Running Connectivity Tests
Both the hub and cabling can be tested by running an end-to-end communica-
tions test -- a test that sends known data from one network device to another
through the hub -- such that you can verify that the data was correctly
transmitted between the devices.
See your LAN adapter’s manual for information on running an end-to-end
communication test.
Obtaining Firmware Enhancements
In the future, Hewlett-Packard may provide improvements to this product
through firmware upgrades. The upgrade code can be downloaded from a PC
attached to the hub’s RS-232 port or over the network. The update procedures
are described in documents that come with the firmware enhancements.
You can determine the current firmware version on the hub from the ASCII
console. Look for the SNMP Agent EEPROM version number to determine the
revision. When you access the console, the version number appears.
