◦Brocade 16Gb/28-ports enabled SAN Switch Pwr Pk+ HP BladeSystem c-Class
•HP Read Me First document
•HP End User License Agreement letter
Installation and safety considerations
The 16Gb SAN Switch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure.
See the appropriate BladeSystem Enclosure Setup and Installation Guide for specific enclosure
requirements.
Installing multiple switches
If you do not have a DHCP server connected to the OA, install and configure one 16Gb SAN
Switch at a time. This is required so that Ethernet IP address conflicts do not occur with duplicate
default Ethernet IP addresses.
IMPORTANT: DHCP is enabled by default on this switch. In cases where DHCP is available, IP
address conflicts do not occur, simplifying multiple switch installations. See “Using external DHCP
” (page 14). See also the most current documentation for interconnects and other HP BladeSystem
c-Class components at the HP website: http://www.hp.com/go/bladesystem/interconnects.
Each switch must be assigned a unique Ethernet IP address during configuration. Once the default
Ethernet IP address on the 16Gb SAN Switch has been changed, you may install additional 16Gb
SAN Switches in the enclosure.
See the appropriate HP BladeSystem Enclosure Setup and Installation Guide for help identifying
your specific enclosure setup, available connections, and power requirements.
Electrical considerations
The 16Gb SAN Switch requires 35 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 16Gb SAN Switch must be inserted into any
ports where SFPs are not installed, to help contain air flow in the BladeSystem chassis.
Kit contents 11

Installing the 16Gb SAN Switch
For help identifying your specific enclosure setup and available connections, see the HP BladeSystem
c-Class Enclosure Setup and Installation Guide, provided with your enclosure, or the HP website
http://www.hp.com/go/bladesystem/documentation.

NOTE: The HP BladeSystem c7000 Platinum Enclosure is required to permit 16 Gbps speed.
Other HP BladeSystem c7000 Enclosures have a maximum speed of 8 Gbps.
OA power verification
The OA is the enclosure management processor that manages the devices contained within the
enclosure. The OA provides a single point from which to perform basic management tasks on
switches or server blades installed in the enclosure.
IMPORTANT: HP recommends reading the appropriate HP BladeSystem Enclosure User Guide
and the HP BladeSystem Onboard Administrator User Guide. Reading these guides in sequence
will promote an overall understanding of your specific enclosure model.
Once the switch is installed in the interconnect bay, the OA verifies that the switch type matches
the mezzanine cards present on the servers. If there is no mismatch, the OA powers up the switch.
If the switch does not power up, check the enclosure and switch status with the OA web interface.
See the HP BladeSystem Onboard Administrator User Guide for more information.
Verifying the configuration
The OA is the enclosure management module that supports and manages the HP BladeSystem
c-Class enclosure and all the devices used in the enclosure.
Once the switch is installed in the interconnect bay, the OA verifies that the switch type matches
the mezzanine cards present on the server blades. If there is no mismatch, the OA powers up the
switch.
If the switch does not power up, check the enclosure and switch status using the OA web interface.
See the HP BladeSystem Onboard Administrator User Guide for more information and
troubleshooting tips.

2. Issue portdisable portnumber command, where portnumber is the number of the port
you want to disable.
Using DPOD
DPOD functionality does not require a predefined assignment of ports. Port assignment is determined
by the total number of ports in use as well as the number of purchased ports.
The DPOD feature simplifies port management by:
•Automatically detecting HBA connected server ports or cabled ports
•Automatically enabling ports
•Automatically assigning port licenses
To initiate DPOD, use the licensePort command, as described in Page 18.
IMPORTANT: For the Brocade 16Gb SAN Switch, DPOD works only if the server blade is installed
with an HBA present. A server blade that does not have a functioning HBA is not treated as an
active link for the purpose of initial POD port assignment.
DPOD commands
Use the licensePort command to manage dynamic POD assignments with the following options:
•licensePort –reserve portnum reserves a future license assignment for a specific port,
even if the port is currently offline.
•licensePort –release portnum removes a license from a port.
•portCfgPersistentDisable blocks a specific port from future assignments.
•licensePort -show displays an overview of the POD license status and port assignments.

NOTE: The DPOD feature does not consider disabled ports as candidates for license assignments.
You can persistently disable an otherwise enabled port to cause it not to come online and preserve
a license assignment for future use.
Backing up the configuration
To back up the switch configuration to an FTP server, enter configupload and follow the prompts.
The configupload command copies the switch configuration to the server, making it available
for downloading to a replacement switch, if necessary.

3 Managing the 16Gb SAN Switch
Management features
The management tools built into the 16Gb SAN Switch (listed in Table 6 (page 20)) can be used
to monitor fabric topology, port status, physical status, and other information used for performance
analysis and system debugging.
When running IP over FC, these management tools must be run on both the Fibre Channel host
and the switch, and must be supported by the FC host driver. For a list of FC hosts supported by
the 16Gb SAN Switch, contact your HP representative.

You can connect a management station to one switch with Ethernet while managing other switches
connected to the first switch with FC. To do so, set the FC gateway address of each of the other
switches to be managed to the FC IP address of the first switch.
The gateway address of the first switch should be set to whatever the gateway address is for the
subnet on which the first switch resides. See Table 7 (page 20).

Maintaining the 16Gb SAN Switch
The 16Gb SAN Switch does not require any regular physical maintenance.
It is critical, however, that environmental conditions, described in Environmental
requirements (page 33), are met to help prevent switch failure due to heat stress or improper air
flow.
