Enabling communication between system management adapters
The two types of system management adapters are
2
:
v The Integrated System Management Processor (ISMP) integrated on the planar
board of each engine of the NAS Gateway 300
Provides basic operational status about key engine components, such as its
processors, power supplies, fans, and so on.
v An optional Remote Supervisor Adapter (RSA) that can connect to up to twelve
of the ISMPs
The RSA allows you to connect through a LAN or modem from virtually anywhere
for extensive remote management. The RSA works in conjunction with the ISMP
of the NAS Gateway 300 and an interconnect cable that connects multiple
engines to the ISMP. Remote connectivity and flexibility with LAN capability is
provided by Ethernet connection. Along with ANSI terminal, Telnet, and IBM
Director, the RSA enables more flexible management through a Web browser
interface.
For more information, see “Using the RSA” on page 80.
Table 6 provides a summary of the features of the ISMP and the RSA.
The light-path diagnostics LED status that is available through the ISMP includes:
v Power-supply failure
v Insufficient power for power-supply redundancy
v Exceeded power-supply capabilities
v Non-maskable interrupt occurred
v Over heating
v Fan failure
v
Memory error
v
Microprocessor failure
v
PCI-bus error
v
VRM failure
v
Planar SCSI failure for system disk or internal tape drive (if any)
Remote status includes information on power supply voltages, voltage-regulator
module (VRM) readings, temperatures of system components, system power status,
power-on hours, fan status, and system state.

2. A third might be referred to in some of the documentation that came with your system, but that adapter is not used in the NAS
Gateway 300.
