Identify the hardware components
The following graphics identify the hardware components and port locations for the control enclosure and expansion enclosure on Storwize® V3700 systems.
Control enclosure components
Figure 1 shows the rear view of a control enclosure and identifies the location of the power supply units and node canisters.
Figure 1. Rear view of a Storwize V3700 control
enclosure

Note: Figure 1 and Figure 2 show an enclosure that is equipped with alternating current
(AC) power supplies. Some enclosure enclosure models have direct current (DC) power supplies instead
(see Reviewing your packing slip for the model numbers).
For more information about DC power supply units, see Direct current power supply units.
Note: Figure 1 shows the
node canisters in their initial configuration, with no host interface adapter options
installed.
Data ports
Figure 2 shows the rear view of a Storwize V3700 control enclosure and identifies the location of the ports.

Control enclosure support rails
The left and right control enclosure support rails (Figure 3) are designed specifically for
installation of a control enclosure.

Expansion enclosure components
Figure 4 shows the location of
the power supply units and expansion canisters.

expansion enclosure

Note: Figure 4 shows an enclosure that is equipped with alternating
current (AC) power supplies. Some enclosure models have direct current (DC) power supplies instead
(see Reviewing your packing slip for the model numbers).
For more information about DC power supply units, see Direct current power supply units.
Figure 5 shows the LEDs and SAS port locations from the rear view of
an expansion canister.

expansion canister

Each canister has two SAS ports that are numbered 1 on the left and 2 on the right. Port 1 is always used. Port 2 is used only if this is not the last enclosure in the chain.
Expansion enclosure support rails
The left and right expansion enclosure support rails (Figure 6) are designed specifically for
installation of an expansion enclosure.
