4 CPS Installer/User Guide
Extensive command set
The CPS offers a wide range of commands that allow administrators to
easily configure, control and display information about the CPS operating
environment, including its ports, user accounts and active sessions. The user
interface also offers descriptive error message data and built-in command help
information. On-board Trivial File Transfer Protocol (TFTP) support allows
administrators to upload new functionality to CPS units in the field.
Port history
Each CPS port has a buffer that holds the most recent 64K bytes of online and
offline serial data. A separate history command mode lets you navigate within
a port’s current history file and conduct tailored searches.
Safety Precautions
To avoid potential device problems when using Avocent products, if the building
has 3-phase AC power, ensure that a computer and its monitor (if used) are on
the same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment,
please observe the following precautions:
• Do not use a 2-wire extension cord in any Avocent product confi guration.
• Test AC outlets at the computer and monitor (if used) for proper polarity
and grounding.
• Use only with grounded outlets at both the computer and monitor. When
using a backup Uninterruptible Power Supply (UPS), power the computer,
the monitor and the CPS unit off the supply.
NOTE: The AC inlet is the main disconnect.
Rack mount safety considerations
• Elevated Ambient Temperature: If installed in a closed rack assembly, the
operation temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient temperature
of the unit.
• Reduced Airfl ow: Installation of the equipment in a rack should be such
that the amount of airfl ow required for safe operation of the equipment is
not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven
mechanical loading.
