Preparing for Installation

Install the equipment in a restricted access location.

Set up a local console (serial-port monitor and USB key-

board or a computer with terminal emulation) for con-

figuring or troubleshooting the software installation.

Verify the installation location meets the electrical power

requirements. FlashBlade//S requires four C20,

20A/250V power outlets.

Install any additional blades, DFMs, and DFM blanks

after mounting the chassis to reduce weight. The

FlashBlade//S with 7 blades and 3 blanks without DFMs

weighs 80 kg (176 lb). Use a mechanical lift or 4 or more

people to lift the chassis.

Make sure the rack can support the weight of all installed

equipment, including cables, bezel, and rails—approx-

imately 100 kg (220 lb) for each FlashBlade//S chassis—

and the weight is within the floor loading limit.

Save all provided tools, cartons, and packing material in

case return shipment to Pure Storage is necessary.

Prior to unpacking, inspect packages for shipping dam-

age. If there is damage, photograph it and contact Pure

Storage Technical Services before proceeding.

Have all necessary cables available.

Mount the chassis to the rack within 3 m (9.85 ft.) of the

network connection switches or panels.

Verify the installation environment:

lIs within the operating temperature range of 5°C-35°C

when the rack is fully populated.

lDoes not have airflow ducts aimed directly at any

chassis.

The installation shall require all of the following:

lThe building installation shall provide a means for con-

necting to protective earth, and

lThe equipment is to be connected to that means, and

lA service person shall check the socket-outlets provid-

ing power to the equipment, provide a connection to

the building protective earth. If not, the service person

shall arrange the installation of a protective earthing

conductor from a separate protective earthing terminal

to the protective earth wire in the building.

1. Unpack the FlashBlade//S Components

Remove the overpack box and verify the FlashBlade//S package contains the items shown in Figure 1.

2. Install the Rails

The chassis includes two rails, labeled right and left. The

rails have locating pins (for square- and round-hole

racks) or positioning studs (visible if you unscrew and

remove the locating pins for threaded-hole racks) that

align with the holes in the rack.

1. (Square-hole racks only) Install the #10-32 cage

nuts (included in Rail Kit) on the back side of the

front rack post, as shown in Figure 2. The cage nut

insertion tool is not provided.

For round-hole racks, use clip nuts (not provided)

instead of cage nuts.

2. Install one of the two rails (the installation order does

not matter) by pulling the spring-loaded lever back

and inserting the locating pins or positioning studs in

the front mounting post at the desired height.

Release the lever once the rail is in place. See Fig-

ure 3.

3. Extend the rear of the rail until the locating pins or

positioning studs reach the rear mounting post, and

press the rail into the rear post until the latch

engages. See Figure 4 (left rail shown).

4. (All rack types) Secure the rear of each rail to the

rack with the screws provided in the Rail Kit. One

screw is provided for the rear of each rail. Use the

second or fifth hole up from the bottom of each rail

(shown going into the fifth hole). See Figure 4.

5. Repeat the previous steps to install the second rail.

Make sure to install the rear of each rail into the post

holes that are at the same height as the holes being

used on the front post. Otherwise, the chassis might

slide off the rails causing personal injury and dam-

age to the chassis.

Figure 4. Installing a Rail (Rear Post)

3. Mount the Chassis into the Rack

Remove the clear protective film on the top sur-

face of the chassis before installing into the

rack.

To avoid injury or damage to the system, do

not insert hands or fingers into the empty drive

bays.

1. Use a mechanical lift to raise the chassis to the

desired height in the rack.

2. Set the rear of the chassis onto the rails and

remove the rear handles while using the mech-

anical lift to support the front of the chassis.

To remove a handle, pull the plunger and slide

it downward. See Figure 5.

3. Continue to slide the chassis into the rack until

you have a two-inch gap between the middle

handles and the rack.

Remove the middle handles while using the

mechanical lift to support the front of the

chassis. See Figure 6.

3. Mount the Chassis into the Rack (Cont'd)

4. Continue to slide the chassis into the rack until

you have a two-inch gap between the front

handles and the rack.

Remove the front handles while using the

mechanical lift to support the front of the

chassis. See Figure 7.

5. Slide the chassis completely into the rack and

verify the chassis ears are flush with the front

of the rack.

6. Secure the chassis ears to the front of the rack

post with the two screws provided in the Rail

Kit.

Open the slam-latches on the chassis front

panel and thread the screw through each

slam-latch hole that lines up with the cage nuts

previously installed in the rack posts.

Use the supplied Phillips screw driver to

tighten the screws. See Figure 8.

7. Close the slam-latches.

5. Install DirectFlash Modules

DirectFlash Modules (DFM) must be installed into the slot in sequen-

tial order (1-2-3-4). Each blade must have the same number of DFMs

installed. See Figure 11.

Locate the boxes with DFMs and prepare for installation.

Make sure all unused slots are filled with blanks.

Working with one DFM box at a time:

1. Open the front latch on the drive fully, then slide the DFM into the slot

and close the latch as you seat the module. See Figure 12.

2. Continue populating the remaining slots with the DFMs in the box, 1

per blade.

3. Make sure the drive module front panels are flush with the chassis

front panel. Check the latch on each module is engaged by pulling

gently on it until you feel resistance.

4. Repeat the previous steps for the remaining boxes of DFMs.

5. Install drive blanks in any unused drive slots to ensure adequate air-

flow. The drive blanks do not have a latching mechanism.

6. (Optional) Use the Torx T10 screw driver included in the Accessory

Kit box to lock each DFM into its blade slot.
