Planning the configuration

Before installing the switch, analyze the servers and storage and develop a plan for controlling access to the storage. After installing the switch, configure the switch and the storage per the plan (“Configuring the

switch ” on page 3).

Selecting the interconnect bay

Each c3000 and c7000 interconnect bay maps to servers via the slot in which the mezzanine cards are installed in the server blades. When selecting interconnect bays for switches, make sure that the selected bays map to the desired server blades. For information about mappings, see the user documents for your c-Class enclosure model. For information about supported mezzanines, see the 3Gb SAS Switch QuickSpecs.

IMPORTANT:

This switch is supported for use in both single- and dual-domain environments. When used in dual-domain configurations, the two switches must be installed in the same row of the c-Class enclosure.

1. Remove the air baffle from the selected interconnect bay.

2. Prepare the switch.

Installing the switch

NOTE:

• The 3Gb SAS Switch may be hot-installed in an operational

enclosure.

• Make sure that the mezzanine cards are installed in server

mezzanine slots that map to the selected c-Class enclosure interconnect bay.

• The 3Gb SAS Switch does not have a power on/off button.

Power is automatically applied or removed when the switch is installed or removed from the enclosure. Alternatively, power can be applied or removed through the Onboard Administrator application.

• Connect SAS cables to external storage enclosures only after

confirming that the desired firmware version is installed on the switch.

For illustration purposes, the following images demonstrate installing a 3Gb SAS Switch in interconnect bay 5 of a BladeSystem c7000 enclosure.

3. Install the switch in the open interconnect bay.

When installed in an operational enclosure, the switch automatically powers up and performs a series of Power On Self Tests.

A successful installation is indicated by a green Health LED (“Front

panel and LED definitions” on page 1). If the Health LED is amber

or there is no power to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and installation guide.
