Introduction
The Cisco MDS 9250i Multiservice Fabric Switch (DS-C9250I-K9) is an optimized platform for
deploying high-performance SAN extension solutions, distributed intelligent fabric services, and
cost-effective multiprotocol connectivity for both open systems and mainframe environments.
The Cisco MDS 9250i switch is an ideal solution for local office and remote branch-office SANs and
also in large-scale SANs operating the Cisco MDS 9700 and 9500 Series Multilayer director platforms.
The Cisco MDS 9250i switch offers 40 autosensing 2-, 4-, 8-, and 16-Gbps line-rate Fibre Channel ports,
eight 10-Gigabit Ethernet Fibre Channel over Ethernet (FCoE) ports, and two 10-Gigabit Ethernet IP
storage services ports in a fixed two-rack-unit (2RU) form factor.
The Cisco MDS 9250i switch can be deployed in the existing native Fibre Channel networks, which
ensures protection of your investments in storage networks. Two 1- and 10-gigabit ports support Small
Computer System Interface over IP (iSCSI) storage services. By using the eight 10 Gigabit Ethernet
FCoE ports, the Cisco MDS 9250i switch can be attached to the directly connected FCoE and Fibre
Channel storage devices. The Cisco MDS 9250i switch supports multi-tiered unified network fabric
connectivity directly over FCoE. The Cisco MDS 9250i switch has front-to-back airflow and comes with
a set of storage services for Fibre Channel and FCoE SANs with FCIP, IO accelerator (IOA), and data
mobility migration (DMM).
The Cisco SAN Extension over IP application package license is enabled as standard on the two fixed
1/10 Gigabit Ethernet IP storage services ports, enabling features such as Fibre Channel over IP (FCIP)
and compression on the switch without additional licenses.
The Cisco MDS 9250i switch is shipped with the following:

which provides one RS-232 console port and one MGMT 10/100 Ethernet port for the integrated
supervisor module
•
Three power supplies that are redundant by default
•
Two hot-swappable fans that are redundant by default
Cisco MDS 9250i Integrated Supervisor Module
The nonremovable Cisco MDS 9250i integrated supervisor module provides the control and
management functions of the Cisco MDS 9250i Multiservice Fabric switch, and it includes 40 integrated
16-Gbps Fibre Channel switching ports and eight 10-Gigabit Ethernet Fibre Channel over Ethernet
(FCoE) port modules.
The Cisco MDS 9250i integrated supervisor module has a PowerPC 8572E processor. It also has an
internal CompactFlash card that provides 4 GB of storage for software images. The NVRAM consists of
a battery, a battery controller and 512 Kx16 SRAM. SRAM used to store event logs, core dumps that are
required to be stored after a power cycles.

Fan Modules
Fan Modules
The Cisco MDS 9250i switch has two fan trays that are installed vertically at the back of the chassis.
Each fan module can be removed while the other fan module continues to move air through the chassis.

Figure 1-4
One fan can fail without affecting the thermal performance of the system. Redundant fan controllers and
other internal mechanisms are in place to ensure that any single fan tray does not go down.
If any single fan fails, the system continues to operate under all conditions. Two fan failures might cause
alarms from ASIC when the temperature exceeds the threshold. At 104°F (40°C) or less, a single fan tray
can be removed and the system can continue to operate long enough to allow for replacement of a failed
fabric module or fan tray.

Power Supplies
Power Supplies
The Cisco MDS 9250i Multiservice Fabric switch supports the following types of power supplies:
•
300-W AC power supply (AC input and DC output)
•
300-W DC power supply (DC input and DC output)
The Cisco MDS 9250i Multiservice Fabric switch supports up to three hot-swappable 300-W AC power
supplies (AC input) (DS-C50I-300AC).
When connected to 220 VAC, the 300-W AC power supplies (DS-C50I-300AC) for the Cisco MDS 9250i
switch provide an output power of 300 W to power the modules and fans. When connected to a 110 VAC
power system, the power supply provides approximately 300 W. In this case, and if the power supplies
are used in redundant rather than combined mode, they might not provide adequate power, depending on
the number of modules loaded in the chassis.

Figure 1-5
Each power supply module monitors its output voltage and provides the status to the supervisor. The
power supply modules also provide information about local fans, power, shutdown control, and
E2PROM to the supervisor.

Supported Transceivers
Supported Transceivers
The Cisco MDS 9250i switch supports these transceivers: 1000BASE-T, RJ-45, 8-Gbps SW/LW, LC
Enhanced Small Form-Factor Pluggable (SFP+), 10-Gbps SW/LW, LC SFP+, 10-GbE SR/LR/ER, LC,
SFP+, and 16-Gbps SW/LW LC SFP+.
Fibre Channel SFP+ Transceivers
The Fibre Channel SFP+ transceivers are field-replaceable and hot-swappable. You can use any
combination of SFP+ transceivers that are supported by the switch. The only restrictions are that SWL
transceivers must be paired with SWL transceivers, and LWL transceivers must be paired with LWL
transceivers, and the cable must not exceed the stipulated cable length for reliable communications.
For more information about a specific Cisco SFP+ transceiver, see the “SFP+ Transceiver
Specifications” section on page B-3. SFP+ transceivers can be ordered separately or with the Cisco MDS
9250i switch.
Note
Use only Cisco transceivers in the Cisco MDS 9250i switch. Each Cisco transceiver is encoded with
model information that enables the switch to verify that the transceiver meets the requirements for the
switch.
