Caution: Archive Pre- G.07.2 x Configuration Files
A configuration file saved while using release G.07.2x (or greater) is not backward-compatible with earlier
releases. For this reason, HP recommends that you archive the most recent configuration on switches using
software releases earlier than G.07.2 x before you update any switches to software release G.07.2x or later.
Software Update Notice
Check the HP ProCurve web site frequently for free software updates for the various HP ProCurve switches
you may have in your network (see page 1).
Connectivity Note Regarding Gigabit-SX and -LX Port Settings for Links Between an HP
Series 4100GL Switch and Other Switch Models:
I
n the HP 1600M/2400M/2424M/4000M/8000M switches, and also in other vendors' switches, the default port
mode setting for the Gigabit-SX and Gigabit-LX ports is forced 1000FDx (Gigabit full-duplex). However, the
default port mode for the Gigabit-SX and -LX ports in the HP 4108GL is Auto. In earlier software releases, the
HP 4108GL tolerated this mismatch and allowed SX and LX links with these other switches to exist. The HP
4108GL (when running software release G.04.04 or greater) now complies with the Gigabit-SX and -LX standard
that disallows linkbeat to be enabled when there is a mismatch. (The HP 4104GL, introduced with software
release G.05.01, also complies with this requirement.) Thus, mismatched links between Gigabit-SX and -LX
ports on an HP Series 4100GL switch and the HP 1600M/2400M/2424M/4000M/8000M switches or other
switches that were formerly allowed will now fail. To avoid this problem either reconfigure the Gigabit-SX and
-LX ports to Auto on the HP 1600M/2400M/2424M/4000M/8000M switches or other switches, or reconfigure
the Gigabit-SX and -LX ports on the HP Series 4100GL switches to 1000FDx.
