Configuration Example#5:
This configuration example includes a fully loaded chassis (OS9700 chassis) +
A PoE Power Shelf (OS9-IP-SHELF) with a total of 4 x 600watts PoE P/S (OS9-IPS-0600A):
Step#1: Calculate the heat dissipated in the main fully loaded chassis:
(One OS9700 chassis + the fan-tray) + 2 x OS9700-CMM + 8 x OS9-GNI-P24;
Total System Power (“load”): 80watts + 2 x 27watts + 8 x 54watts = 566watts
Total AC input power required is: 754.66 watts (566 watts / 75%)
754.66watts x 3.41214 BTU/hr. = 2,575.00 BTU/hr.
Total Heat Dissipation for the fully loaded chassis: 2,575 BTU/hr.
Step#2: Calculate the heat dissipated by the 4 x 600watts PoE P/S (OS9-IPS-0600A):
Total AC input power required per PoE P/S: 800 watts (600 watts / 75%)
Due to inefficiency of each PoE P/S 200watts (800watts – 600watts) is consumed per each PoE P/S:
4 x 200watts = 800watts total is consumed per a fully loaded Power Shelf
800watts x 3.41214BTU/hr. = 2,729.712 BTU/hr.
Total Heat Dissipation for the fully loaded Power Shelf: 2,730 BTU/hr.
Step#3: calculate the total heat dissipation:

Configuration Example#6:
This configuration example includes a OS9700-CB-A chassis + x NIs (as described) +
A PoE Power Shelf (OS9-IP-SHELF) with a total of 3 x 600watts PoE P/S (OS9-IPS-0600A):
Step#1: Calculate the heat dissipated in the main chassis:
(OS9700-CB-A: One OS9700 chassis + the fan-tray) + 1 x OS9700-CMM + 5 x OS9-GNI-P24 +
1 x OS9-GNI-U24 + 2 x OS9-GNI-C24;
Total Sys Pwr (“load”): 80watts + 1 x 27watts + 5 x 54watts + 1 x 55watts + 2 x 51watts = 534watts
Total AC input power required is: 712 watts (534watts / 75%)
712watts x 3.41214 BTU/hr. = 2,429.44 BTU/hr.
Total Heat Dissipation for the fully loaded chassis: 2,430 BTU/hr.
Step#2: Calculate the heat dissipated by the 3 x 600watts PoE P/S (3 x OS9-IPS-0600A):
The PoE IP Shelf (OS9-IP-SHELF) power consumption is: Negligible
Total AC input power required per PoE P/S: 800 watts (600 watts / 75%)
Due to inefficiency of each PoE P/S 200watts (800watts – 600watts) is consumed per each PoE P/S:
3 x 200watts = 600watts total is consumed per a fully loaded Power Shelf
600watts x 3.41214BTU/hr. = 2,047.28 BTU/hr.
Total Heat Dissipation for the fully loaded Power Shelf: 2,048 BTU/hr.
