Load Ramping And Shedding - Tripp-Lite SNMPWEBCARD Guia Del Usuario

5. Load Ramping and Shedding

Click the "Settings" menu button and the "Device" submenu button
to display the Settings > Device page. If your device supports load
ramping and shedding, the "Ramping" tab and/or "Shedding" tab
(Figure 5-1) will be available.
The "Ramping" and "Shedding" tabs each contain a table of the
load segments available for your device. Each load segment has
a "Description" field, an "Action" field and a "Delay" field. The
"Description" field allows you to enter a note about the equipment
connected to the load segment. The "Action" field allows you to
configure the load ramping or shedding behavior by choosing from
the possible actions listed in the drop-down menu. The "Delay" field
allows you to enter the delay (in seconds) before the specified action is
performed. After entering the desired values, click the "Save Changes"
button to make the values active. Ramping sequences are applied when
AC input power is switched on. Shedding sequences are applied when
AC input power is lost, increasing the battery backup runtime available
for supported equipment. You can disable load shedding by setting all
actions to "Remain On." You can disable load ramping by setting all
actions to "Remain Off."
Load ramping and load shedding require a Tripp Lite UPS system or
PDU with switchable load banks (banks of one or more outlets that
can be switched on and off remotely, independent of other outlets).
A device that has switchable load banks can be classified as an
autonomous device or a non-autonomous device, which determines its
load ramping and load shedding characteristics (Figure 5-2).
Autonomous Device
Non-Autonomous Device
An autonomous device can execute stored load shedding and load
ramping configurations independent of an SNMPWEBCARD
or PowerAlert. Configuration of an autonomous UPS system
requires PowerAlert or an SNMPWEBCARD (disconnect the
SNMPWEBCARD network cable before attempting to use an
autonomous UPS system's RS-232 serial port). Configuration of an
autonomous PDU requires an SNMPWEBCARD (the card is pre-
installed in "NET" models). Figure 5-3 lists autonomous devices that
are currently available.
Non-autonomous devices require an SNMPWEBCARD for
configuration and execution of a custom load shedding sequence. Non-
autonomous devices do not support custom load ramping. UPS systems
that have switchable load banks are non-autonomous devices unless
they are listed in Figure 5-3.
Note: Load ramping and shedding can also be configured through
the telnet console. (Select the first menu option "1- Devices" from the
Main Menu, then select the first device from the Device List menu, then
select the third menu option "3- Settings". From the Settings menu,
select the second menu option "1- Device". From the Device Settings
menu, select the second menu option "2- Shedding" for shedding
configuration or the third menu option "3- Ramping" for ramping
configuration.)
