EMC® VNX5300™ Hardware Information Guide
Power supply The power supply/cooling module integrates independent power supply and blower
cooling assemblies into a single module.
Each power supply is an auto-ranging power-factor-corrected, multi-output, off-line
converter with its own line cord. The drives and LCC have individual soft-start
switches that protect the disk drives and LCC if you install them while the disk
enclosure is powered up. A disk or blower with power-related faults will not affect
the operation of any other device.
Each power/cooling module has three status LEDs (Figure 58 on page 62 and
Figure 63 on page 66).
Cooling modules The enclosure cooling system consists of dual-blower modules in each power
supply/cooling module.
EMI shielding EMI compliance requires a properly installed electromagnetic interference (EMI)
shield in front of the DAE disk drives. When installed in cabinets that include a front
door, the DAE includes a simple EMI shield. Other installations require a front bezel
that has a locking latch and integra ed EMI shield. You must remove the bezel/shield
to remove and install disk drive modules.
The 3U, 15 (3.5-inch)
DAE front view
On the front, viewing from left to right, the Block and File VNX5300 platform 3U, 15
(3.5-inch) disk drive DAE carrier includes the following hardware components:
◆ 3.5-inch 6-Gb/s SAS, 6-Gb/s NL-SAS, or Flash disk drives (hot-swappable)
16
◆ Status LEDs
Figure 56 on page 59 shows the location of these components.
Note: In a Block and File VNX5300 platform, when using the 3U, 15 (3.5-inch) disk drive
carrier, the maximum amount of disk drives is 120 (including DPE and expansion DAEs).
16. You can add or remove a disk drive while the DAE is powered up, but you should exercise
special care when removing modules while they are in use. Drive modules are extremely
sensitive electronic components.
