Chassis Slot and Logical Interface Numbering
The Cisco ASR 1000 Series Routers have a slot numbering system located on both sides of the card
module location. The chassis slots are physically numbered from zero starting at the bottom of t he
chassis. This section describes the slot numbering for the Cisco A SR 1000 Series Routers:
• Cisco ASR 1006 Router Slot Numbering, page 1-5
• Cisco ASR 1004 Router Slot Numbering, page 1-7
• Cisco ASR 1002 Router Slot Numbering, page 1-7
Cisco ASR 1000 Series SPA Interface Processor (SIP) subslots begin their numbering with “0” and have
a horizontal orientation. The SIP subslot numbering is indicated by a small numeric label beside the
subslot on the faceplate. Some commands allow you to display information about the SPA itself, such as
show idprom module and show hw-module subslot. These commands require you to specify both the
physical location of the SIP and SPA in the format, Slot/Subslot, where:
• Slot—Specifies the chassis slot number in the Cisco ASR 1000 Series Routers wh ere the SIP is
installed.
• Subslot—Specifies a subslot of the SIP where the SPA is installed.
