Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note The air filters are single-use only. They must not be cleaned and reused. This is a Telcordia NEBS requirement, GR-63-CORE Issue 4.



Note Air filters must be inspected every month. If they are dirty or clogged with dust, they must be replaced with a new air filter.



Note If you install the air filter below 15454E-CC-FTA or 15454-CC-FTA, only filters with part numbers 700-23193-01 and 700-23194-01 can be used in this configuration.



Caution Although the air filter can work with older fan trays if it is installed with either side facing up, it is recommended that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the air filter with the metal bracing facing up with 15454E-CC-FTA or 15454-CC-FTA.


Note To install the air filter inside the air ramp unit (15454E-AIR-RAMP or 15454-AIR-RAMP), use the ETSI version of the air filter (15454-FTF2 or 15454E-FTF4).


Step 1 If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful not to dislodge any dust that might have collected on the filter and proceed to Step 8. Figure 6-1 shows the fan-tray air filter in an external filter bracket on an ANSI shelf. Figure 6-2 shows the fan-tray air filter in an external filter bracket on an ETSI shelf.

Step 2 If the filter is installed below the fan tray and not in the external filter brackets, open the front door of the shelf assembly. If the front door is already open, proceed to Step 3.

a. Open the front door lock.

The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.

b. Press the door button to release the latch.

c. Swing the door open.

Step 3 (Optional) Remove the front door using the "DLP-G10 Remove the Front Door" procedure". If you do not want to remove the door or it is already removed, proceed to Step 4.

Step 4 Push the outer side of the handles on the fan-tray assembly to expose the handles.

Step 5 Pull the handles and slide the fan-tray assembly one half inch (12.7 mm) out of the shelf assembly and wait until the fans stop.

Step 6 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.

Step 7 Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that might have collected on the filter.

Step 8 Visually inspect the air filter material for dirt and dust.

Step 9 Replace the air filter with a new one if the air filter is dirty or clogged with dust.


Caution Do not leave the fan tray out of the chassis for an extended period of time because excessive heat can damage the ONS 15454 cards.

Step 10 Replace the air filter:

a. If the air filter is installed in the external filter brackets, slide the new air filter all the way to the back of the brackets.

b. If the filter is installed below the fan-tray assembly, slide the new air filter into the recessed compartment at the bottom of the shelf assembly. Put the front edge of the air filter flush against the front edge of the recessed compartment. Push the fan tray back into the shelf assembly.


Caution If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and readjust the position of the air filter until the fan tray fits correctly.


Note On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly inserted.


Step 11 To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray assembly is activated and displays node information.

Step 12 Rotate the retractable handles back into their compartments.

Step 13 If you removed the door, complete the "NTP-G40 Replace the Front Door" procedure. If not, close and lock the door.

Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 R3.1 and later shelf assemblies (15454-SA-ANSI, P/N: 800-19857; 15454-SA-HD, P/N: 800-24848). The fan-tray assembly includes a pin that prevents it from being installed in ONS 15454 shelf assemblies released before ONS 15454 R3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result from attempting to install the 15454-FTA3 in a incompatible shelf assembly.


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 backplane.


Caution 15454-CC-FTA (ANSI) is compatible with Software R2.2.2 and greater, and shelf assemblies 15454-SA-ANSI and 15454-SA-HD. 15454E-CC-FTA (ETSI) is compatible with Software R4.0 and greater, and shelf assembly 15454-SA-ETSI.


Caution As with the FTA3, the 15454E-CC-FTA and 15454-CC-FTA Fan Fail LED on the front of the fan-tray assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or AIP replacement is required. But the Fan Fail LED on the 15454E-CC-FTA and 15454-CC-FTA will also illuminate when only one power source is connected to the chassis, and or any fuse blows. In such conditions, the Fan Alarm is triggered and the fans run at maximum speed.


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



Step 1 Review Table 6-1 (ANSI) or Table 6-2 (ETSI) to ensure that you have compatible components when replacing the fan-tray assembly. Note the alarms that will be generated when an incompatibility occurs.


Note If you need to determine the hardware that has been installed on a node, click the Inventory tab in node view.

Tools/Equipment

#2 Phillips screwdriver

Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher



Caution Do not use a 2A AIP with a 5A fan-tray assembly; doing so will cause a blown fuse on the AIP.


Caution Always use the supplied ESD wristband when working with a powered ONS 15454. For detailed instructions on how to wear the ESD wristband, refer to the Electrostatic Discharge and Grounding Guide for Cisco CPT and Cisco ONS Platforms.


Caution Do not perform this procedure on a node with live traffic. Hot-swapping the AIP can affect traffic and result in a loss of data. For assistance with AIP replacement, contact the Cisco TAC. See the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section.


Step 1 Review Table 6-1 to ensure that you have compatible components when replacing the ANSI shelf AIP and note the alarms that will occur when an incompatibility occurs.

Step 2 Ensure that all nodes in the affected network are running the same software version before replacing the AIP and repairing circuits:

a. In network view or multishelf view (multishelf mode), click, click the Maintenance > Software tabs. The working software version for each node is listed in the Working Version column.

b. If you need to upgrade the software on a node, refer to the release-specific software upgrade document. No hardware should be changed or circuit repair performed until after the software upgrade is complete. If you do not need to upgrade software or have completed the software upgrade, proceed to Step 3.

Step 3 Record the MAC address of the old AIP:

a. Log into the node where you will replace the AIP. See the "DLP-G46 Log into CTC" task.

b. In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Network tabs.

c. Record the MAC address shown in the General tab.

Step 4 Call Cisco TAC for assistance in replacing the AIP and maintaining the original MAC address. See the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section.

Step 5 Complete the "DLP-G13 Remove the Lower Backplane Cover" in the Cisco ONS 15454 Hardware Installation Guide.

Step 6 Unscrew the two screws that hold the AIP cover in place.

Step 7 Grip the cover and gently pull away from the backplane.


Note On the 15454-SA-HD (P/N: 800-24848), 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves, the AIP cover is clear plastic. On the 15454-SA-ANSI shelf (P/N: 800-19857), the AIP cover is metal.


Step 8 Grip the AIP and gently pull it away from the backplane.

Step 9 Disconnect the fan-tray assembly power cable from the AIP.

Step 10 Set the old AIP aside for return to Cisco.


Caution The type of shelf that the AIP resides in determines the version of AIP that should replace the failed AIP. The 15454-SA-ANSI shelf (P/N: 800-19857) and 15454-SA-HD (P/N: 800-24848) currently use the 5A AIP, (P/N: 73-7665-01). The 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves and earlier use the 2A AIP (P/N: 73-5262-01).


Caution Do not put a 2A AIP (P/N: 73-5262-01) into a 15454-SA-ANSI (P/N: 800-19857) or 15454-SA-HD (P/N: 800-24848) shelf; doing so will cause a blown fuse on the AIP.

Step 11 Attach the fan-tray assembly power cable to the new AIP.

Step 12 Place the new AIP on the backplane by plugging the panel into the backplane using the DIN connector.

Step 13 Replace the AIP cover over the AIP and secure the cover with the two screws.

Step 14 Replace the lower backplane cover and secure the cover with the five screws.

Step 15 In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Network tabs.


Caution Cisco recommends that TCC2/TCC2P/TCC3/TNC/TSC card resets be performed in a maintenance window to avoid any potential service disruptions.
