Installation and safety considerations
The Cisco MDS 9124e Fabric Switch installs in the I/O bays in the rear of the HP c-Class
BladeSystem enclosure. Refer to the HP BladeSystem c7000 Enclosure setup and installation guide
for specific enclosure requirements.

Installing multiple switches

Install and configure one Cisco MDS 9124e Fabric Switch at a time. Each switch must be assigned a
unique Ethernet IP address during configuration. Once the IP address on the Cisco MDS 9124e
Fabric Switch has been set, you may install additional switches in the enclosure. See the HP
BladeSystem c7000 Enclosure setup and installation guide for help identifying your specific
enclosure setup, available connections and power requirements.

Electrical considerations

The Cisco MDS 9124e Fabric Switch requires 55 watts, provided by the enclosure. No other power
requirement or provision exists.

Environmental considerations

Ensure proper cooling and ventilation by verifying the following:
•The air vents on the enclosure are not blocked or restricted.
•The ambient air temperature at the front of the enclosure does not exceed 35°C (95°F) while the
switch is operating.
IMPORTANT:
The dust covers that ship with your Cisco MDS 9124 e Fabric Switch must be inserted into any ports
where SFPs are not installed, to help contain air flow in the BladeSystem chassis.
Installing the Switch
CAUTION:
Do not install multiple switches at the same time with default addresses or an address conflict will
occur. See ”Setting the IP address” for more information.
The Cisco MDS 9124e Fabric Switch is a hot-pluggable device. The enclosure power may be on or
off when inserting the switch. Follow these steps to install the switch:
