Shelf Voltage and Temperature
The temperature that the TNC, TNCE, TSC, or TSCE sensors measure appear on the LCD screen in the ONS
15454 M6 chassis.
Note
The input voltages and temperature of the ONS 15454 M6 chassis are displayed in the

pane in CTC. The voltage supplied to the shelf (in millivolts)
is displayed in the Voltage area of the Voltage/Temperature pane. The temperature of the shelf (in degree
Celsius) is displayed in the Temperature area of the pane.
The Voltage/Temperature pane retrieves the following values for the ONS 15454 M6 chassis:
• Voltage A—Voltage of the shelf that corresponds to power supply A, in millivolts.
• Voltage B—Voltage of the shelf that corresponds to power supply B, in millivolts.
• Chassis Temperature—Temperature of the shelf, in degrees Celsius.
In a multishelf configuration, the voltage and temperature of each shelf is displayed in the

Cooling Profile
The cooling profile feature allows you to control the speed of the fans in the ONS 15454 M6 shelf depending
on the I/O cards used.
CTC allows you to choose a cooling profile for ONS 15454 M6 shelf. You can change the cooling profile in

pane in CTC. The supported cooling profile
values are Low, Medium, and High. The default cooling profile value is High. You can change the cooling
profile depending on the cards used in the shelf.
If there are multiple cards in the shelf, you must choose the cooling profile of the card that requires the highest
cooling profile. For example, if the shelf has two cards with low cooling profile, three cards with medium
cooling profile, and one card with high cooling profile, you must choose a high cooling profile for the shelf.
The wrong cooling profile chosen for the shelf might harm the cards present in the shelf.
Caution
If a wrong cooling profile is chosen for the shelf, the COOL-MISM condition is raised on the shelf. For more
information on the alarm, see the “COOL-MISM” alarm in Chapter 2, Alarm Troubleshooting of
Cisco ONS
15454 DWDM Troubleshooting Guide
.
The following table shows the cards that require high, medium, and low cooling profile.
