(Optional) Configure the Switch for Management.
By factory default, the switch will automatically obtain its IP
network configuration from a DHCP or BootP server. Subsequently,
you can determine the IP address assigned to the switch by
inspecting your DHCP/BootP server, or by using LLDP from a
connected device.
You can also manage and configure the switch through a console
port connection. Connect a VT-100 terminal or PC (with suitable
terminal emulation software) to the switch using the serial cable
(DB-9 and RJ-45 connectors) supplied with the switch.
* Note: You can also connect a console to the switch via the USB
console port (cable not provided). For more information on using
the USB console port, see the switch Installation and Getting
Started Guide for your switch.
For information on configuration and remote management, see the
Management and Configuration Guide for your switch. The
manuals are available at www.hp.com/networking/support.
SFP Installation Notes
Note
Use only genuine HP SFP transceivers supported by your switch.
When selecting a fiber SFP device, make sure it can function at a temperature that is not less than the recommended
maximum operational temperature of the switch. Use only an approved Laser Class 1 SFP transceivers.
Use only genuine HP SFPs. Non-HP SFP transceivers are not supported. Use of genuine HP products ensures that your network
maintains optimal performance and reliability. Should you require additional transceivers, please contact an HP sales representative or an
authorized reseller.
Hot Swapping SFP transceivers. Supported SFP transceivers that you can install in your HP switch can be "hot swapped" – removed
and installed while the switch is receiving power. You should disconnect the network cables from the SFP transceivers before hot-swapping
them, though.
When you replace an SFP transceiver with another of a different type, the switch may retain selected port-specific configuration settings
that were configured for the replaced unit. Be sure to validate or reconfigure port settings as required.
SFP Connections to Devices with Fixed Speed/Duplex Configurations. When connecting a device to your switch port that contains
an SFP transceiver, the speed and duplex settings of the switch port and the connected device must match. Otherwise, the device may not
link properly — you may not get a link. For some older network devices, including some older HP devices, the default speed/duplex settings
may be predefined (for example, to 1000 Mbps/Full Duplex), or otherwise set differently from the default configuration of your switch port.
Because of these default speed/duplex considerations, you should make sure that devices connected to your SFP ports are properly
configured. At a minimum, make sure the configurations match.
