Read all the safety and health information in these instructions.
Failure to follow instructions and properly set up, use, and care for this
product can increase the risk of serious injury or death, or damage to the
device or devices. See the Lenovo ThinkSystem D4390 Direct Attached Storage
Hardware Installation and Maintenance Guide for full installation and
configuration information.
Introduction
Read this section before beginning any procedure. The following text provides
safety precautions to follow when installing the product.
Safe handling
- An empty enclosure can weigh up to 45 kg (100 lb). Use only approved lift handles to lift the chassis.
- A fully populated enclosure weighs 118 kg (260 lb). Do not attempt to lift the enclosure when populated with drives. Use appropriate lifting methods.
Caution: When installing the D4390 in a rack, please install it at the
bottom of the rack due to the center of gravity concern. To enhance rack
cabinet balance, make sure to secure the rack cabinet to the floor with
stabilizer. If you have multiple D4390 enclosures to be installed in a rack,
start from the bottom up. When there are multiple D4390 enclosures installed
in a rack, make sure you pull out only one D4390 enclosure at a time to
service the drives. DO NOT pull out multiple D4390 enclosures at the same time
to avoid the rack being tipped over.
Caution: Due to product acoustics it is recommended that users wear ear
protection for any prolonged exposure.
ESD precautions
It is recommended that you fit and check a suitable anti-static wrist or ankle
strap and observe all conventional ESD precautions when handling plugin
modules and components. Avoid contact with backplane components and module
connectors, etc.
Preparation
Before you begin
Make sure the site where you intend to set up and use your D4390 system has
the following:
-
Standard power from an independent source or a rack power distribution unit with a UPS.
-
Host computer with the correct firmware, BIOS, and drivers.
Contact your supplier for the correct software levels. -
Check the cooling space: ensure thermal dissipation space is enough.
-
The enclosure is designed to fit in standard IEC 19” wide rack with 1100mm depth.
-
Ensure at least 1.5 m (5 ft) clearance in front of the rack (the cold aisle). This allows to fully pull out the chassis without obstruction.
Installation
Mounting the system into a rack
Please refer to CMA flyer for the proper CMA installation.
Caution: Please do apply Loctite® or Nylok® blue patch to the screws to
avoid possible safety risk before relocating the screws to adjust the rail kit
range, if you must adjust the rail kit range. Please refer to Hardware
Installation & Maintenance Guide for more details.
Rail kit installation
- Remove the inner rails from the kit. See Figure 1.
- Install the inner rails onto the chassis. See Figure 2.
- Install the CMA brackets on the outer rails. See Figure 3.
- Install the outer rails (right outer rail) onto the rack post.
Align the right outer rail to the rack post at the desired height shown in Figure 4 below. The same goes for the left outer rail. Swing Open the front latch hook. Aim the front rackmount pins at the rack post openings and pull forward to sit on the post. Close the front latch hook. Open the rear latch. Aim the rear rack mount pins at the rack post openings and pull forward to sit on the post. Close the rear latch hook. Tighten the front bracket with the screw (M5x13L) Tighten the rear bracket with the screw (5Mx12L) Repeat the same steps above for the left outer rail.
Insert the chassis into the rack
-
Extend the outer rail extension until it is fully extended and locked into position as shown in Figure 5 ①.
-
Both left and right outer rails should be fully extended and locked.
Ensure the ball bearing retainers are locked at the front of the outer rail extensions as shown in Figure 5 ②. -
Aim the rear end of inner rail to the outer rail extension and insert the chassis horizontally to the outer rail extension as shown in Figure 5 ③. Make sure the inner rails slide into the grooves correctly.
-
When the chassis is locked, push the release blue tab on both sides of the rails and continue sliding the chassis into the rack as shown in Figure 5 ④&⑤.
-
Tighten chassis to the rack by thumb screws as shown in Figure 5⑥.
-
When transporting or moving the empty chassis in rack, please install the shipping screws.
Enclosure layout
To find the drive slot number, refer to the label on the top cover of each row
as shown in Figure 6.

Connecting to a host with an external SAS HBA (Lenovo 440-16e SAS HBA)
With a single Lenovo 440-16e (or 440-8e) SAS HBA, it can support up to two
D4390 enclosures chaining together as shown in Figure 8 below.
Connecting to a host with an external RAID adapter
(Lenovo 940-8e RAID adapter)
With a single Lenovo 940-8e RAID adapter, it can support up to one D4390
enclosure as in Figure 9 below. Be sure to change the RAID adapter profile to
ID 32.
