JG608A HP FlexFabric 11908-V Switch Chassis BJNGA-AC0003
IMPORTANT:
For regulatory identification purposes, HP FlexFabric 11900 switches are assigned regulatory model
numbers (RMN). These regulatory numbers should not be confused with the marketing name, for example
HP FlexFabric 11908-V Switch Chassis, or product code, for example JG608A.
Safety recommendations
To avoid possible bodily injury and equipment damage, read all safety recommendations carefully
before installation. Note that the recommendations do not cover every possible hazardous condition.
General safety recommendations
•Keep the chassis clean and dust-free.
•Do not place the switch on a moist area, and avoid liquid flowing into the switch.
•Make sure the ground is dry and flat and anti-slip measures are in place.
•Keep the chassis and installation tools away from walk areas.
•Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get
caught in the chassis when you install and maintain the switch.
Electricity safety
•Clear the work area of possible electricity hazards, such as ungrounded power extension cables,
missing safety grounds, and wet floors.
•Locate the emergency power-off switch in the room before installation so you can quickly shut power
off when an electrical accident occurs.
•Unplug all external cables, including power cords, before moving the chassis.
•Do not work alone when the switch has power.
•Never assume that power has been disconnected from a circuit. Always check.

2
Handling safety
CAUTION:
Do not hold the handle of the fan tray, power supply, or back cover of the chassis, or the air vents of
chassis. Any attempt to move the switch with these parts mi
g
ht cause equipment dama
g
e and even bodil
y
injury.
When you move the switch, follow these guidelines:
•Remove all external cables, including the power cords, before moving the chassis.
•Moving the chassis requires at least two persons, and you can use a mechanical lift as needed.
•Lift and put down the chassis slowly and never move suddenly.
•Hold the handles on the chassis.
ESD prevention
To prevent the electric component from being damaged by ESD, follow these guidelines:
•Ground the switch correctly. For how to ground your switch, see "Installing the switch."
•Always wear an ESD wrist strap and make sure it is well grounded when installing FRUs. For how
to use an ESD wrist strap, see "Installing FRUs."
•Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•Put cards away in ESD bags for future use.
Laser safety
W
ARNING!
Do not stare into any fiber port when the switch has power. The laser li
g
ht emitted from the optical fiber
might hurt your eyes.
Examining the installation site
The HP FlexFabric 11900 switches must be used indoors. To ensure normal operation and long service life
of your switch, the installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power supplies, and all other
components. Additionally, the floor loading plan must also consider system expansion, such as adding
more cards. For more information, see "Appendix A Chassis views and technical specifications."

3
Temperature
CAUTION:
To avoid short circuits, if condensation appears on the chassis when you move it to a high-temperature
environment, dry the chassis before powering it on.
To ensure normal operation of the switch, make sure the room temperature meets the requirements
in Table 2.

e
Operating temperature 0°C to 45°C (32°F to 113°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table 3.
•Lasting high relative humidity tends to cause poor insulation, electricity creepage, mechanical
property change of materials, and corrosion of metal parts.
•Lasting low relative humidity is likely to result in loose screws due to washer contraction, and even
ESD, which causes the circuits to fail.

Operating humidity 10% to 95%, noncondensing
Storage humidity 5% to 95%, noncondensing
Cleanness
Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal

EMI
All EMI sources, from outside or inside of the switch and application system, adversely affect the switch
in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation,
or common impedance (including the grounding system) coupling. To prevent EMI, take the following
actions:
•Take measures against interference from the power grid.
•Use a grounding system and lighting protection system for the switch separate from those for other
electric equipment, and keep them far away as possible.
•Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Grounding
Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD
is essential to the operating reliability of your switch.
Make sure the resistance between the chassis and the ground is less than 1 ohm.
Power
Perform the following tasks to meet the power requirements:
1. Calculate the system power consumption.
The system power consumption varies by card type and density. For more information about
system power consumption calculation, see "Appendix A Chassis views and technical
specifications."
2. Select power supplies and identity the number of power supplies.
The total maximum output power of all power supplies must be higher than the system power
consumption. For more information about available power supplies, see "Appendix B FRUs and
compatibility matrixes."
3. Verify that the power system at the installation site meets the requirements of the power supplies,
including the input method and rated input voltage.
Cooling
Plan the installation site for adequate ventilation.

5
•Leave at least 10 cm (3.94 in) of clearance at the inlet and outlet air vents.
•The rack for the switch has a good cooling system.
•The installation site has a good cooling system.
•Verify that the airflow design of the chassis meets the airflow design of the installation site.

Confirming installation preparations
Before you install the switch, verify that:
•You have read "Preparing for installation" carefully and the installation site meets all the
requirements.
•If you are rack-mounting the switch, verify that the following conditions are met:
{A 19-inch rack is ready for use. For how to install a rack, see the rack installation guide.
{The rack is sturdy and securely grounded.
{No debris exists inside or around the rack.
{Choose a correct rack mounting position for the switch. Make sure the heaviest device is placed
at the bottom of the rack.
{The total height of the switches to be installed is no higher than the available installation height
of the rack, and enough clearance is reserved for cable routing.
•If you are mounting the switch on a workbench, make sure the workbench is sturdy and securely
grounded.
•The switch is ready for installation and has been carried to a place near the installation site and
convenient for moving.
Installing the switch in a 19-inch rack
Attaching slide rails and cage nuts to the rack
Installing slide rails
If the rack has slide rails, skip this section.
Before you attach slide rails to the rack, verify that the following conditions are met:
•The slide rails can support the weight of the switch. For the weights of the HP FlexFabric 11900
switches, see "Appendix A Chassis views and technical specifications."
HP recommends that you order the HP X421 A-Series Chassis Universal 4-Post Rack Mounting Kit
(JC665A). For more information about the kit, see "Appendix B FRUs and compatibility matrixes."
•If you install the switch in an enclosed cabinet, make sure the distance between the front rack posts
and the front door is at least 100 mm (3.94 in) for installing cable management brackets, and the
distance between the front rack posts and the rear door is at least 660 mm (25.98 in) for the chassis
with cards installed.

7
•To ensure rack stability, install the slide rails to the lowest possible position when installing a single
switch on the rack. To install multiple switches on the rack, mount the heaviest switch at the bottom
of the rack.
•Identify the chassis and slide rail positions for the switch. For the height and other specifications, see
"Appendix A Chassis views and technical specifications."
Slide rail installation varies with rack type. This section uses the slide rails in the HP rack mounting kit
(JC665A) as an example.
To install a slide rail:
1. Read the signs on the slide rail (see Table 6) to avoid making a mistake.

2. Mark the position on the rack for installing the slide rail:
a. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in Figure 3.
b. Each rack post requires six screws to attach the slide rail. Mark the uppermost square hole and
lowermost square hole for installation.
c. Mark the square holes at the same height on the other three rack posts.

NOTE:
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the other two
are standard installation holes. You can distin
g
uish them by the space between each two holes. The
space between a standard installation hole and an auxiliary installation hole is wider than that
between two adjacent standard installation holes.
