ASR1009-X - Cisco ASR 1000 Series Aggregation Services Routers

Three interface-card positions for a larger ASR assembly

ASR1009-X is the Cisco ASR 1009-X chassis order. The manufacturer table supports three SIPs or Ethernet line cards, rather than the two listed for ASR1006-X. This difference matters when reserving interface-card capacity; it does not mean three populated cards are included in the sale.

Select carriers before counting usable adapter slots

With supported carrier arrangements, the ASR1009-X table lists twelve SPA slots or six EPA slots. The usable interface mix depends on the chosen carriers, adapters and software. Establish that bill of materials first, then count the required copper and optical links; do not equate a chassis slot allowance with a fixed port inventory.

Redundant slots still require a matched configuration

Two route-processor slots and two ESP slots are available in the modular architecture. Confirm processor compatibility, forwarding-card types, software support and the actual installed redundancy arrangement. Hardware slot availability alone is not evidence that a supplied unit has two processors or that a particular upgrade procedure is supported.

Allow for the enclosure and service clearances

Cisco lists a chassis height of 15.72 inches and 19-inch rack mounting. Its stated depth excludes protrusions such as module handles and cable-management brackets. Check the installation guide, rack clearance, power and cooling needs for the configured assembly. Verify service entitlement and licensing as separate procurement items.
