Cisco ASR 1001 Chassis Rear View
The following ima shows the rear of the Cisco ASR 1001 Router with seven fans and two AC or DC power
supplies.
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.
