DLP-D199 Inspect, Clean, and Replace the Reusable Air Filter

Purpose

This task ensures that the air filter is free from dirt and dust, which allows optimum air flow and prevents dirt and dust from entering the shelf.

Tools/Equipment

Vacuum or detergent and water faucet, spare filter, pinned hex key tool

Prerequisite Procedures

None

Required/As Needed

Inspection required every 30 days. Clean as needed.

Onsite/Remote

Onsite

Security Level

Maintenance or higher



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.



Step 1 Verify that you are replacing a reusable air filter. The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later versions of the ONS 15454 SDH use a reusable air filter.

Step 2 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 may have collected on the filter and proceed to Step 9. Figure 15-1 illustrates a reusable fan-tray air filter in an external filter bracket.

Step 3 If the filter is installed beneath the fan tray and not in the external filter brackets, open the front door of the shelf assembly:

a. Open the front door lock.

The ONS 15454 SDH 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 4 Remove the front door (optional). If you do not want to remove the door, proceed to Step 5:

a. Detach the ground strap from either the door or the chassis by removing one of the Kepnuts.

b. Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.

c. Secure the dangling end of the ground strap to the door or chassis with tape.

Figure 15-1 Reusable Fan-tray Air Filter in an External Filter Bracket (Front Door Removed)

Step 5 Push the outer side of the handles on the fan-tray assembly to expose the handles.

Step 6 Pull the handles and slide the fan-tray assembly one inch out of the shelf assembly and wait until the fans stop.

Step 7 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.

Step 8 Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that may have collected on the filter.

Step 9 Visually inspect the air filter material for dirt and dust.

Step 10 If the reusable air filter contains a concentration of dirt and dust, replace the dirty air filter with a clean air filter (spare filters should be kept in stock) and re-insert the fan-tray assembly. Then, vacuum or wash the dirty air filter under a faucet with a light detergent.


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 SDH cards.

Note Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.


Step 11 If you washed the filter, allow it to completely air dry for at least eight hours.


Warning Do not put a damp filter back in the ONS 15454 SDH.


Step 12 Replace the clean filter:

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

b. If the filter is installed beneath the fan-tray assembly, remove the fan-tray assembly, and slide the dry/clean 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 reusable filter until the fan tray fits correctly.

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


Step 13 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 14 Rotate the retractable handles back into their compartments.

Step 15 If you replace the door, also reattach the ground strap.

Step 16 Close and lock the door.

Step 17 Return to your originating procedure (NTP).

NTP-D163 Restore the Node to Factory Configuration

Purpose

Use this procedure to clear the TCC2 database and restore customer or factory defaults. This process involves uploading the most recent software package and a blank database. This process is performed by the RE-INIT.jar utility, also called the reinitialization (reinit) tool.

Tools/Equipment

Software CD containing Release 3.4 software, the node's NE defaults, and the reinitialization tool. JRE 1.03_02 must also be installed on the computer that you use to perform this procedure.

Security Level

Superuser



Caution If you are restoring the database on multiple nodes, wait until the TCC2 cards have rebooted on each node before proceeding to the next node.


Caution Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinit tool chooses the first product-specific software package in the specified directory if you only use the Search Path field. You may accidentally copy an incorrect database if multiple databases are kept in the specified directory.


Note The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.



Step 1 If you need to install or replace one or more TCC2 cards, see the "DLP-D332 Install the TCC2 Cards" task on page 2-7.

Step 2 If you are using Microsoft Windows, complete the "DLP-D244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)" task.

Step 3 If you are using UNIX, complete the "DLP-D245 Use the Reinitialization Tool to Clear the Database and Upload Software (UNIX)" task.

Stop. You have completed this procedure.


DLP-D244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)

Purpose

This procedure describes how to use the reinitialization tool in Windows. Use this tool to clear the database on the TCC2, upload software, and restore factory or customer defaults.

Tip The revert feature is useful if a maintenance window closes while you are upgrading CTC software. You can revert to the standby software load without losing traffic. When the next maintenance window opens, complete the upgrade and activate the new software load.



Note Reverting to Software R2.2.1 or later load switches to the older software load and its attendant database without affecting traffic or DCC connectivity. This feature requires dual TCC2 cards and CTC Software R2.2.1 or later as the protect version.



Note A revert to a maintenance release software load uses the current active database; therefore, no provisioning is lost. All other reverts do restore the database. (A maintenance release has a three-digit release number, e.g. 2.2.2).



Note Circuits created and provisioning performed after a software load is activated (upgraded to a higher software release) do not reinstate with a revert. The database configuration at the time of activation is reinstated after a revert. This note does not apply to maintenance reverts (e.g. R2.2.2 to R2.2.1), because maintenance releases use the same database.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23 at the node you want to revert. If you are already logged in, continue with Step 2.

Step 2 Record the IP address of that node; the IP address is displayed on the left side in node view.

Step 3 If reverting to a previous software release (not a maintenance release), record any new circuits created since the previous software upgrade because these circuits must be manually recreated (if needed) after the software reversion has taken place.

Step 4 Click the Maintenance > Software tabs.

Step 5 Verify that the protect software is Software R2.2.0 or later. If the protect software is not Software R2.2.0 or later, do not revert.

Step 6 Click Revert. The Revert button activates the protect software load.

Step 7 Click Yes on the revert confirmation dialog box. The ONS 15454 SDH reboots and loses the connection to CTC.

Step 8 Wait until the software upgrade finishes. This may take as long as 30 minutes.

Step 9 When the software upgrade is finished, click the Delete CTC Cache button in the browser window.

Step 10 Completely close the browser.

Step 11 Restart the browser and log back into the node using the IP address recorded in Step 2. See the "DLP-D60 Log into CTC" task on page 3-23.

The browser downloads the CTC applet for the standby software load.

Step 12 If needed, recreate the circuits recorded in Step 3. See Chapter 6, "Create Circuits and Low-Order Tunnels" for specific circuit creation procedures.

Stop. You have completed this procedure.
