MPS-14/2 Module Upgrade
Caution
A software upgrade is only partially disruptive for the MPS-14/2 module. The SAN-OS software
continues to support nondisruptive software upgrades for Fibre Channel modules in the switch and for
the switch itself.
The MPS-14/2 modules have 14 Fibre Channel ports (nondisruptive upgrade) and 2 Gigabit Ethernet
ports (disruptive upgrade). MPS-14/2 modules use a rolling upgrade install mechanism for the two
Gigabit Ethernet ports where each module in a given switch can only be upgraded in sequence. To
guarantee a stable state, each MPS-14/2 module in a switch requires a 5-minute delay before the next
module is upgraded.
Supported Hardware
You can configure the FCIP and iSCSI features using one of more of the following hardware:

Configuring Gigabit Ethernet Interfaces
Both FCIP and iSCSI rely on TCP/IP for network connectivity. On each IPS module or MPS-14/2
module, connectivity is provided in the form of Gigabit Ethernet interfaces that are appropriately
configured. This section covers the steps required to configure IP for subsequent use by FCIP and iSCSI.
Note
For information about configuring FCIP, see
configuring iSCSI, see
A new port mode, called IPS, is defined for Gigabit Ethernet ports on each IPS module or MPS-14/2
module. IP storage ports are implicitly set to IPS mode, so it can only be used to perform iSCSI and FCIP
storage functions. IP storage ports do not bridge Ethernet frames or route other IP packets.
Each IPS port represents a single virtual Fibre Channel host in the Fibre Channel SAN. All the iSCSI
hosts connected to this IPS port are merged and multiplexed via the single Fibre Channel host.
In large scale iSCSI deployments where the Fibre Channel storage subsystems require explicit LUN
access control for every host device, use of proxy-initiator mode simplifies the configuration.

In both the MPS-14/2 module and the Cisco MDS 9216i integrated supervisor module, the port
numbering differs for the Fibre Channel and the Gigabit Ethernet ports. The Fibre Channel ports
are numbered from 1 through 14 and the Gigabit Ethernet ports are numbered as 1 and 2.
