Serial Console Port on Installed Management Module
To configure the module using the serial port, attach a DB-9 serial (RS-232) equipped
computer with terminal emulation software such as Procomm or Putty to the serial port
on the module using the included serial adapter. Some computers do not come with
DB-9 serial port connectors and may require a USB-to-serial port adapter.
The port is a standard RS-232 asynchronous serial interface. The serial ports is
configured for 57,600bps, 1 stop, 8 data, parity none.
Access to the configuration options for the 1-Module Redundant Power Chassis can be
accomplished by selecting option
1
from the
Management Options
screen. From the
Chassis View
screen, select the 1-Module Redundant Chassis option
2
. The chassis
configuration options will be displayed.
The
Module Screen
(DIP-switch control shown) provides general information concerning
the configuration and status of the module. The screen displays the model and serial
numbers, hardware and software revisions, as well as the condition of the LEDs, Alarm
Indicators and DIP-switches. The DIP-switches
1 - 4
correspond with the physical
switches on the back of the chassis. These switches can be changed from the
Module
Screen
by selecting the appropriate switch number. DIP-switches
9 - 15
can only by
configured from the
Module Screen
options. Select the appropriate option to change
the DIP-switch setting.
The

Applications
Battery Backup with Alarms
When the chassis is used with a battery backup power system, the alarm contact
sensor can be used to report conditions associated with the backup power system. In
this configuration, the chassis can provide a managed power fault detection system.
The figure below depicts an APC PowerShield battery backup unit connected to
the chassis using the 8-pin terminal connector on the back of the chassis, In this
configuration, the chassis is monitoring the power conditions of the APC units and will
report any failures to the network management system.
