Switch User Manual

Consider these prerequisites before installing your switch module:
• Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade server
with blanks.
• Identify the bays inwhichyouwill insert the switchmodules.Plan to install thefirst switchmodule
in bay 1, the second in bay 2, and so on up to bay 8, if possible. The bay in which you choose to
install each switch module depends on whether mezzanine or Ethernet cards are installed in the
blade server and how they are configured. See the blade server documentation for more
information about installing and configuring the mezzanine or Ethernet cards.
The interconnect module bays are physically interconnected in pairs through the blade server
backplane. That is, each of these pairs—bays 1 and 2, bays 3 and 4, bays 5 and 6, and bays 7 and
8—are interconnected. If you install two switch modules in one of the paired bays, they are
internally interconnected. You must configure the switch modules to logically enable the
interconnect ports, Gigabit Ethernet ports 23 and 24. See the switch module software
configuration guide for information on configuring these ports.
• See the HP c-Class documentationfor informationon the port mapping betweenblade serversand
the switch modules.
4 Installing the Switch Module in the Blade Server
Before you install the switch module in the blade server, consider these points:
• Review and become familiar with the safety guidelines in the Regulatory Compliance and Safety
Information for the Cisco Catalyst Blade Switch 3020 for HP that accompanies this guide.
• Review and become familiar with the safety guidelines in the HP BladeSystem enclosure setup and
installation guide.
• Review and become familiar with the temperature, power, and grounding requirements specified
in the HP BladeSystem enclosure setup and installation guide.
Warning Only trained and qualified personnel should be allowed to install, replace, or service
this equipment. Statement 1030
Caution To prevent electrostatic-discharge (ESD) damage when installing switch modules, follow
your normal board and component handling procedures.
Note When you install a switch module, you do not need to power down the blade server.
