ALOM System Controller Card
Caution –
Although access to the Advanced Lights Out Manager (ALOM) system
controller through the network management port is secure, access through the serial
management port is not secure. Therefore, avoid connecting a serial modem to the
serial management port.
The ALOM serial management port (labeled SERIAL MGT) and network
management port (labeled NET MGT) are present in the Solaris OS device tree as
/dev/ttya
, and in the OpenBoot configuration variables as
ttya
. However, the
serial management port does not function as a standard serial connection. If you
want to attach a standard serial device to the system (such as a printer), you need to
use the DB-9 connector on the system back panel, which corresponds to
/dev/ttyb
in the Solaris OS device tree, and as
ttyb
in the OpenBoot configuration variables.
See the Netra 440 Server Product Overview (817-3881-xx) for more information.
■
The ALOM system controller card is installed in a dedicated slot on the system
motherboard. Never move the ALOM system controller card to another system
slot, as it is
not a PCI-compatible card.
■
The ALOM system controller card is not a hot-swappable component. Before
installing or removing the ALOM system controller card, you must power off the
system and disconnect all system power cords.
■
The serial management port on the ALOM system controller card cannot be used
as a conventional serial port. If your configuration requires a standard serial
connection, use the DB-9 port labeled “TTYB” instead.
■
The 10BASE-T network management port on the ALOM system controller card is
reserved for use with the ALOM software and the system console. The network
management port does not support connections to 100 Mbps or Gigabit networks.
If your configuration requires a high-speed Ethernet port, use one of the Gigabit
Ethernet ports instead. For information on configuring the Gigabit Ethernet ports,
refer to the
Netra 440 Server Installation Guide (817-3882-xx).
■
The ALOM system controller card must be installed in the system for the system
to function properly.
■
The ALOM system controller card is not a conventional PCI card. Do not attempt
to install the ALOM system controller card into a PCI slot. In addition, do not
attempt to install a PCI card into the ALOM system controller slot.
Note –
All internal devices, except hard drives, must be installed only by qualified
service personnel.
