1.4 Installing the Cable Management Arm
This section contains the following topics:
■ “Installing the CMA–Lite” on page 1-22
■ “Installing the CMA–800” on page 1-23
The purpose of a cable management arm is to support and protect cables when a
system slides into or out of a cabinet.
Two cable management arm solutions are offered: CMA-Lite and CMA-800. The
optimum choice of CMA is dependant upon the available depth in the cabinet and
the quantity or type of cable to be supported. Use the CMA-Lite if the larger CMA800 management arm does not fit your cabinet.
Threaded holes for attaching the CMA are provided on the rear of the system
(

1.7 Connecting Consoles to the System
Controller
This section contains the following topics:
■ “Connecting the Initial Administrative Console” on page 1-30
■ “Connecting the Administrative Console” on page 1-32
The system controller (SC) is responsible for providing the Lights-Out Management
(LOM) functions, which include power on sequencing, sequencing module power-on
self-tests (POST), environmental monitoring, fault indication and alarms.
The LOM command line interface and the Solaris/OpenBoot™ PROM console are
accessed by connecting an administrative console to either serial port A or the
10/100 LOM Ethernet port. The administrative console can be any external input
device (laptop computer or workstation) connected to either of these ports.
Serial port A is used to connect directly to an ASCII terminal or a network terminal
server (NTS) using a command line interface. This port is used for the initial
administrative console. It is used to modify the default system controller settings
(usually so that the 10/100 LOM Ethernet port can be used as an administrative
console). The configuration of Serial port A cannot be changed.
The 10/100 LOM Ethernet port is used to connect the system controller to the
network. This port is preconfigured as follows:
■ System controller configured to be on a network
■ System controller Ethernet configured for dynamic host configuration protocol
(DHCP).
■ No pre-configured system controller Ethernet IP address, Gateway, DNS domain,
DNS servers
1.7.1 Connecting the Initial Administrative Console
For the initial configuration, connect Serial A port to the serial port on any of the
following devices:
■ ASCII terminal
■ Sun workstation
■ Terminal server (or patch panel connected to a terminal server)
Note – If the IP address assigned to the 10/100 LOM Ethernet port by DHCP is
known, the 10/100 LOM Ethernet port can be accessed without the Serial A port.
1-30 Sun Fire V1280/Netra 1280 Systems Installation Guide • December 2003
1. Connect the administrative console to the Serial A port.
The Serial A port is a DTE (data terminal equipment) port. An adapter, cross-over or
null modem cable is required to connect the Serial A port to another DTE port. For
Serial A port connector pinouts and adaptor information, see “LOM Serial Ports” on
page A-5).

Chapter 1 Physical Installation 1-33
1.11 Installing Additional Hardware
Do not install additional hardware until the initial factory configuration has been
completely installed, the system has been powered on, and POST has been
completed successfully. This makes it easier to diagnose conflicts that might be
caused by additional installations.
Caution – To avoid damaging boards when installing CPU/Memory boards refer to
the Sun Fire V1280/Netra 1280 Systems Service Manual for instructions.
Caution – During initial installation, turn off the power at the circuit breakers
before removing or replacing system hardware. Refer to the installation guide of the
additional hardware for any additional instructions.
Note – For optimum performance, use only PCI cards and associated drivers that
are qualified by Sun Microsystems for use on the Sun Fire V1280/Netra 1280
systems. It is possible for interactions to occur between cards and drivers on a
specific bus that might lead to potential system panics or other negative outcomes if
the card/driver solution is not qualified by Sun Microsystems.
For an updated listing of qualified PCI cards and configurations for the system,
contact your Sun authorized sales representative or your service provider. For
additional information refer to:
http://www.sun.com/io
1.12 Installing Additional Peripheral Devices
When you add additional storage devices, refer to the Rackmount Placement Matrix,at
http://docs.sun.com, for the mounting hole numbers of the mounting screws
for Sun Microsystems disk arrays, other storage trays, and devices.
Unless otherwise specified in the Rackmount Placement Matrix, mount the heaviest
subassemblies at the lowest available opening to minimize the effects of a top-heavy
system in the event of an earthquake.

A.1 PCI Slots
Sun Fire V1280/Netra 1280 systems provide six PCI slots. The PCI slots are labeled 0
through 5. When viewing the rear of the system, slot 0 is on the left and slot 5 is on
the right. The PCI slots are not hot swappable. All slots are half length.
PCI slots 0-4 support 33-MHz cards of 5V and universal type. Slot 5 supports 33MHz or 66-MHz cards and only 3V3 or universal cards. The connector type prevents
3V3 only cards from fitting to a 5V slot and vice versa. All slots are 64 bit.
If a 33-MHz only card is inserted into slot 5, the PCI transfers to the internal SCSI
disk controller will be limited to 33 MHz. This might reduce the performance on
both the internal and external ports.
