Drive slots
A drive slot represents the location in an enclosure into which a drive can be inserted.
Each drive slot must contain either a drive or an empty carrier. The empty carriers do not have drive
indicators. The numbering scheme for the drive slots is indicated on the enclosure.
The following gure displays enclosures that have 24 drives, with 2.5-inch drive slots. The drive slots are
arranged in one row of vertically mounted drive assemblies.
IBM Elastic Storage System 3200 supports 12 and 24 drive congurations. All drives must be identical
in an IBM Elastic Storage System 3200 enclosure. In a 12 drive conguration, drives must be installed in
slots 1 - 6 and 13 - 18.

Power modules
Power modules are subcomponents of enclosures. A power module takes electrical power from the rack
Power Distribution Units (PDUs) and distributes the power to other components in the enclosure.
For redundancy, two power modules are installed in the enclosure.

SSR access port
The SSR access port is a designated USB mini serial port on the back panel of the canister that a service
personnel can use to initialize a system.
You can use the SSR access port to do the following tasks:
• Check the hardware and the USB mini cables (P/N 38L6355).
• Set the IP address of the management interface. For more information, see “Best practices for network
conguration (Customer reference task)” on page 61.
Each of the canisters in the IBM Elastic Storage System 3200 has an USB mini-B SSR access port, as
shown in the following gure.
