Procedure 6-3: Replace DS1 (LNW6/LNW7/LNW8/LNW801) circuit pack
Overview
Use this procedure to replace the following circuit packs:
Important!
The LNW8 and LNW801 circuit packs have common functionality and are directly interchangeable. The LNW8 and LNW801 circuit packs can occupy the same Function/Growth group together.
The system does not support mixing standard density (LNW6 and LNW7) in the same function group.
Important!
The high-density LNW8 and LNW801 56DS1/E1 circuit packs are only compatible with the Alcatel-Lucent 1665 DMX High Capacity Shelf (DMX-HC-20A, DMX-HC-30A, or DMX-HC-30A-CE Shelf Type). The standard Alcatel-Lucent 1665 DMX Shelf does not support the high-density LNW8 and LNW801 56DS1/E1 circuit packs. If a high-density LNW8 or LNW801 56DS1/E1 circuit pack is installed in the standard Alcatel-Lucent 1665 DMX Shelf, the system will not recognize the circuit pack as an allowable type.
To determine the shelf type, select View → Equipment, highlight Shelf, and click Select to obtain the shelf details.
It is assumed that the DS1 cables have already been installed. Refer to the Alcatel-Lucent 1665 Data Multiplexer (DMX) Installation Manual, 365-372-304 for cabling information.
Important!
If both the original circuit pack and the replacement circuit pack fail when no other transmission circuit packs are installed in the shelf, replace the SYSCTL circuit pack. Refer to Procedure 6-10: Upgrade or replace SYSCTL (LNW2) circuit pack.
Before you begin
Prior to performing this procedure:
-
Refer to Required equipment in this chapter.
-
Refer to Electrostatic discharge information in Chapter 1, Safety.
-
Ensure that the appropriate DS1 circuit pack is available for replacement.
Steps
Complete the following steps to replace a DS1 circuit pack.
1 |
From the System View menu, select View → Protection to view the current protection on the circuit pack you are replacing. | ||||||
2 |
Does 1+1 Equip appear next to the DS1 circuit pack that you wish to replace?
| ||||||
3 |
Highlight the Function Unit (for example: 1+1 Equip Fn-d represents Function Unit D) containing the circuit pack you wish to replace and click Select. | ||||||
4 |
Does the Circuit Pack State for the circuit pack that you wish to replace read In Service?
| ||||||
5 |
From the System View menu, select Fault → Protection Switch. | ||||||
6 |
Highlight the Function Group that contains the circuit pack that you are replacing and click Select. Result: On the right side of the Switch Protection window, the Switch Type: pull-down menu appears. | ||||||
7 |
From the Switch Type: pull-down menu, select Forced and click Apply. Result: A confirmation window appears: "Execution of provision may affect the NE service. Do you want to execute this command?" | ||||||
8 |
On the confirmation window, click Yes to ensure that service switches to the other circuit pack in the Function Group. Click Close on the Switch Protection window. | ||||||
9 |
To verify that the switch has occurred:
| ||||||
10 |
Remove the DS1 circuit pack by grasping the inner edge of the locking-levers, and applying a constant pressure, pull the levers forward and remove the circuit pack. | ||||||
11 |
Seat the replacement DS1 circuit pack in the vacated Function Unit slot by applying steady pressure to both faceplate latches. Result: FAULT LED on the DS1 circuit pack lights for approximately 20 seconds, then goes off. ACTIVE LED remains off. However, if your circuit pack was in-service and unprotected (refer to Step 2), then the FAULT LED on your replacement pack flashes until the signal is verified to be free of errors. (Firmware updates may take place that add additional wait time.) Select View → Refresh System View and the circuit pack appears in the WaveStar® CIT System View indicating successful installation. | ||||||
12 |
From the System View menu, select Fault → Protection Switch. | ||||||
13 |
Highlight the Function Group that you force-switched and click Select. Result: On the right side of the Switch Protection window, the Switch Type: pull-down menu appears. | ||||||
14 |
From the Switch Type: pull-down menu, select Reset and click Apply. Result: A confirmation window appears: "Execution of provision may affect the NE service. Do you want to execute this command?" | ||||||
15 |
On the confirmation window, click Yes to ensure that service switches to the other circuit pack in the Function Group. Click Close on the Switch Protection window. | ||||||
16 |
To verify that the forced switch is removed:
| ||||||
17 |
Do you wish to restore the original Active/Standby states?
| ||||||
18 |
From the System View menu, select Fault → Protection Switch. | ||||||
19 |
Highlight the Function Group and click Select. Result: On the right side of the Switch Protection window, the Switch Type: pull-down menu appears. | ||||||
20 |
From the Switch Type: pull-down menu, select Manual and click Apply. Result: A confirmation window appears: "Execution of provision may affect the NE service. Do you want to execute this command?" | ||||||
21 |
On the confirmation window, click Yes to ensure that service switches to the other circuit pack in the Function Group. Click Close on the Switch Protection window. | ||||||
22 |
To verify that the switch has occurred:
| ||||||
23 |
From the System View menu, click the Alarm List button to obtain an NE Alarm List. Verify that no alarms are present for the installed circuit pack. If required, refer to the appropriate procedure to clear any alarms. | ||||||
24 |
From the System View menu, use View → Equipment to access the circuit pack/port parameters for the circuit pack just installed and verify that the parameters are intact. If required, refer to the appropriate procedure in the Alcatel-Lucent 1665 Data Multiplexer (DMX) User Operations Guide, 365-372-301 to change any circuit pack/port parameters. End of steps |
