Choosing Between a Rack and a Cabinet
Netra t1 servers can be installed in either racks or cabinets. Factors that may
influence your decision include:
■ Security
If other people have access to the room in which your Netra systems are located,
you can increase security by locking the systems in a cabinet.
■ Thermal issues
Cabinets often require additional fans, because the systems you install in them are
generating heat in an enclosed space. Two-post racks, however, may require no
special cooling systems.
■ Flooring
Two-post telco relay racks are designed so that cables can be run overhead.
Cabinets often require cables to be run under the floor.

Calculating the Power Requirements for your Netra t1
A Netra t1 system containing two disk drives has an estimated power requirement
of approximately 1amp.
TABLE 2-2 shows the estimated power consumed by the individual components in a
fully powered system (that is, in a system with a Power Supply Unit (PSU) operating
at 100% efficiency). However, when you are calculating the power requirements for
your system, you must allow for 65% PSU efficiency. To perform this calculation,
add the figures (from the third column of
the system. Then divide the result by 0.65. Below are two examples.
TABLE2-2 Estimated Power Consumption of the Components of the Netra t1

Example A
The power requirement for a Netra t1 system operating at 65% PSU efficiency and

Chapter 2 Operating Power and Cooling 9
Example B
The power requirement for a Netra t1 system operating at 65% PSU efficiency and
containing:
■ 440 MHz CPU
■ 1Gbyte RAM
■ Two 18 Gbyte disk drives

108.4W=
Note – To calculate the total power requirement for several Netra t1 systems
installed in a single rack or cabinet, add together the individual power requirement
figure (TABLE 2-2) for each Netra t1 you have installed.
Calculating the Heat To Be Dissipated
To calculate the heat generated by a Netra t1 system so that you can estimate the
heat your cooling system must dissipate, convert the figure for the system’s power
requirement (see “Calculating the Power Requirements for your Netra t1” on page 9)
from watts to BTU/hr. A general formula for doing this is to multiply the figure for
the power requirement by 3.415. For example, the heat that must be dissipated for
the system in:
■ Example A is 92.28 x 3.415=315.14 BTU/hr
■ Example B is 108.4 x 3.415=370.19 BTU/hr

Before following the instructions in this section, make sure you have installed the
Netra t1 system into a rack or cabinet (see Chapter 5).
1. Connect the power cord or cords (see also
FIGURE 6-3 and FIGURE 6-4 in the next
section, “Connecting the Power Cord(s)” on page 50).
2. Connect the system to at least one Ethernet hub. You can connect to a maximum of
two.
3. Connect at least one serial device. For more information, see “Setting up Serial
Connections” on page 52.
If you want to use the Netra t1’s remote monitoring and management facilities,
make sure you use the port labeled Serial A/LOM. For more information about
remote monitoring and management, see Chapter 9.
4. If you intend to configure the Netra t1 system directly from a dumb terminal or a
Sun workstation, insert the serial cable into the DB25 adapter supplied (see
FIGURE 6-1 and FIGURE 6-2).
When you have done this, plug the adapter into the DB25 serial connector on the
terminal or Sun workstation.
5. If you need to connect the Netra t1 system to an external SCSI device, you will
need to use the SCSI cable supplied with that device.
The Netra t1’s external SCSI bus is compatible with narrow (8-bit) or wide (16-bit)
single-ended SCSI devices.
Note – If you are connecting an external SCSI device, make sure that its SCSI ID is
not 0 or 1. The Netra t1’s hard disk drives use these SCSI IDs.
6. Go to Chapter 7 which tells you how to power the system up.
7. For information about the patches you need to apply, see Chapter 8.

