Table 1-3: Power For Modules (With Probes) - Tektronix DAS NT Option 04 User Manual

Getting Started

If the intended installation site is susceptible to dropped cycles in the power
source, it is strongly recommended that a line-conditioning device be installed to
help prevent dropped cycles. The line-conditioning device should be specified to
handle line currents being drawn by the mainframe; for line currents, refer to
Mainframe Power Requirements on page 1–8.
Module Power Requirements. Different combinations of modules requires that
different amounts of power be supplied by the Master mainframe or Expansion
mainframe. Some combinations may cause the line current to exceed the limits
of the power cord and power supply being used.
To determine which power cord/supply is required, check the terminal display
during power-on for a message describing the total wattage for the modules
currently installed in each attached mainframe. (Note: This power-on message is
erased after the Menu Selection overlay displays.) Compare the total card
wattage requirements (listed in Table 1–3) with the available mainframe power
listed in Tables 1–1 and 1–2. If the installed modules require more power than is
available from your current power cord/supply, you must upgrade the mainframe
to meet those requirements.
NOTE. If you changed the configuration of cards in the mainframe since the last
power-down, verify that the current power cord/supply supports the new
configuration. If you plan to add other modules to your system later, check the
power values in Tables 1–1, 1–2, and 1–3 to ensure that the total wattage
required by the new configuration can be supplied by your current mainframe
power cord/supply.
Table 1–3 lists the power consumed for each module. This table can also be used
when calculating the amount of power required for your specific configurations.
For example, assume a mainframe contains the following modules: one 92A16,
two 92A16Es, one 92S16, and one 92S32. The total power required equals:
107 W (A16) + 166 W (A16Es) + 78 W (S16) + 79 W (S32), or 430 watts total.
This value, when compared with the power cord options in Tables 1–1 and 1–2,
rules out the use of the standard 12 A power cord which is only able to deliver
up to 400 watts. The next-highest power cord option must be used; this is the
Option 1A power cord that supplies up to 500 watts to the card cage.
