Chapter 12 Cisco ASR 1001 Router Overview and Installation
Seven 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. Each individual fan also has a fan fail status signal. The fan fail
signal is asserted if the fan speed falls below 50% of the rated speed. The fans are numbered from zero
(0) to 6, left to right.
Two power supplies, either two AC power supplies or two DC power supplies are accessed from the rear
of the router.
Cisco ASR 1001 Router Slot Numbering
The SPA bay numbering scheme for Cisco ASR 1001 Router is different from the Cisco ASR 1000 SIP
card. The SPA ordering is: Built-in GE ports (SPA 0), SPA Bay 1 (SPA 1), and I/O Board (SPA 2).
The integrated daughter card is not necessarily a SPA; it could be any I/O, such as a harddrive or USB.
When the daughter card is not a SPA, then SPA Bay 2 will be left blank and not present in the system.
The built-in GE ports are logically SPA bay 0 and will be addressed as GE 0/0/x. The half-height SPA
slot is logically SPA bay 1 and ports will be addressed as 0/1/x. Ports on the integrated daughter card are
logically in SPA bay 2 and will be addressed as 0/2/x.

Cisco ASR 1001 Router Components
The Cisco ASR 1001 Router system is derived from the architecture of the other Cisco ASR 1000 Series
routers. The Cisco ASR 1001 Router contains a single mainboard that provides all the functions of a
Cisco ASR1000-RP (route proce4ssor), a Cisco ASR1000-SIP (carrier card), and a Cisco ASR1000-ESP
(forwarding processor). This mainboard assembly also contains a built-in 4x1 GE SPA providing four
SFP ports. The Cisco ASR1000-RP section of the mainboard provides all the traditional management
interfaces (Ethernet, Console, Aux) and a storage interface (USB only). The Cisco ASR1000-SIP section
provides one half-height SPA bay and a supports a flexible integrated daughter card. The Cisco
ASR1000-ESP section provides a CPP based forwarding engine including a security coprocessor.
