Chapter 6 Cisco ASR 1002 Router Overview and Installation
Cisco ASR 1002 Router Description
Internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. The fans are located at the rear of the chassis. A two-hole grounding lug is located on the side of the chassis. Two power supplies, either two AC power supplies or two DC power supplies are accessed from the rear of the router.
Caution Use only AC power supplies or DC power supplies in the Cisco ASR 1002 Router. Do not mix power supply types.
Cisco ASR 1002 Router Components
The Cisco ASR 1002 Router system is derived from the architecture of the other Cisco ASR 1000 Series routers. The three main subassemblies of any Cisco ASR 1000 Series Routers are all supported in the Cisco ASR 1002 Router, which is the:
•Cisco embedded ASR1000-RP1 and Cisco embedded ASR1000-SIP10 (not field upgradable)
•Cisco ASR1000-ESP5 and Cisco ASR1000-ESP10 embedded services processors are field-replaceable units (FRU)
•AC or DC power supplies which are field-replaceable units
Cisco Embedded ASR1000-RP1 for Cisco ASR 1002 Router Description
The Cisco ASR 1000 Series route processor (embedded for the Cisco ASR 1002 Router) is the central control processor and runs the network operating system.
The Cisco embedded ASR1000-RP1 supports management interfaces such as the Ethernet network management port and console and auxiliary serial ports. It has LED status indicators, an RJ-45 plug for a BITS timing reference and one USB port which can be used with smart cards for secure key distribution or for image or configuration file updates.
The Cisco embedded ASR1000-RP1 deviates from the other ASR Series Route Processor 1 for the Cisco ASR 1006 router and the Cisco ASR 1004 Router in the following ways:
•Bulk file storage is on a large eUSB device (to 8GB (bytes) supported) with no SATA hard-drive supported.
•Redundant Cisco Router Processor 1 is not supported.
•Network clock changes. No second BITS clock input supported.
•A built-in 4xGE SPA is included. This shared port adapter provides 4 SFP-based GE connections.
Cisco Embedded ASR1000-SIP10 and SPAs for the Cisco ASR 1002 Router Description
The Cisco embedded ASR1000-SIP10 in the Cisco ASR 1002 Router is built into the Cisco ASR 1002 Router. The Cisco embedded ASR1000-SIP10 provides the physical and electrical termination for up to three half-height SPAs or one full-height and one half-height SPA. Double-wide SPAs are not supported. The fourth SPA slot is connected to the built-in 4xGE SPA that resides on the Cisco embedded ASR1000-RP1.
The Cisco embedded ASR1000-SIP10 interface, like the Cisco ASR 1006 Router and Cisco ASR 1004 Router, supports all Cisco embedded ASR1000-SIP10 functions and services. However, the Cisco embedded ASR1000-SIP10 differs in the following areas:
•Functions as the base board for Cisco embedded ASR1000-RP1
