6 Maintenance and Support Connectivity
Local monitoring and maintenance of the NonStop BladeSystem occurs over the dedicated service
LAN. The dedicated service LAN provides connectivity between the system console and the
maintenance infrastructure in the system hardware. Remote support is provided by OSM, which
runs on the system console and communicates over the HP Instant Support Enterprise Edition
infrastructure or an alternative remote access solution.
Only components specified by HP can be connected to the dedicated LAN. No other access to
the LAN is permitted.
The dedicated service LAN uses a ProCurve 2524 Ethernet switch for connectivity between the
c7000 enclosure, CLIMs, IOAM enclosures, and the system console.
The HP ISEE call-out and call-in access is provided by the hpVPN Cisco 831 router, which connects
to the customer internet access. Alternatively, call-out and call-in access is provided by a modem.
NOTE: Your account representative must place a separate order of the ISEE VPN router with
the assistance of the ISEE team.
An important part of the system maintenance architecture, the system console is a personal
computer (PC) purchased from HP to run maintenance and diagnostic software for NonStop
BladeSystems. Through the system console, you can:
• Monitor system health and perform maintenance operations using the HP NonStop Open
System Management (OSM) interface
• View manuals and service procedures
• Run HP Tandem Advanced Command Language (TACL) sessions using terminal-emulation
software
• Install and manage system software using the Distributed Systems Management/Software
Configuration Manager (DSM/SCM)
• Make remote requests to and receive responses from a system using remote operation
software
Dedicated Service LAN
A NonStop BladeSystem requires a dedicated LAN for system maintenance through OSM. Only
components specified by HP can be connected to a dedicated LAN. No other access to the LAN
is permitted.

Basic LAN Configuration
A basic dedicated service LAN that does not provide a fault-tolerant configuration requires
connection of these components to the ProCurve 2524 maintenance switch installed in the modular
cabinet as shown in example :
