DLP-A199 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

None



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 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 might have collected on the filter and proceed to Step 9. Figure 17-1 illustrates a reusable fan-tray air filter in an external filter bracket.

Step 3 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 4.

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 4 Remove the front door (optional). If you do not want to remove the door or it is already removed, 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 17-1 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 (25.4 mm) 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 might 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 reinsert the fan-tray assembly. Then, vacuum the dirty air filter or wash it 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 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.


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 below 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, 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).


DLP-A200 Inspect and Replace the Disposable Air Filter

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.

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 inch (25.4 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 (Figure 17-2).


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.

Figure 17-2 Inserting or Removing the Fan-Tray Assembly (Front Door Removed)

Step 7 Gently remove the air filter from the shelf assembly (Figure 17-3). Be careful not to dislodge any dust that might have collected on the filter.

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

Step 9 If the air filter shows a heavy concentration of dirt and dust, replace it with a new filter by sliding the new filter into the bottom of the shelf assembly. Make sure that the front of the filter is flush with the front of the shelf assembly and that the air flow indicators on the filter point upwards.

Figure 17-3 Inserting or Removing a Disposable Fan-Tray Air Filter (Front Door Removed)

Step 10 Slide the fan-tray assembly into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.

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 replace the door, also reattach the ground strap.

Step 14 Close and lock the door.

Note The following parameters are not backed up and restored: node name, IP address, subnet 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.



Note For information on restoring the ML-Series card, refer to the Cisco ONS 15454 SONET/SDH ML-Series Multilayer Ethernet Card Software Feature and Configuration Guide.



Caution E1000-2 cards lose traffic for approximately 90 seconds when an ONS 15454 database is restored. Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm appears and clears during this period.


Caution If you are restoring the database on multiple nodes, wait approximately one minute after the TCC2 reboot has completed on each node before proceeding to the next node.


Step 1 Complete the "DLP-A60 Log into CTC" task at the node where you are restoring the database. If you are already logged in, continue with Step 2.

Step 2 Ensure that no ring or span (four-fiber only) switch events are present; for example, ring-switch east or west, and span-switch east or west. In network view, click the Conditions tab and click Retrieve to view a list of conditions.

Step 3 If switch events need to be cleared, in node view click the Maintenance > BLSR tabs and view the West Switch and East Switch columns.

Step 12 If you cleared a switch in Step 3, reapply the switch as needed.

Stop. You have completed this procedure.


NTP-A163 Restore the Node to Factory Configuration

Purpose

This procedure clears the TCC2 database and restores customer or factory defaults by uploading the most recent software package and a blank database. This process is performed using the RE-INIT.jar utility, also called the reinitialization (reinit) tool.

Tools/Equipment

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

Prerequisite Procedures

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 use the Search Path field instead of the Package and Database fields. You may accidentally copy an incorrect database if multiple databases are kept in the specified directory.


Caution Restoring a node to the factory configuration deletes all cross-connects on the node.


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 Restoring a node to factory configuration on a Windows or Unix workstation should only be carried out on a standby TCC2 card.


Caution Cisco recommends that you take care to save the node database to safe location if you will not be restoring the node using the database provided on the software CD.


Note The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, subnet 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-A36 Install the TCC2 Cards" task.

Step 2 If you are using Microsoft Windows, complete the "DLP-A244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)" task.

Step 3 If you are using UNIX, complete the "DLP-A245 Use the Reinitialization Tool to Clear the Database and Upload Software (UNIX)" task.

Stop. You have completed this procedure.

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



Caution 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.


Note Reverting to a 2.2.1 or later load switches to the older software load and its database without affecting traffic or DCC connectivity. This feature requires dual TCC2 cards and CTC Software R 2.2.1 or later as the protect version.



Note Circuits created and provisioning performed after a software load is activated (upgraded to a later 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 (for example, R2.2.2 to R2.2.1), because maintenance releases use the same database.



Step 1 Complete the "DLP-A60 Log into CTC" task to log into 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 of the node view window.


Note To find the IP address you can also click the Provisioning > Network > General tabs.


Step 3 If you are reverting to a previous software release (not a maintenance release), record any new circuits created since the previous software upgrade because these circuits have to be manually recreated after the software reversion if you still need to have them.

