Technical data

such as priming a processor for reload, also require you to use the Low-Level Link. The OSM installer
(on the NonStop System Console Installer DVD) installs the LLL only if you select the dedicated
service LAN option during installation.
NOTE: The features described in this section will vary by Low-Level Link version, as noted.
Figure 16 OSM Low-Level Link Main Window
The OSM Low-Level Link looks and functions like the TSM Low-Level Link Application, with the
following exceptions:
• Only the OSM Low-Level Link supports NonStop BladeSystems, NS-series servers and S-series
modular I/O. Rather than through service processors, the OSM LLL communicates with NonStop
systems through the maintenance entities (MEs). For NS-series, they are located in the ServerNet
switch boards in p-switch modules; for NonStop BladeSystems, they are located in the ServerNet
switches in the blade enclosure.
• The OSM Low-Level Link allows you to copy and update HSS firmware file required for all
NonStop systems running J-series software except for NS2000 series systems.
NOTE: For a user (other than the default users preconfigured on NonStop system consoles)
to perform the "Update HSS" or "Copy HSS Files" action, you must give that user the necessary
OpenSSH permissions on the NSC, as described in “Configuring Non-Default Users”.
