EMC® VNX5300™ Hardware Information Guide
describes the 2U, 25 (2.5-inch) DAE power supply/cooling module LEDs.
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 SAS x4 ports
◆
One management (RJ-12) connector
6-Gb/s SAS x4 ports
The DAE LCC supports two 6-Gb/s SAS x4 ports (labeled 6Gb 0 x4) on the rear of
each SP (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 HD 26-circuit cable
(plug) with a pull tab.
Note:
Each SAS cable is keyed with an
in
and
out
connection to prevent incorrect cabling.
shows an example of the port connector (socket) and cable connector (plug)
with pull tab.
