Forcing and Releasing Lasers
Forcing and Releasing Lasers
This section describes how to force a channel-module laser to be permanently on and
how to release an already forced-on laser. This can be done for the client port as well as
for the network port.
CAUTION
Laser Radiation Hazard!
(1) Only Service Personnel are allowed to configure a network
laser/amplifier/switch to “Force On” mode.
(2) The “Forced On” mode is only permitted for testing and servicing
purposes.
(3) Setting a network laser/amplifier/switch to “Force On” mode
increases the hazard level of the device. The operating
organization is solely responsible for the safety of the end-to-end
system.
(4) Service Personnel must assure that the device is located in an
appropriate area which guarantees that the conditions for an FSP
3000R7 are potentially met up to Hazard Level 3B.
Requirements
• You must be logged on to the NE with an ADMIN privilege level account.
• To receive reliable Optical Power Received (OPR) values and valid PM records at
the network-Rx interface, a valid signal has to be applied to the client-Rx interface.
Otherwise, alarms/conditions will be reported, e.g. loss of clock, invalid or wrong
OPR values.
The following modules are affected by this requirement:
• WCA-PCN-2G5U
• WCA-PC-10G-V
• 2WCA-PCN-10G
• 4WCE-PCN-16GFC

Other transponder modules such as WCC-PCTN-10G, 2WCA-PCN-10G, or 2TWCC-
PCN-2G7U have to be configured so that their network-Tx interface will send an error
propagation code (EPC) or alternatively is mapped to the optical transport unit (OTU).
Step 1 Select .
Step 2 In the Navigation Tree, select
Shelf
>
Channel module slot
.
Step 3 In the Ports blade, select the relevant client or network channel (for example,
CH-1-1-NW) for which the laser needs to be “forced on”.
Step 4 To be able to force a laser on, set the Admin State to Maintenance.
Step 5 Select to save your setting.
The Force Laser On checkbox is now accessible.

Without inserted and supported SFP+ at the respective port, the network port will not
emit any light although the network laser is forced on.
