Rear Cards; Management I/O - Cisco ASR 5500 Installation Manual

ASR 5500 Hardware Platform Overview

Rear Cards

The ASR 5500 supports several types of rear-mounted cards:
•
•
•
The ARS 5500 supports ten rear cards. Each card is interconnected with the others via the switching fabric.

Management I/O

The ASR 5500 chassis supports two MIO /UMIO cards placed in the rear facing slots of the chassis. These
cards perform chassis management, as well as local context and non-local context external I/O operations.
Important
Each MIO/UMIO has:
• One CPU subsystem with 96 GB of RAM
• Four NPU subsystems
The two 10/100/1000Base-T (1GbE) ports on the front panel of MIO/UMIO cards can only be used for local
context (OAM). An MIO/UMIO includes support for:
• Midplane connections for chassis control operations
• SAS storage controller for FSC solid state drives (SSDs)
• RS-232 serial console (RJ45) for CLI management
• USB port for an external flash device
• 32 GB SDHC internal flash device
MIO/UMIO cards support two daughter card (DCs) for external I/O interfaces (100 Gbps aggregate per DC).
The optical ports on the daughter cards can only be used for non-local context. The currently available DC
supports ten 10 GbE interfaces. The interface ports accept SFP+ SR and LR transceivers.
For additional information see the MIO Cabling chapter.

UMIO cards, UDPCs and UDPC2s are direct replacements for MIO cards and DPC/DPC2s. However, a
special Universal PID license must be purchased and installed on the chassis for each installed UMIO and
UDPC/UDPC2. Contact your Cisco account representative for additional information.
The MIO/UMIO cards automatically implement 1:1 port redundancy (active/standby). Ports are 1:1
redundant across slots 5 and 6. For example, port 10 on the MIO in slot 5 is redundant with port 10 on the
MIO in slot 6.
