Procedure 12-8.1: Upgrade or replace SYSCTL (LNW2) by replacing NVMs

- Overview

Use this procedure to replace an LNW2 by replacing NVMs.

Important!

You must have physical access to your shelf and controller.

- Required equipment

Refer to Required equipment in Procedure 12-8: Upgrade or replace SYSCTL (LNW2) circuit pack for a list of equipment required to perform this procedure.

- Before you begin

Prior to performing this procedure, complete Procedure 12-8: Upgrade or replace SYSCTL (LNW2) circuit pack.

Steps

Complete the following steps to replace an LNW2 by replacing NVMs.

 
1

Initiate a ten-second countdown (9, 8, 7, 6, 5, 4, 3, 2, 1, 0) in the IND display on the LNW2 SYSCTL by simultaneously depressing the ACO TEST and SEL buttons on the front of the LNW2 SYSCTL.

Important!

Removing the LNW2 without initiating the ten-second countdown may result in unexpected and undesirable protection switches, incorrect circuit fault indications, or incoming signal failure alarms. All SYSCTL functions are suspended during the countdown.

2

Remove the LNW2 SYSCTL circuit pack during the 10-second countdown. This LNW2 will be referred to as the “old” SYSCTL throughout this procedure.

Important!

While the SYSCTL circuit pack is removed, do NOT remove or replace any transmission circuit packs.

3

Physically remove the NVMs from your old LNW2 and set them aside.

4

Remove the NVMs from your new (replacement) LNW2 and set them aside.

5

Insert the NVMs that you removed from the old SYSCTL in Step 3 in the empty NVM sockets in your new (replacement) LNW2.

6

Important!

For software installation, ensure that two NVMs are present in the LNW2 SYSCTL. You should have installed the NVMs from your old SYSCTL in your new SYSCTL.

Seat the new LNW2 SYSCTL circuit pack equipped with the NVMs from the old SYSCTL and allow a few minutes for the pack to complete initialization.

Result:

The LNW2 SYSCTL exhibits the following visible cycles during initialization:

  1. The FAULT LED lights and remains lighted for approximately 15 seconds. After approximately 15 seconds, a flashing b appears in the IND display on the SYSCTL, indicating that a boot is in progress. The b continues flashing for approximately 60 seconds and then IND display is blank.

  2. The FAULT LED remains lighted for approximately another 20 seconds and then extinguishes.

  3. The ACTIVE LED lights and remains lighted.

  4. A flashing b appears again in the IND display on the SYSCTL, indicating that a boot is in progress. After approximately 30 seconds, the CR LED flashes 10 times and then extinguishes, and the b continues flashing for approximately another 30 seconds, and then IND display is blank.

  5. The ACTIVE LED remains lighted and the other LEDs return to their previous states; prior to the replacement.

  6. Continue with Step 7.

7

Proceed to Procedure 12-8.4: Verify proper software generic.
