Cisco UCS S3260 Storage Server Chassis Installation and Service Guide
Chapter 3 Maintaining the System
Installing or Replacing System Components
Replacing a System I/O Controller (SIOC)
The system can support up to two system I/O controllers (SIOCs).
For information about the management architecture and the chassis management controller (CMC) that
is in each SIOC, see
Management Architecture, page 1-8
This section contains the following topics:
•
Replacing a SIOC in a Single-SIOC System, page 3-29
•
Replacing a SIOC in a Dual-SIOC System, page 3-30
•
Setting SIOC QSFP Port Speed, page 3-31
•
Updating SIOC Adapter Firmware in a System With Dual SIOCs But Only One Server Node,
page 3-31
•
Migrating From Version 02 SIOC to Version 03 SIOC, page E-14
Note
If you are replacing a Version 02 SIOC (UCSC-S3260-SIOC) with a Version 03 SIOC
(UCS-S3260-PCISIOC), use the procedure in
Migrating From Version 02 SIOC to Version 03 SIOC,
. Version 03 SIOCs require Cisco IMC 4.0(1
n
) or later and for UCS Manager-controlled
systems, Cisco UCS Manager 4.0(1
n
) or later.
Note
The Version 03 SIOC is supported only with S3260 M5 or later server nodes.
Note
Do not mix different versions of SIOCs in the same system.
Note
If your system has two Version 03 SIOCs, they must have identical adapter cards. Do not mix adapter
cards between Version 03 SIOCs in a system.
Note
A Version 01 SIOC from a Cisco C3160 system cannot be installed in a Cisco S3260 system.
Note
If you move a SIOC from one chassis to another, the SIOC’s CMC configuration is treated as
incompatible and is automatically deleted. The CMC will sync with the active CMC configuration.
