Chapter 1 Cisco ASR 1000 Series Routers Hardware Overview
Functional Overview
•
The Cisco ASR 1002 Router supports the integrated Cisco ASR1000-RP1, which is a combined
route processor and carrier card that are not field-replaceable units. The Cisco ASR1000-ESP5 or
ASR1000-ESP10 are field-replaceable units.
•
The Cisco ASR 1002-F Router supports an integrated route processor Cisco ASR1002-RP1 and an
integrated embedded services processor Cisco ASR1000-ESP-F, which are not field-replaceable.
The Cisco ASR1002-SIP10-F module is not removable; but the one half-height SPA is a
field-replaceable unit.
•
The Cisco ASR 1002-X Router supports an integrated route processor (Cisco ASR1002-RP2) and
an integrated embedded services processor. Both these components are not field-replaceable. The
router has a built-in 6x1GE SPA that occupies the SPA Bay 0. In addition, there are three half-height
SPA bays for field-replaceable SPAs.
The following is a functional description of OIR for background information only; for specific
procedures for installing and replacing a shared port adapter in Cisco ASR 1000 Series Routers, refer to
the online configuration note for each shared port adapter.
When you remove or insert a shared port adapter in a Cisco ASR 1000 Series Router, the Control
Processor notifies the Cisco ASR1000-RP1, which in turn notifies the forwarding engine control
processor (FECP), and then performs the following steps:
•
Rapidly scans the midplane for configuration changes.
•
Initializes all newly inserted shared port adapters, noting any removed interfaces and placing them
in the administratively shutdown state.
•
Brings all previously configured interfaces on the shared port adapter back to the state they were in
when they were removed. Any newly inserted interfaces are put in the administratively shutdown
state, as if they were present (but not configured) at boot time. If a similar shared port adapter type
is reinserted into a slot, its ports are configured and brought online up to the port count of the
original SPA.
Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions allow you to maintain normal system operation by
identifying and resolving adverse conditions prior to loss of operation.
Caution
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Over temperature
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.
Environmental Monitoring
The environmental monitoring functions use sensors to monitor the temperature of the cooling air as it
moves through the chassis.
The local power supplies provide the ability to monitor:
•
Input and output voltage
•
Output current
•
Outlet temperature
