IMPORTANT: When the switch starts, it attempts to obtain an IP address from a DHCP
server. If the DHCP server is unreachable, the switch falls back to a static IP address, that is,
192.168.1.1. If a DHCP address is obtained then you must determine the IP address assigned
to the switch. To determine the IP address, access your DHCP server files or use LLDP (Link
Layer Discovery Protocol) commands on a connected device (such as another switch). For
more information on Initial Configuration, see Installation and Getting Started Guide available
at http://www.hpe.com/support/manuals.
5. Click Apply on the browser configuration screen to save your settings to retain them when the switch
is rebooted.
You are done with initial switch configuration. Disconnect the LAN cable from your PC and connect the
switch in to the network.
Be sure to return your PC to its original network settings before connecting to your network.
Mini-GBIS/SFP Installation Notes
NOTE: Use only genuine HPE Mini-GBIC/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 product. Use only an approved Laser
Class 1 SFP transceiver.
Use only genuine HPE Mini-GBIC/SFPs. Non-HPE Mini-GBIC/SFP transceivers are not supported. Use
of genuine Hewlett Packard Enterprise products ensures that your network maintains optimal performance
and reliability. Should you require additional transceivers, please contact a Hewlett Packard Enterprise
sales representative or an authorized reseller.
Hot Swapping Mini-GBIC/SFP transceivers. Supported mini-GBIC/SFP transceivers that you can install
in your Hewlett Packard Enterprise switch can be “hot swapped”– removed and installed while the switch
is receiving power. You should disconnect the network cables from the mini-GBIC/SFP transceivers before
hot-swapping them, though.
When you replace a mini-GBIC/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.
Mini-GBIC/SFP Connections to Devices with Fixed Speed/Duplex Configurations. When connecting
a device to your switch port that contains a mini-GBIC/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 Hewlett Packard Enterprise
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 mini-GBIC/SFP ports
are properly configured. At a minimum, make sure the configurations match.
