battery backup time for the NTAK75
•
battery backup time for the NTAK76
Use the circuit-card power-consumption table and worksheets provided
below.
Procedure
1
Determine the circuit card configuration in each system cabinet.
Record the card codes against their cabinet slot numbers, on
“Worksheet Ga: System power consumption: Main cabinet” on
page 146 through “Worksheet Ge: System power consumption: fourth
expansion cabinet” on page 150.
2
For each circuit card, transfer the power consumption values from
“Worksheet G: System power consumption” on page 144 to the power-
consumption column on the corresponding
Worksheets Ga - Ge.
3
Calculate the total option 11C system power consumption on
“Worksheet Gf: Total Option 11C system power consumption” on
page 151.
4
If your system is AC-powered, go to “Worksheet H: Battery current and
AC line calculation for AC systems using NTAK75 and NTAK76” on
page 153. If your system is DC-powered, go to“Worksheet I: Battery
current calculation for customer-provided DC reserve power” on
page 154.
5
Transfer the P
out
(Main) and P
out
(Expan.) values from
Worksheet G to Worksheet H or I.
6
Calculate P
in
(Main), I
Batt
(Main), P
in
(Expan), and I
Batt
(Expan) as
shown on Worksheet H or I.
7
Calculate I
line
if required, as shown on Worksheet H.
8
Transfer the values calculated for I
Batt
(Main) and I
Batt
(Expan), onto
the NTAK75/QBL24A1 and the NTAK76 discharge time graphs.
9
Select the battery unit that provides the most appropriate backup time.
Note:
For customer-provided DC reserve power systems, use I
Batt
(Main) and I
Batt
(Expan) along with the battery manufacturer’s
specifications to determine battery requirements and backup times.
