Before you begin
CAUTION:
•Removing a blanking panel or module can significantly change
air flow within an operating enclosure. Each enclosure bay
must be populated for the enclosure to cool properly. Remove
a module or blanking panel from an enclosure bay only when
a new module is available to install in that bay.
•Parts can be damaged by electrostatic discharge. Use proper
antistatic 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.

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 strongly recommends using the HP Direct-Connect
External SAS Storage for HP BladeSystem Solutions Deployment Guide.
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.
IMPORTANT:
Cabling and zoning restrictions exist, based on the server type,
mezzanine slot, BladeSystem server device bay, BladeSystem
interconnect bay, and switch ports to which external SAS storage
enclosures are connected. For a quick reference of the
restrictions, see the printed 3Gb SAS BL Switch Zoning
Restrictions Important card that shipped with the switch. For
detailed planning information, see the HP Direct-Connect External
SAS Storage for HP BladeSystem Solutions Deployment Guide .
Selecting the interconnect bay
Each interconnect bay in the HP BladeSystem c-Class enclosure maps to
servers via the server mezzanine slot in which Smart Array Controllers
are installed. When selecting an interconnect bay for a SAS BL Switch,
make sure that the selected interconnect bay maps to the desired server
bays. For information about mappings, see the printed 3Gb SAS BL
Switch Zoning Restrictions Important card that shipped with the switch.
For information about supported SAS Controllers, see the HP 3Gb 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:
•The SAS BL Switch may be hot-installed in an operational en-
closure.
•Make sure that Smart Array SAS controllers are installed in
server mezzanine slots that map to the selected BladeSystem
c-Class enclosure interconnect bay.
•The 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. Alternatively, power can 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.
2. Prepare the switch.
3. Install the switch in the open interconnect bay.
4. Note the following during startup:
•When installed in an operational enclosure, the switch automat-
ically powers up and performs a series of Power On Self Tests.
•All eight switch Link LEDs will blink while the switch and the VSM
software are starting up.
•Startup time is approximately two minutes. If startup is longer
than two minutes, confirm that a supported version of Onboard
Administrator is installed on the system.
•After the switch and the VSM software have started up success-
fully, the switch Health LED will be solid green.
•If the Health LED is amber or off, remove the switch from the
BladeSystem enclosure Interconnect Bay and reinstall it, pressing
firmly on the switch and its locking latch handle to ensure it is
seated properly. If trouble persists, see the "Troubleshooting"
section of the HP BladeSystem enclosure setup and installation
guide.
For more information about switch LED patterns, see “Front panel
and LED definitions”on page 1.
NOTE:
Do not connect cables to the switch at this time. HP recommends
connecting cables only after confirming that the switch is
operational and has the desired, supported version of firmware
installed.
Accessing the switch
The switch is configured and managed through the HP Onboard
Administrator and HP Virtual SAS Manager (VSM) applications.
To access VSM:
1. Access Onboard Administrator (OA).
2. In the OA Systems and Devices navigation tree, expand the
Interconnect Bays, and select the HP SAS BL Switch.
3. After selecting the SAS switch to manage, click Management Console
and wait a few moments for the VSM application to open.
For more information about accessing and using the VSM, see the HP
3G Virtual SAS Manager User Guide.
