76 VNX5700 Hardware Information Guide
Disk-array enclosure
The power supply/cooling modules are located to the left and right of the LCCs. The units
integrate independent power supply and dual-blower cooling assemblies into a single
module.
Each power supply is an auto-ranging, power-factor-corrected, multi-output, offline
converter with its own line cord. Each supply supports a fully configured DAE and shares
load currents with the other supply. The drives and LCCs have individual soft-start
switches that protect the disk drives and LCCs if they are installed while the disk enclosure
is powered up. The enclosure cooling system includes two dual-blower modules.
The 2U, 25 (2.5-inch) DAE LCC input/output ports and connectors
The 2U, 25 (2.5-inch) DAE LCC supports the following I/O ports on the rear:
◆ Two 6-Gb/s PCI Gen 2 SAS ports
◆ One management (RJ-12) connector to the SPS (not used)
6-Gb/s SAS x4 ports
The DAE LCC supports two (one input and one output) 6-Gb/s SAS x4 ports (labeled 6Gb
SAS x4) on the rear of each LCC (A and B). This port provides an interface for SAS and
NL-SAS drives on the DAE. This 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.
Note: Each SAS cable is keyed with an
in
and
out
connection to prevent incorrect cabling.
Figure 65 shows an example of the port connector (socket) and cable connector (plug)
with pull tab.
