Coriant 8665 - Power Input Specification Details; Power Consumption and Heat Dissipation; PIM and Unit Slot Specifications

6 Technical Specifications
Check that the operational temperature range of the SFP/SFP+/XFP module is suitable for
the installation environment. Note that the temperature of the SFP/SFP+/XFP case will be
approximately 15 degrees higher than ambient temperature. For more information on the
allowed SFP/SFP+/XFP case temperature range see chapter Pluggable Transceivers in 8600
Smart Routers H ard ware Installation Guide.
Power input specification 8665 Smart Router equipped with PIMs:
• -48 Vdc nominal input voltage
• -40 Vdc...-60 Vdc absolute input voltage range
• 85A maximum current
4
• Fuses inside PIM 2* T60A, strip fuse, bolt down
External circuit breakers shall be used on the battery side of the
power cable for PIM. See recommendations for external circuit
breakers in 8600 Smart Routers Hardware Installation Guide.
Power consumption Maximum power capacity of
• 8665 Smart Router subrack e quipped with 8665 Smart
Router DC48 power input modules can be used with power
consumptions of up to 3400 W. With LU -1 and SU-1 the
maximum power that can be used is maximum 1.7kW
The typical and maximum power consumption values for all cards
and modules can be seen in the corresponding chapters of this
manual.
See more information in chapter 1.3 8665 Smart Router Power
Consumption.
Heat dissipation In practice, all electrical power turns into heat in 8600 Smart
Routers. Thus, when calculating the power dissipation of the NE,
the same figure represents the heat dissipation in Watts.
Depending on the configuration of the system the equipment area
heat release may exceed the limit specified in [GR-63-CORE]
(995 [W/m2]). If this interferes with t he cooling capacity of the
installation facility, additional equipment for room cooling may be
required.

Max input current: 85 A.
Power feeding protection (redundancy) is achieved with two PIMs
in 8665 Smart Router R2 subrack.
Coriant recommends that 2 PIMs should always be used.
Unit Slots 6 slots for line units, 2 slots for switch units.
