1.5 Site Preparation
This section contains information about the following system and site requirements
for the Sun Fire B1600 blade system chassis:
■ Section 1.5.1, “System Cooling Requirements” on page 1-8
■ Section 1.5.2, “Operating Power Limits and Ranges” on page 1-12
■ Section 1.5.3, “Estimating Power Consumption” on page 1-12
1.5.1 System Cooling Requirements
This section provides the general environmental parameters and airflow
requirements for the Sun Fire B1600 blade system chassis.
Note – The Sun Fire B1600 blade system chassis uses front-to-back forced air
cooling.

Recommended Environment Parameters
Your environmental control system must provide intake air for the server which
complies with the limits specified in “General Environmental Parameters” on
page 1-8.
To avoid overheating, do not direct warmed air:
■ towards the front of the cabinet or rack
■ towards the server access panels
Note – When you receive your system, leave it in the shipping crate at its final
destination for 24 hours in the environment in which you will install it. This is to
prevent thermal shock and condensation.
The operating environmental limits in
TABLE 1-2 reflect what the systems have been
tested to, in order to meet all functional requirements. Operating computer
equipment in extremes of temperature or humidity increases the failure rate of
hardware components. To minimize the chance of component failure, use the server
within the optimal temperature and humidity ranges.
Ambient Temperature
An ambient temperature range of 21˚C to 23˚C is optimal for system reliability. At
22˚C it is easy to maintain safe relative humidity levels. Operating in this
temperature range provides a buffer in the event of the environmental support
systems failing.
Ambient Relative Humidity
Ambient relative humidity levels between 45% and 50% are the most suitable for
data processing operations in order to:
■ prevent corrosion
■ provide an operating time buffer in the event of environmental control system
failure
■ help avoid failures caused by the intermittent interference from static discharges
that occur when relative humidity is too low.
Electrostatic discharge (ESD) is easily generated and less easily dissipated in areas
where the relative humidity is below 35%, and becomes critical when levels drop
below 30%.
1-10 Sun Fire B1600 System Chassis Hardware Installation Guide • August 2003
1.5.1.2 Airflow Requirements
The Sun Fire B1600 blade system chassis has been designed to function in a natural
convection airflow when mounted in a rack or cabinet and uses front-to-back forced
air cooling. To meet the declared environmental specification follow these
guidelines:
■ The Sun Fire B1600 blade system chassis uses PSU fans that can achieve a
maximum airflow of 160cfm in free air. Ensure that there is sufficient airflow
through the rack or cabinet.
■ The rack or cabinet in which the system chassis is mounted must provide inlet air
at the front of the system chassis. The airflow exhausts horizontally from the PSU
and SSC modules located at the back of the system chassis and must be able to
leave the cabinet.
■ Inlet and exhaust ventilation must both have a minimum open area of
■ The use of perforated or solid door panels must allow adequate airflow to the
2
22in
(142 cm2) for each system chassis.
system chassis when the cabinet doors are closed.
1.5.1.3 Estimating the Heat Dissipation
To estimate the heat generated by a Sun Fire B1600 blade system chassis convert the
figure for the system’s power consumption from watts to BTU/hr.
The formula to convert from watts to BTU/hr is to multiply the power in watts by
3.415. For example:
total power consumption of blades + total power consumption of SSCs + total power
consumption of PSUs x 3.415 = xxxxx BTU/hr
For power consumption figures for the SSC, the PSU and blades, see “Estimating
Power Consumption” on page 1-12
Note – Do not install multiple Sun Fire B1600 blade system chassis in a four-post
rack or cabinet unless your cooling system is capable of dissipating in excess of the
total thermal load. For example:
(5 x 700W each system) x 3.415 = 11952.5 BTU/hr