Caution – AC-powered Sun products are designed to work with single-phase
power systems having a grounded neutral conductor. To reduce the risk of electric
shock, do not plug Sun products into any other type of power system. Contact your
facilities manager or a qualified electrician if you are not sure what type of power is
supplied to your building.
Caution – Your AC-powered Sun product is shipped with a grounding type (three-
wire) power cord. To reduce the risk of electric shock, always plug the cord into a
grounded outlet.
Chapter 6 Connecting the Cables 51
Setting up Serial Connections
To perform the inital configuration when you install the Netra t1 system, and also
for on-going monitoring and management of the system, you will need to use at
least one of the serial ports on the system’s rear panel. You can connect either or
both serial ports to any of the following devices:
■ A dumb terminal.
For this connection, you can use the standard RJ45 patch cable supplied with the
Netra t1 Model 100/105, but you need to insert one end into the DB25 adapter
also supplied with the Netra t1 system.
■ A Sun workstation.
For this connection, you can use the standard RJ45 patch cable supplied with the
Netra t1 Model 100/105, but you need to insert one end into the DB25 adapter
also supplied with the Netra t1 system.
■ A Terminal Server (or patch panel connected to a Terminal Server).
The pinouts for the Netra t1 system’s serial ports correspond with the pinouts for
the RJ45 ports on the Asynchronous Serial Interface Breakout Cable supplied by
Cisco for use with the Cisco L2511 Terminal Server. For terminals from other
manufacturers, you may need to make your own cross-over (null-modem) cable
(see “Cross-overs for Connecting to a Terminal Server” on page 53).
■ A modem.
For this connection, you can use the standard RJ45 patch cable supplied with the
Netra t1 Model 100/105, but you need to insert one end into the DB25 adapter
also supplied with the system. Do not connect a modem to the Serial A/LOM
port; use the Serial B port. The DTR signal asserted on the Serial A/LOM port
changes to DCD during booting or when control of the port is taken over by the
LOM device, and this can cause modem connections to be lost.
Note – The Serial A/LOM port cannot be used for binary data transfers. To perform
anything other than ASCII transfers, use the port labeled Serial B.
52 Netra t1 User and Administration Guide • June 2000
Cross-overs for Connecting to a Terminal Server
The serial ports on the Netra t1 are DTE ports. If you are connecting them to other
DTE ports, then the cabling between the devices you are connecting to each other
needs to perform a cross-over.
Note – Do not use the Serial A/LOM port for modem connections. The DTE signal
on this port changes temporarily to DCD when the Netra t1’s LOM (Lights-Out
Management) device reports an event on the serial port. This can result in the loss of
a modem connection. If you are connecting the Serial A/LOM port to a Terminal
Server, disable modem control on the Terminal Server port.
The pinouts for the Netra t1’s serial ports correspond with the pinouts for the RJ45
ports on Cisco Terminal Servers. This means, for example, that if you are using a
Cisco L2511 Terminal Server (and you are connecting the Netra t1 system to it using
the Cisco Asynchronous Serial Interface Breakout Cable), you can either:
■ connect the Breakout Cable directly to the Netra t1, or you can
■ connect the Breakout Cable to a patch panel and use the straight-through patch
cable (supplied by Sun) to connect the patch panel to the Netra t1 (see
Note – You do not have to use the Netra t1 with a Cisco Terminal Server. For other
Terminal Servers, check the manufacturer’s documentation to see if the pinouts of
the serial ports on the Terminal Server match the pinouts of the Netra t1’s serial
ports. If they do not, you need to make a cable that takes each pin on one of the
Netra t1’s serial ports to the corresponding pin in the Terminal Server ’s serial port.

Using a DB25 Adapter for Your Serial Link
The pinouts are identical for both of the RJ45 serial ports on the Netra t1 system. To
connect to a UNIX tip session or a vt100 terminal, you need to use either the DB25
(25-Pin DSUB Male to 8-POS RJ45 Female) adapter that is supplied by Sun (part no.
530-2889) with your system, or an alternative adapter that performs the same pin
cross-overs. The Sun-supplied DB25 adapter enables you to connect to any Sun
system. The cross-overs it performs are listed in

The chapter contains the following sections:
■ “Powering Up and Configuring for the First Time” on page 60
■ “Using the Power (On/Standby) Switch” on page 63
What’s Next?
When you have followed the instructions in this chapter telling you how to power
on the system, and when you have booted and logged in, go to Chapter 8 for
information about using different versions of Solaris.
For information about monitoring and managing the Netra t1, see Chapter 9.
For information about Troubleshooting, see Chapter 11.
59
Powering Up and Configuring for the First Time
To perform the initial configuration of the Netra t1 system, set up a serial connection
via the port labeled Serial A/LOM on the Netra t1 (see Chapter 6).
Make sure you have the Netra t1’s power cord or cords connected (see Chapter 6).
Configuring via a Terminal Server
To access the Netra t1 system from a Sun workstation via a Terminal Server, open a
Terminal Session on the Sun workstation, and type:
# telnet <IP address of Terminal Server> <port number>
For example, for a Netra t1 system connected to port 10000 on a Terminal Server
whose IP address is 192.20.30.10, you would type:
# telnet 192.20.30.10 10000
Configuring from a Terminal or Workstation
To access the Netra t1 system from a dumb terminal just set up a connection between
the terminal and the Netra t1 system.
To access the Netra t1 system from a Sun workstation directly connected to the
system, set up the connections between the devices and run a terminal session. Note,
however, that before you can connect to the Netra t1 system’s Serial A/LOM port
from a Sun workstation, you must edit the hardwire: line in your /etc/remote
file. By default, this line looks as follows:
hardwire:\:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D
60 Netra t1 User and Administration Guide • June 2000
You must replace the letter b ( after term/ and before the third colon) with the letter
a, so that the line looks as follows:

Using the Power (On/Standby) Switch
Caution – The power switch (on the rear panel of the Netra t1 system) is not an
On/Off switch, it is an On/Standby switch. It does not isolate the equipment.
The power (On/Standby) switch of the Netra t1 system is a rocker, momentary
switch. It controls only low voltage signals; no high-voltage circuits pass through it.
This means that the main method of connecting or disconnecting power is by
inserting or removing the power supply cord(s). The system contains no integral
circuit breakers. To isolate it, you must break all connections to it. If you do not do
this by removing the power supply cord(s), you must instead open all external
circuit breakers.

Using Different Versions of Solaris
Note – The Netra t1 ships with Solaris 7 (11/99) pre-installed and fully patched. If
you do not intend to alter this configuration of the Netra t1, skip this chapter.
This chapter tells you how to install Solaris 2.6 onto a Netra t1. The instructions
require you to use the bootable Solaris Operating Environment Installation CD 9/99
(part no. 704-6914-10) supplied with the Netra t1.
Although the Netra t1 ships with Solaris 7 pre-installed and patched, this chapter
refers you to the documentation supplied with Solaris 7 and Solaris 8 if you need to
install either of those operating systems yourself (for example, if you install Solaris
2.6 but then decide to upgrade to Solaris 7 or 8). The Solaris 7 and 8 installations are
standard procedures involving no supplementary CD. We recommend you install
Solaris 7 (11/99 or later).
The chapter goes on to tell you which patches you need to apply if you install
Solaris 2.6, 7 or 8 yourself (instead of using the system as configured and patched by
Sun during manufacturing).
The chapter contains the following sections:
■ “Installing Solaris release 2.6” on page 66
■ “Installing Solaris release 7 or 8” on page 68
■ “The Patches You Need” on page 68
65
Installing Solaris release 2.6
This section tells you how to install release 2.6 of the Solaris operating environment
onto a Netra t1 Model 100/105 system.
Note – The Netra t1’s factory-installed software includes the ‘Lights-Out’
Management software. If you install a new operating system and you want to use
the ‘Lights-Out’ Management facilities described in Chapter 9, you must re-install
the ‘Lights-Out’ Management software. This is available on a CD (part number:
X6972A) from your Sun Enterprise Services representative.
▼ To Install Solaris 2.6 from the CDs
Before you begin the installation process, make sure you have the:
■ Two Solaris 2.6 (5/98) CDs (part no. 704-6220-10)
■ Solaris Operating Environment Installation CD 9/99. This CD is supplied with
the Netra t1 (part no. 704-6914-10). It includes the kernel update patch (105181-xx)
you need for running Solaris 2.6 on a Netra t1 system.
For information about what to type when you want to boot from the CD, see “Patch
108620-04: How to Boot from a CD” on page 69.
Note – To make sure all the most recent patches on the Solaris 2.6 (5/98) CDs are
applied, install the entire distribution plus OEM support.
1. Insert the Solaris Operating Environment Installation CD into the CD-ROM drive
and, at the ok prompt, type the following (but refer to the section called “Patch
108620-04: How to Boot from a CD” on page 69):
ok boot cdrom
2. Follow the instructions displayed on the console.
These tell you when to insert the Solaris 2.6 (5/98) CDs.
66 Netra t1 User and Administration Guide • June 2000
▼ To Install Solaris 2.6 from the Network
Note – To make sure all the most recent patches on the Solaris 2.6 (5/98) CDs are
applied, install the entire distribution plus OEM support.
Before following the instructions below, make a note of the MAC address of the
system you are installing Solaris 2.6 onto. This is displayed on the banner that
appears on your console when you boot the system.
1. On another Solaris system, which must be on the same network as the Netra t1
system you are installing Solaris 2.6 onto, create a Solaris 2.6 (5/98) net install
server. Do this by following the instructions supplied with the Solaris 2.6 (5/98)
CDs.
Because the instructions below require you to install software from a second CD (the
Solaris Operating Environment Installation CD) onto the system you are using as the
net install server, you cannot leave the Solaris 2.6 (5/98) CD in the CD drive.
Instead, therefore, you must copy the install image from the Solaris 2.6 (5/98) CD
onto the local disk of the system you are using as the net install server.
2. When the install server setup is complete, remove the Solaris 2.6 (5/98) CD and
insert the Solaris Operating Environment Installation CD.
3. Run the modify_install_server script.
For information about running this script, refer to the documentation provided with
the Solaris 2.6 (5/98) CDs. Running this script with the Solaris Operating
Environment Installation CD inserted updates the net install server with the patches
required for the Netra t1.
4. Register the Netra t1 Model 100/105 with the net install server by running the
add_install_client script on that server.
For more information about running the add_install_client script, refer to the
documentation provided with the Solaris 2.6 (5/98) CD.
5. On the Netra t1 Model 100/105 that you are installing Solaris 2.6 onto, make sure
that the autoboot? environment variable is set to true. To do this, type:
ok autoboot?=true
6. Make sure the Netra t1 Model 100/105 you are installing Solaris onto does not
contain a valid system disk from which to boot. Or, if it does, break to the ok
prompt and type:
ok boot net
Chapter 8 Using Different Versions of Solaris 67
7. Power up the Netra t1 Model 100/105. When you do this, the system will
automatically attempt to boot from the network.
8. Follow the instructions on the console for a standard installation.
For more information, refer to the documentation provided with Solaris 2.6 (5/98).
Installing Solaris release 7 or 8
The Netra t1 system is supplied with Solaris 7 (11/99) already installed and patched.
To re-install Solaris 7 (for example, after having previously installed Solaris 2.6) or to
install Solaris 8, follow the instructions in the documentation provided with your
Solaris 7 or 8 CD. These installations are standard procedures and do not involve
supplementary installation CDs.
If you are installing Solaris 7, we recommend you install the version dated 11/99 or
later.
Note – The Netra t1’s factory-installed software includes the ‘Lights-Out’
Management software. If you install a new operating system and you want to use
the ‘Lights-Out’ Management facilities described in Chapter 9, you must re-install
the ‘Lights-Out’ Management software. This is available on a CD (part number:
X6972A) from your Sun Enterprise Services representative.
The Patches You Need
TABLE 8-1 tells you which patches you need to apply to run the different versions of
Solaris on a Netra t1 Model 100/105. The latest versions of each patch are available
from your local Sun Enterprise Services representative or from SunSolve:
http://www.sun.com/sunsolve
Note – If you are using the factory-installed system software, you do not need to
apply any patches. They have been applied for you already.

