check the following and correct if necessary:

Battery and ground are reversed to the shelf.

Battery is open or missing.

Return is open or missing.

b. Repeat Step 2 for the RET2 and BAT2 if the B power feed is provided

Step 3 Return to your originating procedure (NTP).
