Movaz Procedures (NETS notes)

Turning off an OSC laser

The fiber path from Laramie to Fort Collins is too long for a standard laser. This matters at the 1310 wavelength used by the Movaz OSC, but not at the 1500+ wavelengths used by data lambdas. Fixes for this problem exist (RAMAN amplifiers) didn't exist when we installed the circuit, so we've simply lived with no OSC from LAR to FORT.

Trouble is, the 1310 lasers can almost reach the distance, so the Movazes keep trying to make OSC between LAR and FORT work. This unstable OSC causes problems, so we decided to turn the OSC off completely - no OSC is better than a flaky OSC.

Turning off an OSC laser is a bit tricky...

Scott/Richard/Brad,

It seems that the SP at Longmont is hung. So, I suggest you send a technician to this site and reseat the SP if the SPs look normal (SP with green Status light on). When you do this, please make sure the card is firmly seated all the way to the back when re-inserting the SP. If not inserted firmly, it may affect the SPs performance.

Regarding the CSU-1 SP hung issue, it seems that even though the distance between both nodes is too long and OSC is down, the node was seeing some packets coming in frequently from the OSC channel. So, it is possible that this packets were making the SP to hang as it is trying to process them.

So, to avoid this to happen again, we suggest the following steps to turn off the OSC laser:

At CSU-1 and LARAMIE-1:

To be able to perform this steps, the technician needs to be connected to the craft interface port and logged in with root priviledges.

Step 1. After logging into the console, log into the shell by pressing Control, Shift, and "-" simultaneously.

Step 2. You will receive a prompt "shell login:". Type "root" and press enter.

Step 3. You will then receive another prompt, "shell password:". Type "root" and press enter.

Step 4. Follow step 4.a or 4.b to turn the OSC Tx laser on or off, respectively.

Step 4.a To turn on the OSC Tx, type the following line, replacing "<slot>" with the slot number the OLD occupies:

genMsg <slot>,6,0x44,0,1,"01"
The response should be very simlar to:
<genMsgRply>7E000400000DFF7406440001004599</genMsgRply>
value = 15993896 = 0xf40c28 = cout

Step 4.b To turn off the OSC Tx, type the following line, replacing "<;slot>" with the slot number the OLD occupies:

genMsg <;slot>,6,0x44,0,1,"00"
The response should be very simlar to:
<genMsgRply>7E000400000DFF7406440001004599</genMsgRply>
value = 15993896 = 0xf40c28 = cout

Step 5. Logout of the shell by typing "exit" at the prompt and pressing enter.

Step 6. At the prompt, enter the following:

show pm port <slot>-3 opt

Step 7. That command should return with the PM table. An example is shown below. The line indicating the OSC Tx level is bold. If the OSC Tx is "ON" the Value column will contain a numeric value. If the OSC Tx is "OFF", the Value column will contain a "-" and the OOR column will contain "lo".
