Before you begin
CAUTION:
• Removing a module can significantly change air flow within
an operating enclosure. Each enclosure bay must be populated
with a module or blanking panel for the enclosure to cool
properly. Remove a module or blanking panel from an enclos-
ure bay only when a new module is available to install in that
bay.
• Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. For more information, see HP c-Class
BladeSystem or SAS BL Switch user guides.
• For safety information and regulatory notices, see the SAS BL
Switch user guides.
Getting started
• Familiarize yourself with information available on the HP BladeSystem
website: http://ww w.hp.com/go/bladesystem.
• Navigate thro ugh the HP BladeSystem website to learn more about
BladeSystem c-Class enclosures, this SAS BL Switch, mezzanine
cards, servers, and other BladeSystem compone n ts. Pr odu ct pages,
overviews, QuickSpecs, and user documents for all BladeSystem
products are accessible from this website.
• Scroll down the left pane of the HP BladeSystem website and click
Technical Resources to access to the HP BladeSystem Technical
Resources page. Tabs across the top of this page provide access
points to planning, installation, maintenance, and troubleshooting
information. User documents for all BladeSystem components are
located on the Installing tab.
• Obtain the following documents; they are needed when planning,
installing, and configuring the switch:
• HP BladeSystem Deployment Guide for Solutions with 6Gb SAS
BL Switches and External SAS Storage Enclosures
• HP 6G Virtual SAS Manager User Guide
• HP StorageWorks 6Gb SAS BL Switch User Guide
• HP BladeSystem 6Gb SAS BL Switch QuickSpecs
These documents are available on the BladeSystem Technical Re-
sources page (described above) and on the HP Manuals page at
nl
http://www.hp.com/support/manuals.
Planning the configuration
For both single- and dual-domain deployments, a variety of cabling and
configuration strategies are available. Consider the server blades,
switches, external storage enclosures, and external backup devices in
your deployment and develop plans for cabling the external devices and
for zoning the switch to control access to the storage.
For assistance, HP recommends using the HP BladeSystem Deployment
Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage
Enclosures. The deployment guide provides guidelines, instructions, and
configuration examples for solutions centered around an HP BladeSystem
c-Class enclosure with server blades, SAS BL switches, SAS mezzanine
cards, and external SAS storage enclosures.
Selecting the interconnect bay
HP BladeSystem c-Class enclosure interconnect bays map to servers via
the slots in which the mezzanine cards are installed in the server blades.
When selecting an interconnect bay for a switch, make sure that the
selected bay maps to the desired server blades. For information about
mappings, see the user documents for your BladeSystem c-Class enclosur e
model. For information about supported mezzanine cards, see the HP
6Gb SAS BL Switch QuickSpecs.
IMPORTANT:
This switch can be deployed 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
BladeSystem c-Class enclosure.
Installing the switch
NOTE:
• Make sure that mezzanine cards are installed in server
mezzanine slots that map to the selected BladeSystem c-Class
enclosure interconnect bay.
• The 6Gb SAS BL Switch may be hot-installed in an operational
enclosure.
• The 6Gb SAS BL 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. Power can also be
applied or removed through the Onboard Administrator applic-
ation.
• Connect SAS cables to external storage enclosures only after
confirming that the desired firmware version is installed on the
switch.
1. Remove the air baffle from the selected interconnect bay.
