Temperature Management
Grounding the Chassis
The switch has two threaded holes for grounding screws located on the back of the chassis. These holes
use 10-32 screws and are approximately one inch apart. These holes are surrounded by a small paint-free
rectangular area, which provides metal-to-metal contact for a ground connection.
Use this connector to supplement the ground provided by the AC power cord. To do so, install a Panduit
Grounding Lug (type LCD8-10A-L) using 8AWG copper conductors to the paint-free rectangular area.
The crimping tool required is the Panduit CT-940CH.
Temperature Management
The operating temperature of your switch is an important factor in its overall operability. In order to avoid
a temperature-related system failure, your switch must always run at an operating temperature given in the
specificatons table.
To avoid chassis over-temperature conditions, follow these important guidelines:
1
Be sure that your switch is installed in a well-ventilated environment. To ensure adequate airflow,
allow at least six inches of clearance at the front and back of the chassis. In addition, leave at least two
inches of clearance at the left and right sides.
2
If your switch chassis is not fully populated with NI modules, be sure that blank cover panels are
installed at empty slot positions at all times. Blank cover panels help regulate airflow and thus regulate the
overall operating temperature in the switch. Refer to
Monitoring Chassis Temperature Status. To check the switch's current temperature status, use the
show temperature
command. For example:
-> show temperature
Hardware Board Temperature (deg C)
Hardware Cpu Temperature (deg C)
Temperature Upper Threshold Range (deg C) = 30 to 80,
Temperature Upper Threshold (deg C)
Temperature Range
Temperature Danger Threshold (deg C)

chapter in the OmniSwitch CLI Reference Guide.
