Note:

1. Make sure that the bottom edge of the chassis rail is aligned with the bottom U that
you want the chassis to rest on.

2. If you misalign the chassis rail, press the locking hooks release or squeeze the locking hooks
on the chassis rail, slide the posts out of the holes, and try again.

3. Make sure that the chassis rail posts protrude through the holes
on the front EIA flange.

Note: For detailed instructions, see the Lenovo Flex System Enterprise Chassis
Types 7893, 8721, and 8724 Installation and Service Guide.

2.5

Pull the chassis rail forward and insert the posts on the front of the chassis rail into the
holes on the front EIA flange until it snaps into place. Repeat steps 2.4 and

2.5 for the right chassis rail.

Verify the shipment contents:

1.2

Become familiar with the chassis components. The following modules are standard:
One System Chassis Management Module (CMM), two or more power supplies, six or more fan modules, and two fan logic modules. The chassis might
also include one or more compute nodes, storage nodes, and a management node. The features or modules that you receive might differ from the contents
shown in Figures 1 and 2, depending on what you ordered (see Figures 1 and 2).

To decrease the weight and make the chassis easier to install in a rack, remove
components from the chassis. Make a note of each component location so that
the component can be reinstalled in the same location. Press on the colored
latch and pull on the handles to remove the components. You can also remove
the shelves from the chassis to reduce the weight further.

4. Install an M5 combi-head screw in each end of the rail.
Use the lower threaded hole on the front and the upper
threaded hole on the rear.

Align the rack template with the holes in the EIA flange (internal to rack).
For EIA flanges with square holes, install M5 cage nuts from the accessory
kit in the holes that are indicated on the template. If the EIA flanges have
round holes, install the M5 clip nuts from the accessory kit instead of the
M5 cage nuts.

Note: Install cage nuts or clip nuts on the front and back EIA flanges.

• Make sure that there is sufficient room in front of the front EIA flange to
provide minimum bezel clearance of 50 mm (1.97 inches).

Next Steps

Connect an Ethernet cable from a client computer to the active Chassis
Management Module (CMM) by a direct connection. If two CMMs are
installed, you only have to configure the primary CMM. The

will be lit ( ) on the primary CMM.

To connect to the CMM for the first time, you might have to change the
Internet Protocol properties on the client computer. Make sure that the
the client computer subnet is the same as the CMM subnet
(the default CMM subnet is 255.255.255.0). The CMM IP address must
also be in the same local domain as the client computer IP address.

Open a web browser on the client computer, and direct it to the CMM IP
address. You must use a secure connection ( ). https://192.168.70.100

4.5

The first time you log in to the CMM, the initial setup wizard opens.
Perform the initial configuration of the CMM.

Network access tag

The network access tag lists the following initial
connection information for the CMM:

• MAC address

• Default host name

• IPv6 Link Local Address (LLA)

• Default IPv4 static IP address (192.168.70.100)

• Default user name (USERID)

• Default password (PASSW0RD, where
the number zero, not the letter O, is used)

Restart the CMM from the CMM user interface. As the CMM is restarting,
connect a cable from the Ethernet port on the CMM to your network.

The network access tag is attached to the front of the CMM.

Initial setup is now complete. You are ready to begin using the
Lenovo Flex System Enterprise Chassis.

4.4

Enter the CMM user name and password to start the remote session.

• The user ID and password are case sensitive. The same user ID and
password are used for all methods of connecting to the CMM.

• The default CMM user name is USERID, and the default password is
PASSW0RD (note the number zero, not the letter O, in PASSW0RD).
You will be required to change the default password when you log
in for the first time.

Note: The manufacturing default static IPv4 IP address is

192.168.70.100, and the default IPv4 subnet address is 255.255.255.0.

5.5

Log in to the user interface of each of the switches in the chassis and
configure them.

If you plan to transport the rack to another location, you
must install the support brackets that come with the chassis.

1. Align the right support bracket with the four slots on the rear
of the chassis (outside of the chassis wall).

2. Slide the support bracket forward until it locks into place in the slots.

3. Secure the support bracket to the rack with three M5 combi-head

screws (black).

4. Repeat steps 1 through 3 for the left support bracket.

5. Fit the lower support bracket to the chassis; then, slide it forward

against the rack rails and secure the bracket with four M5 combi-head
screws (black).

After you complete the initial configuration, you can access the Flex
System Manager user interface to complete the setup and begin
managing the chassis.

On a client computer that is connected to your network,
point your browser to , where IP_address
is the IP address that you entered during the initial configuration
(in step 5.3).

Note: When you reinstall the compute nodes, storage nodes, and

the Flex System Manager management node, be sure to install
from the bottom up (the first node in node bay 1, the second node
in node bay 2, and so on).

If any of the LEDs are not lit, complete the following steps:

1. Remove power from the chassis.

2. Reseat all components in the chassis.

3. Supply power to the chassis. If the problem remains,
contact Support.

Set the IP address for each of the components in the chassis. This
includes the IP address of the IMM or FSP in each of the compute nodes
and the IP address of each of the switches in the chassis. From the
CMM user interface, select Chassis Management > Component
IP Configuration. Then, select a device to change its IP address.

Notes:

• You must restart each device to show the new IP address.

• Due to the design of the Flex System Chassis, it is important to have all
management network traffic on a separate subnet than the data traffic.
This means all CMMs, IMMs, FSPs, and switch management interfaces
should be on a different subnet/VLAN than the data production traffic of
the other chassis components (such as node operating systems).
