Description FRU part number Comments
Secondary expansion module 01LJ124 (for use
with enclosure
FRU P/N 01LJ112)
01LJ860 (for use
with enclosure
FRU P/N 01LJ607
The expansion enclosure supports two-
secondary expansion modules.
Note: The secondary expansion
modules are Tier 2 CRUs. You can
replace them or request that they be
replaced by IBM Service. For example, if
the enclosure is FRU P/N 01LJ112 and
it is powered on, you can contact your
service representative to replace the
secondary expansion module.
CAUTION: Use caution when
you are removing or replacing a
secondary expansion module
from an enclosure with FRU part
number 01LJ112. Avoid contact
with the connectors on the main
board.
Fan module 01LJ126 The expansion enclosure contains four
fan modules.
Expansion canister 01LJ128
Cable management arms (CMA) 01LJ130 The part contains the upper and lower
CMA.
Top cover 01LJ132
Fan interface board 01LJ134
Connecting the components
After installing the rails and enclosures in the rack, the Storwize V7000 2076-724 control enclosures are
connected to power, the network, and any optional expansion enclosures.
After all cabling connections are completed, the system components are powered on.
Connecting Ethernet cables to the node canisters
To provide system management connectivity for the system, connect Ethernet cables to Ethernet port 1
of both node canisters in the control enclosure.
Procedure
To install the Ethernet cables, complete the following steps.
1. Connect Ethernet port 1 of each node canister in the system to the IP network that will provide
connection to the system management interfaces, as shown in Figure 136 on page 124 and Figure 137
on page 124.
This port can also be used for iSCSI connectivity to the system by hosts on the network. Where more
than one control enclosure is present in the system, ensure port 1 of every node canister is connected
to the same network to provide access if the conîłguration node fails.
