Disk-array enclosures
LCC input/output ports, connectors, and LEDs
The 3U, 120 (2.5-inch) DAE LCC supports the following I/O ports on the rear:
◆ Four 6-Gb/s PCI Gen 2 mini-SAS ports
◆ One management (RJ-12) connector (not used in the VNX5400 platform)
◆ One USB connector
6-Gb/s mini-SAS x4 ports — The LCC supports four (two input with a double circle
and
two output with a double diamond ) 6-Gb/s mini-SAS x4 ports (labeled 6 Gb SAS x4 1
or 0) on the rear of each LCC (A and B) as shown in Figure 74. This port provides an
interface for SAS and NL-SAS drives in the DAE. The port is a 26-circuit SAS small
form-factor 8088 (SFF-8088) specification (socket or receptacle) using an SFF-8088
specification mini-SAS 26-circuit cable (plug) with a pull tab.
Mini-SAS connector LED — A blue/green link/activity LED next to the mini-SAS port
indicates the DAE connection status. Blue indicates that the port is established at a
maximum bus speed of 6-Gb/s. Green indicates that a wide port width other than 4x is
established or one or more lanes is not operating at the maximum bus speed.

Note: As described in the previous paragraphs, the first connection from the DAE comes
from the four, 6-Gb/s mini-SAS ports. This connection uses a a 26-pin mini-SAS small
form-factor 8088 (SFF-8088) specification connector (plug) with a pull (release) tab on one
end of the cable, while the DPE side uses a 36-pin mini-SAS HD small form-factor 8644
(SFF-8644) specification connector (plug) with a pull (release) tab (see Figure 13 on
page 29) on the other end of the cable.
For more information about the mini-SAS HD to mini-SAS cable, refer to the DPE “Base
module” on page 26. A complete description of the mini-SAS HD connector and cable end
is provided. Additionally, a video describing how to properly connect mini-SAS HD cables
and mini-SAS cables from a DPE to a DAE, respectively in a VNX product is available online
at: https://edutube.emc.com/, in the Search box, type in Mini-SAS HD Cable Connectivity.
The video will start immediately.