Patch 108673-01: Setting Environment Variables
Note – If you have patch 108673-01 applied, you do not need to set any
environment variables. Note that the Netra t1 now ships with this patch already
applied. You only need to follow the instructions below if you do not have patch
108673-01 applied to the operating system.
Patch 108673-01 contains a version of the Sun OpenBoot
specifically for the Netra t1. It is required because the default parameter settings in
versions of the OBP software used on other Sun platforms are not correct for the
Netra t1.
This means that, if you do not have patch 108673-01 applied, you must set certain
OBP parameters manually for the Netra t1. It also means that, if you use the
set-defaults command after setting these parameters manually, you must set
them manually again. (The set-defaults command returns the OBP parameters to
their defaults. Unless you have patch 108673-01 applied, these defaults will not be
correct for the Netra t1.)
The OBP parameters are stored in NVRAM on the motherboard. To make sure they
are correct for a Netra t1 system that does not have patch 108673-01 applied, do the
following:
1. Return the OBP parameters to their standard settings by typing:
ok set-defaults

This chapter describes the Netra t1 system’s remote monitoring and management
facility. It contains the following sections:
■ “What You Can Use the ‘Lights-Out’ Management (LOM) Facility For” on page 76
■ “How the LOM Device Sends its Event Reports” on page 77
■ “Interrogating the LOM and Using it to Power Up or Reset the System” on

