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 15327 use a reusable air filter.
Step 2 Move any cables that are routed in front of the fan-tray assembly and air filter so you can easily slide the filter out (Figure 14-1).
Step 3 Grasp the metal tab at the edge of the filter and slide the filter out of the bracket while being careful not to dislodge any dust that might have collected on the filter.
Figure 14-1 Removing the Reusable Fan-Tray Air Filter
Step 4 Visually inspect the filter material for dirt and dust.
Step 5 If the reusable air filter contains a concentration of dirt and dust, either vacuum or wash the air filter. Prior to washing the air filter, replace the dirty air filter with a spare clean air filter (spare filters should be kept in stock).
Step 6 Wash the dirty air filter under a faucet with a light detergent. After washing the air filter, allow it to completely air dry for at least eight hours before reusing.
Note Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.
Warning Do not put a damp filter back in the ONS 15327.
Step 7 Slide the clean air filter back into the shelf (Figure 14-2).

Security Level |
Superuser |
Caution
If you are restoring the database on multiple nodes, wait until the XTC 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 reinitialization tool will choose the first product-specific software package in the specified directory if you only use the Search Path field. You might 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 will 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 XTC cards, see the "217 Install the XTCs" procedure.
Step 2 If you are using Microsoft Windows, complete the "DLP-B244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)" task.
Step 3 If you are using UNIX, complete the "DLP-B245 Use the Reinitialization Tool to Clear the Database and Upload Software (UNIX)" task.

Step 8 In the Search Path field, verify that the path to the CISCO15327 folder on the CD drive is listed.
Caution
Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinitialization tool will choose the first product-specific software package in the specified directory if you use the Search Path field instead of the Package and Database fields. You might accidentally copy an incorrect database if multiple databases are kept in the specified directory.
Caution
Before you perform the next step, be sure you are uploading the correct database. You cannot reverse the upload process after you click Yes.
Step 9 Click Go.
Step 10 A confirmation dialog box opens (Figure 14-11). Click Yes.
Step 11 The status bar at the bottom of the screen displays Complete when the node has activated the software and uploaded the database.
Note The Complete message only indicates that the XTC successfully uploaded the database, not that the database restore was successful. The XTC then tries to restore the database after it reboots.
Step 12 If you are logged into CTC, close the browser window and disconnect the straight-through LAN cable from the RJ-45 (LAN) port on the XTC or on the hub or switch to which the ONS 15327 is physically connected. Reconnect your straight-through LAN cable to the LAN port and log back into CTC. See the "22 Set Up CTC Computer to Connect to the ONS 15327" procedure.
Step 13 Manually set the node name and network configuration to site-specific values. See the "25 Set Up Name, Date, Time, and Contact Information" procedure and "169 Set Up CTC Network Access" procedure for information on setting the node name, IP address, mask and gateway, and IIOP port.

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 Provisioning performed after a software load is activated (upgraded to a higher software release) will not reinstate with a revert. The database configuration at the time of activation is reinstated by a revert. This note does not apply to maintenance reverts (for example, 2.2.2 to 2.2.1), because maintenance releases use the same database (a revert to a maintenance release software load will use the current active database; therefore, no provisioning is lost).
Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you will perform the revert. If you are already logged in, go to Step 2.
Step 2 Record the IP address of that node. The address can be obtained using one of the following methods:
•The IP address is displayed on the left side in node view.
•In node (default) view, click the Provisioning > Network > General tabs.
Step 3 If reverting to a previous software release (not a maintenance release), record any new circuits created since the previous software upgrade. These circuits will have to 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 R3.3.0 or later. If the protect software is not Software R3.3.0 or later, do not revert.
Step 6 Click Revert. The Revert button activates the protect software load.
Step 7 Click Yes in the revert confirmation dialog box. The ONS 15327 reboots and loses the connection to CTC.
Step 8 Wait until the software upgrade finishes. This might 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 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-B60 Log into CTC" task as necessary.
The browser downloads the CTC applet for the standby software load.
Step 12 If needed, recreate the circuits recorded in Step 3. See "Create Circuits and VT Tunnels" for specific circuit creation procedures.