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.


Note The TCC2 card is compatible with Software R4.0 and later.


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

Step 7 Click Yes in the revert confirmation dialog box. The ONS 15454 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 Completely close the browser.

Step 11 Restart the browser and log back into the node using the IP address recorded in Step 2.

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

Step 12 If needed, recreate the circuits recorded in Step 3. See "Create Circuits and VT Tunnels" for specific circuit creation procedures.

Stop. You have completed this procedure.

Table 17-1 ONS 15454 Timing Report 

Item
Description
Option
Option Description

Clock

Indicates the timing clock. The report section that follows applies to the timing clock indicated.

NE

The node timing clock.

BITS-1 Out

The BITS-1 Out timing clock.

BITS-2 Out

The BITS-2 Out timing clock.

Status

Indicates the status of the timing clock.

INIT_STATE

The timing reference has not been provisioned. For an NE reference, this status appears just before the first provisioning messages when the TCC2 is booting. Timing is provisioned to the internal clock of the node.

HOLDOVER_STATE

The clock was locked onto a valid timing reference for more than 140 seconds when a failure occurred. Holdover state timing is a computation based on timing during normal state combined with the node's internal clock. The node holds onto this frequency until the valid reference is restored. This status appears for NE references only.

FREERUN_STATE

The node is running off its internal clock without any modification except the calibrated value to bring timing to 0 PPM. Freerun state can occur when a Force switch to the Internal clock is initiated, all references fail without the 140 seconds of holdover data, or only Internal timing references are defined. This status appears for NE references only.

NO_SYNC_STATE

A synchronization timing reference is not defined. BITS-1 Out or BITS-2 Out default to this status until an OC-N card is defined as its reference on the Provisioning > Timing tab. This status appears for external references only.

NE_SYNCH_STATE

BITS-1 Out and BITS-2 Out use the same timing source as the NE. This is displayed when NE Reference is selected for BITS-1 Out and BITS-2 Out Reference List on the Provisioning > Timing tab.

NORMAL_STATE

The timing reference is locked onto one of its provisioned references. The reference cannot be Internal or no sync state.

FAST_START_STATE

The node has switched references, but the reference is too far away to reach normal state within an acceptable amount of time. Fast Start is a fast acquisition mode to allow the node to quickly acquire the reference. After it achieves this goal, the node progresses to the normal state.

FAST_START_FAILED_STATE

A timing reference is too far away to reach in normal state. The fast start state could not acquire sufficient timing information within the allowable amount of time.

Status Changed At

Date and time of the last status change.

Switch Type

Type of switch.

AUTOMATIC

The timing switch was system-generated.

Manual

The timing switch was a user-initiated Manual switch.

Force

The timing switch was user-initiated Force switch.

Reference

Indicates the timing reference.

Three timing references are available on the Provisioning > Timing tab.

Selected

Indicates whether the reference is selected.

Selected references are indicated with an X.

Facility

Indicates the timing facility provisioned for the reference on the Provisioning > Timing tab.

BITS-1

The timing facility is a BITS clock attached to the node's BITS-1 pins.

BITS-2

The timing facility is a BITS clock attached to the node's BITS-2 pins.

OC-N card with port #

If the node is set to line timing, the OC-N card and port provisioned as the timing reference.

Internal clock

The node is using its internal clock.

State

Indicates the timing reference state.

IS

The timing reference is in service.

OOS

The timing reference is out of service.

Condition

Indicates the timing reference state.

OKAY

The reference is valid to use as a timing reference.

OOB

Out of bounds; the reference is not valid and cannot be used as a timing reference, for example, a BITS clock is disconnected.

Condition Changed

Indicates the date and time of the last status change in MM/DD/YY HH:MM:SS format.

SSM

Indicates whether SSM is enabled for the timing reference.

Enabled

SSM is enabled.

Disabled

SSM is not enabled.

SSM Quality

Indicates the SSM timing quality.

8 to 10 SSM quality messages might be displayed.

For a list of SSM message sets, see the "Security and Timing" chapter in the Cisco ONS 15454 Reference Manual.

SSM Changed

Indicates the date and time of the last SSM status change in MM/DD/YY HH:MM:SS format.
