2.7.161 HI-LASERTEMP
The Equipment High Laser Optical Transceiver Temperature alarm applies to the TXP and MXP cards.
HI-LASERTEMP occurs when the internally measured transceiver temperature exceeds the card setting
by 35.6 degrees F (2 degrees C). A laser temperature change affects the transmitted wavelength.
When the TXP or MXP card raises this alarm, the laser is automatically shut off. The
alarm on page 2-164
at the near end.
Note For more information about provisioning MXP or TXP PPMs, refer to the "Provision Transponder and
Muxponder Cards" chapter of the Cisco ONS 15454 DWDM Procedure Guide. For more information
about the cards themselves, refer to the Cisco ONS 15454 DWDM Reference Manual.
Clear the HI-LASERTEMP Alarm
In node view, double-click the TXP or MXP card to open the card view.
Step 1
Click the Performance > Optics PM > Current Values tabs.
Step 2
Verify the card laser temperature levels. Maximum, minimum, and average laser temperatures are shown
Step 3
in the Current column entries in the Laser Temp rows.

2.7.162 HI-RXPOWER
The Equipment High Receive Power alarm is an indicator of the optical signal power that is transmitted
to the TXP_MR_10G, TXP_MR_2.5G, TXPP_MR_2.5G, TXP_MR_10E, MXP_2.5G_10G, MRC-12,
MRC-4, or OC192-XFP card. HI-RXPOWER occurs when the measured optical power of the received
signal exceeds the threshold. The threshold value is user-provisionable.
For more information about MXP or TXP cards, refer to the Cisco ONS 15454 DWDM Reference