protrude beyond the front face of the system chassis to enable proper airflow.
Access to the front and back of the Sun Fire B1600 blade system chassis is required
for installation and system maintenance.
Note – If you are installing the system chassis into a cabinet that has a door, you
might need to swing the door back 180 degrees, or remove the door altogether.
2-2 Sun Fire B1600 System Chassis Hardware Installation Guide • August 2003
2.3 Rack and Floor Loading
The rack or cabinet must be capable of supporting a static load of 99 lb (45kg) for
each fully configured Sun B1600 blade system chassis. Dynamic load considerations
are subject to site location and application. You must account for the weight of any
cables attached to systems within the rack, as well as additional hardware installed
within the rack (power boxes, and so on).
See your manufacturer’s loading guidelines to avoid overloading the rack or cabinet.
Check the maximum floor loading weight for the installation area before calculating
the number of system chassis to install in a rack or cabinet.
2.4 Rack and Cabinet Safety
Racks or cabinets that contain Sun Fire B1600 blade system chassis must be anchored
to the floor or to adjacent frames, using the manufacturer’s instructions.
Free-standing racks or cabinets with a footprint of less than 23.6in. x 23.6in.
(600mm x 600 mm) are likely to be unstable and should be treated with caution.
Where several system chassis are fitted in a rack or cabinet, only one of them should
be withdrawn for service at any one time.
See the Sun Fire B1600 Blade System Chassis Compliance and Safety Manual for further
safety information.
Caution – If the system chassis is installed in a closed or multi unit rack assembly,
the operating ambient temperature of the rack or cabinet environment might exceed
the room ambient. Ensure that rack environment ambient temperature does not
exceed 95˚ F (35˚ C).
Caution – Mounting of the system chassis in a rack or cabinet should be such that a
hazardous condition is not created due to uneven mechanical loading or weight
distribution.

4.3 Removing and Installing a Switch and System Controller (SSC)
Use the procedures in this section to remove and install an SSC. These are optional
procedures to enable you to familiarize yourself with the mechanism, or to check the
SSC Serial Number.
Note – The procedures contained in this section assume that the system chassis is
not connected to the network and is not powered up. See the Sun Fire B1600 Blade
System Chassis Administration Guide for instructions on removing an SSC from a
networked and powered system chassis.
4.3.1 Chassis Supplied With Only One SSC
If you have purchased a chassis containing only a single SSC, then the module in
slot SSC1 will be an SSC filler module (see
enclosure; it contains no functioning system hardware and you cannot connect a
serial cable or any network cables to it (it has no connectors).
Note – If you are removing a filler panel and replacing it with a new SSC, make sure
the currently installed SSC is using release 1.2 (or later) of the System Controller
firmware. (Also, if the module you are installing as a redundant SCC is not a new
one but is taken from another chassis and does not have release 1.2 firmware
installed on it, you need to upgrade it on the old chassis before installing it as a
redundant SSC.) Release 1.2 is the first firmware release to support failover (in other
words, to support the ability of two System Controllers to monitor each other’s
health, and of the standby System Controller to take over from the active one in the
event of a critical failure).
FIGURE 4-13). This is an empty metal
For full instructions about replacing an SSC filler module with a new SSC module,
and about upgrading the System Controller firmware on an SSC, refer to the Sun Fire

5.3 Cable Requirements for 1000BASE-T and 10/100BASE-TX Connections
This section provides details of the 1000BASE-T and 10/100BASE-TX cable
requirements when connecting to a Sun Fire B1600 blade system chassis.
5.3.1 1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T connections, providing that all four wire pairs are connected.
However, for all critical connections or any new cable installations, use
Category 5E (enhanced Category 5) cable. The Category 5E specification includes
test parameters that are only recommendations for Category 5. Therefore, the first
step in preparing existing Category 5 UTP cable for running 1000BASE-T is a simple
test of the cable installation to confirm that it complies with the IEEE 802.3ab
standards.
5.3.1.1 Cable Testing for Existing Category 5 Cable
Installed Category 5 UTP cables must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss, skew and Equal-Level Far-End Crosstalk (ELFEXT).
These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”
Chapter 5 Connecting and Managing Cables 5-5
5.3.2 Cable Requirements for 10/100BASE-TX Devices
The data ports on the SSC are designed to operate at an optimal speed of 1000 Mbps
but can be connected to 10 or 100 Mbytes/sec devices. The SSC also includes a
10/100BASE-TX management port. For 10/100BASE-TX connections, twisted-pair
cable can have two or four pairs of wires. Each wire pair is two different colors. For
example, one wire might be red, and the other red with white stripes. When
connecting the SSC to a device at 10 or 100 Mbytes/sec, use unshielded twisted-pair
(UTP) cable with RJ-45 connectors at both ends. For 100BASE-TX connections,
Category 5 cable is required. For 10BASE-T connections, Category 3, 4 or 5 cable can
be used.
Note – Twisted-pair cables must not exceed 100 meters (328 feet) in length.
Note – When connected to a shared collision domain (such as a hub with multiple
workstations), switch ports must be set to half-duplex mode and back pressure flow
control must be disabled to avoid propagating jamming packets throughout the
segment.
5.4 Attaching the Connector Cables
You must connect the power cords to the PSUs before you attach the remaining
cables:
■ RJ-45 10/100/1000BASE-T data network connectors
(see Section 5.5, “Connecting to the 10/100/1000BASE-T Data Network Ports” on
page 5-7 for further information)
■ RJ-45 10/100BASE-T network management connectors
(see Section 5.6, “Connecting to the 10/100BASE-T Network Management Ports”
on page 5-10 for further information)
■ RS232 serial connectors (see “Connecting the RS232 Serial Port to Different
Devices” on page 6-1 for further information)
Attach the RJ-45 connectors by inserting the connector into the relevant port until
the connector clicks in place.
5-6 Sun Fire B1600 System Chassis Hardware Installation Guide • August 2003
The SSC is designed to connect to IEEE 802.3ab compliant devices. For most
applications, the external ports on the SSC will be connected to other switches in the
network backbone. It might also be connected directly to Gigabit Ethernet network
cards in PCs or servers.
Caution – Do not connect a telephone jack connector to any RJ-45 port. This can
damage the switch. Instead, use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards, or local national wiring or electrical regulations.