■ “Utilites Associated with the LOM Device” on page 86
■ “The System’s Front and Back Panel LEDs” on page 87
■ “The Fans Monitored by the LOM Device” on page 88
75
What You Can Use the ‘Lights-Out’ Management (LOM) Facility For
The Netra t1 includes a management facility which allows you to detect and respond
quickly to problems with the Power Supply Unit (PSU) or fans. It is particularly
useful for monitoring servers remotely that are deployed in a “lights out”
environment. But you can also use it to perform quick onsite management tasks via
a local serial connection.
This management facility is provided by a device on the Netra t1’s motherboard
called the Lights-Out Management (LOM) device and by software that is preinstalled on your system during manufacturing.
Note – If you install new system software onto the Netra t1 and you want to
continue using the Lights-Out Management facility, you must re-install the LOM
software. A CD containing the software is available from your Sun Enterprise
Services representative (part number: X6972A).
You can use the LOM facility to:
■ Monitor the status of the power supply, fans, fault LED and alarms even when the
system is powered down.
■ Power the system up and down.
■ Turn a Fault LED on (for example, to enable you to identify a particular system in
a rack containing a number of Netra t1s).
You can also configure the LOM device on the Netra t1 to perform an automatic
system restart in the event of a lock-up.
76 Netra t1 User and Administration Guide • June 2000
How the LOM Device Sends its Event Reports
The LOM device monitors the status of the fans and the power supply even when
the system is powered down (the LOM device operates on standby power). If it
detects a fault, it turns on the Fault LED on the system’s front and rear panels and
stores a report in an event log which resides in memory on the LOM device itself.
What it does next depends on whether the operating system is running with a
daemon called lomlited enabled:
■ If your Netra t1 system is running the factory-installed system software, then the
Lights-Out Management software, including the lomlited daemon, is fully
installed and enabled.
■ If you are not running the factory-installed system software (but are running
another configuration of Solaris), then you need to re-install the Lights-Out
Management software from a CD (part number: X6972A) that is available from
your Sun Enterprise Services representative.
When the Operating System is Running and the lomlited Daemon is Installed and Running
When the operating system is running and the lomlited daemon is enabled, the
LOM device is monitored by the lomlited daemon. This daemon sends LOM event
reports to syslogd giving them the identifier string lomlited. syslogd handles
them in the way it is configured to handle event reports (by default, it sends them to
the console and stores them in /var/adm/messages).
The lomlited daemon is started by an rc script. The daemon is stored in /etc/
init.d.
When the lomlited Daemon is Not Running
The lomlited daemon does not monitor the LOM device when:
■ The operating system is not running (for example, when the ok prompt is
displayed on your console).
■ You have disabled the lomlited daemon.
■ You have installed new operating system software (over the factory-installed
system software) but have not manually re-installed the LOMlite software.
Chapter 9 Monitoring and Managing the System 77
In any of these circumstances, when the lomlited daemon is not running and an
event affecting the fans or power supply occurs, the LOM device takes control of the
Serial A/LOM port and sends an event report onto that port. When it has sent the
report, the LOM device relinquishes control of the serial port. Note that this can
interfere with communication on the Serial A/LOM port (see note below).
Note – LOM reports that occur when the lomlited daemon is not running can
interfere with communication on the Serial A/LOM port. If you do not have the
lomlited daemon installed and enabled then, to prevent the LOM from
interrupting serial communication, either use the Serial B port as your console port
or turn off LOM event reporting (see “Stopping the LOM from Sending Reports to
the Serial A Port When the Daemon is not Running” on page 78”).
Capturing LOM Event Reports Passively on the Serial A/LOM Port
To monitor LOM events as they occur, keep a terminal connected to Serial Port A.
For information about setting up serial connections to the Netra t1, see Chapter 6.
For information about using LOM commands to interrogate the LOM device, see
“Interrogating the LOM and Using it to Power Up or Reset the System” on page 79.
Stopping the LOM from Sending Reports to the Serial A Port When the Daemon is not Running
LOM reports that occur when the lomlited daemon is not running can interfere
with information you are attempting to send or receive on the Serial A/LOM port.
If you do not have the LOM software installed or you have disabled the lomlited
daemon, you might want to stop the LOM device from sending reports to the Serial
A/LOM port.
To do this, use the lomctl utility stored in the /usr/bin directory.
To turn off reporting to the serial port, type:
# lomctl serialeventsoff
