Clear the HITEMP Alarm
Step 1 View the temperature displayed on the ONS 15454 LCD front panel (Figure 2-2).
Figure 2-2 Shelf LCD Panel
Step 2
Verify that the environmental temperature of the room is not abnormally high.
Step 3 If the room temperature is not abnormal, physically ensure that nothing prevents the fan-tray assembly
from passing air through the ONS 15454 shelf.
Step 4 If airflow is not blocked, physically ensure that blank faceplates fill the ONS 15454 shelf empty slots.
Blank faceplates help airflow.
Step 5 If faceplates fill the empty slots, determine whether the air filter needs replacement. Refer to the
“Inspect, Clean, and Replace the Reusable Air Filter” procedure on page 2-278.
Step 6 If the fan does not run or the alarm persists, complete the “Replace the Fan-Tray Assembly” procedure
on page 2-280.
Note The fan should run immediately when correctly inserted.
Step 7 If the replacement fan-tray assembly does not operate correctly, log into the Technical Support Website
at http://www.cisco.com/techsupport for more information or call Cisco TAC to report a
Service-Affecting (SA) problem 1 800 553-2447 if it applies to the NE, or a
Non-Service-Affecting (NSA) problem if it applies to equipment.
2.7.164 HI-TXPOWER
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, OCN
DWDM Logical Objects: 2R, ESCON, FC, GE, ISC, PPM, TRUNK
The Equipment High Transmit Power alarm is an indicator on the TXP_MR_E, TXP_MR_10G,
TXP_MR_2.5G, TXPP_MR_2.5G, MXP_2.5G_10G, MRC-12, MRC-4, or OC192-XFP card
transmitted optical signal power. HI-TXPOWER occurs when the measured optical power of the
transmitted signal exceeds the threshold.
Note For more information about provisioning MXP or TXP PPMs, refer to the “Provision Transponders and
Muxponders” 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.
