Power Supplies for the Cisco ASR 1013 Router
•
Thermal Shutdown—The +24 VDC power supply will shut down to protect its components due to
excessive internal temperature. The +24 VDC power supply then automatically restarts if the
internal temperature returns to a safe operating level.
Power Supplies for the Cisco ASR 1013 Router
Note
The information in this section applies to the ASR1013/06-PWR-DC and ASR1013/06-PWR-AC power
supplies. These power supplies are supported by both the Cisco ASR 1013 Router and the Cisco ASR
1006 Router. However, the power zones mentioned in this section are supported only on the Cisco ASR
1013 Router.
The Cisco ASR 1013 Router can support up to 1600 W output and operates between 180 VAC and 260
VAC. The 1600 W power supply module consists of either an AC or –48 VDC input and 1600 watt output
closed frame power supply with two DC voltage outputs: +12 V and +3.3 V can be used as a single
supply, dual, triple, or quadruple hot pluggable system.
Note
The Cisco ASR 1013 router power 12 V is not bussed between the two power zones but the +3.3
V is bussed between them.
The Cisco ASR 1013 system has two power zones, each powered by two power supplies in a redundant
configuration. Three power voltages are provided by the dual 1+1 configured power supplies, which are
12V_A, 12V_B, and 3.3V_BACKPLANE. The12V_A AND 121V_B are distributed to provide power
to one half of the chassis each. A single (non-redundant) or a dual (1 + 1 redundant) supply configuration
is able to support loads up to 1600 W on the 12 V and 10 W on the 3.3 V output.
Each power supply module contains three internal fan modules and provides the forced air cooling for
the chassis. These power supply modules contain a monitor circuit to determine the status of fan speed
and operation along with LED status indicating fan errors.
The system temperature operation is 0 to 40C normal and –5C to +55C.
AC System—AC power input is an IEC 320-type power inlet, 20 A service connector. The switch
does not disconnect the AC line; but enables the signal to the power supply. The AC cord disconnects
the power supply from the AC source. The unit is secured with four captive fasteners mounted on
the faceplate (see
Figure 2-15
).
The AC power supply input range operates within specification from 180 VAC to 264 VAC.
•
–48 VDC System—Two-position terminal block-style connector, with labeled connections for -
(–48/60 V input) and + (–48/60 V Return). The –48 VDC input side contains a front panel with
provisions for mounting screw, built in handle to extract the power supply, three status LEDs, and
fans for power supply and system cooling.
The DC input range is –40.5 to –72 VDC.

specifications.