5.7 Managing Cables for Multiple System Chassis
A Sun Fire B1600 blade system chassis that uses every available connection has
22 cables (including power cords) attached to the back of the system. When multiple
system chassis are installed within the same rack you must use effective cable
management to avoid blocking airflow through the system chassis.
Check that:
■ Cables are of an adequate length
■ There is adequate clearance at the back of the system chassis
■ The cabling from multiple system chassis does not block the back vents of any
system chassis that is installed beneath them
Cable management rings are attached to the module ejector handles on each PSU
and SSC. Use each ring to gather the cables from each module and to keep them
clear of the back system vents (
FIGURE 5-8).

Caution – Failure to keep the vents at the back of the system chassis clear might
cause the system chassis to overheat and lead to system shutdown.
5.8 What to Do Next
See Chapter 6 for details of how to connect the Serial Port to different types of device
such as a:
■ Terminal server
■ VT100 terminal or Sun Workstation
■ Terminal that has a 9-pin adapter
■ Modem

CHAPTER
6
Connecting the RS232 Serial Port to Different Devices
To perform the initial configuration when you have installed and applied power to
the blade system chassis, you must either set up a serial connection to SSC0 or you
must set up a DHCP server to perform the IP configuration of the chassis’ active
System Controller automatically. If you set up a DHCP server to do this, you can
then telnet into the active System Controller to set up the chassis for the first time.
For information about configuring a DHCP server to enable you to connect to the
chassis’ active System Controller for the first time over a telnet instead of a serial
connection, see the Sun Fire B1600 Blade System Chassis Software Setup Guide.
Note – When both SSCs in the chassis are powered and working normally and
neither is damaged, by default SSC0 contains the active System Controller and SSC1
contains the standby System Controller. This means that, to set up the chassis for the
first time using a serial connection, you need a serial connection to at least SSC0.
However, for day-to-day operation of the blade system chassis, we recommend you
set up serial connections to both SSCs. This ensures that, if the active SSC fails for
any reason, you do not lose serial connectivity to the chassis.
This chapter contains the following sections:
■ Section 6.1, “Serial Port Pin Numbers” on page 6-2
■ Section 6.2, “Connecting to a Terminal Server” on page 6-3
■ Section 6.3, “Connecting to a VT100 Terminal or a Sun Workstation” on page 6-4

6.2 Connecting to a Terminal Server
For this connection, you can use the standard RJ-45 patch cable and DB-25 adapter
supplied with the system chassis.
The serial port is a DTE port. You must be aware that if you are connecting a SSC’s
serial port to another DTE port - the pinouts for the serial ports on the SSCs
correspond with the pinouts for the RJ-45 ports on Cisco terminal servers. This
means that if you are using a Cisco AS2511-RJ terminal server you can:
■ Connect a rollover cable directly to the Sun Fire B1600 blade system chassis.
■ Connect a rollover cable to a patch panel and use a straight-through patch cable
to connect the patch panel to the Sun Fire B1600 blade system chassis (see
FIGURE 6-2).
Note – You do not have to use a Cisco terminal server. For other terminal servers,
see the manufacturer’s documentation to confirm whether the pinouts of the serial
ports on the terminal server match the pinouts of the Sun Fire B1600 system chassis.
If they do not, write down which pins on the terminal server’s serial ports carry the
signals listed in the right-hand column in
taking each of the pins on either SSC’s serial port to the correct pin on the terminal
server’s serial port.
