EMC VNX Series Operating instructions

TECHNICAL NOTES
This document describes the few exceptions in which DC-powered VNX series systems
differ from their AC counterparts. Topics include:
◆Power considerations......................................................................................... 2
◆Cabling DC power and powering the system up and down .................................. 8
◆Installing a DC-AC inverter ................................................................................ 13
In general, you configure, operate, and maintain DC-powered systems as you would
the more common AC systems except:
◆DC power supplies in the VNX5100, VNX5300, and VNX5500 disk processor
enclosures (DPE) and DAE6S disk array enclosures include power on/off switches
or buttons.
◆DC storage systems do not include standby power supplies (SPS).
◆DC storage systems that support file I/O include 1U DC-AC inverters for the control
stations.
• In VNX5100, VNX5300, and VNX5500 systems, the inverters occupy the
physical space reserved for an AC SPS.
• VNX5200, VNX5400, and VNX5600 systems install the inverters directly above
the control stations.

Power considerations
Power considerations
IMPORTANT
Systems with DC power are intended for use in environments with redundant and
highly available power sources (for example, "Central Office" grade power within the
telecommunications industry), and DC power provided by the site must meet this
requirement. The sudden loss of all incoming DC power to a storage system may
cause unexpected abnormal behavior of the storage system and loss of write-cache
data.
Power distribution must support the number of outlets required for the device (two
per enclosure) and the device power rating. Tables 1 through 4 list the power
specifications for EMC®VNX™ series disk processor, data mover, and disk-array
enclosures.

Cabling DC power and powering the system up and down
Cabling DC power and powering the system up and down
After installing the storage-system hardware, cable DC power and power up the
system components.
Note: VNX DPEs and DAEs start immediately when connected to active DC input; you
do not need to press or toggle the power switches.
Connect each power supply to a DC power source. See Figure 3 for systems that
support only block IO; Figure 4 on page 9 and Figure 5 on page 10 show typical
unified or file IO configurations.
For high availability, be sure to connect the A and B power cords in each enclosure to
different power source feed circuits.
Note: Grounding screws on the power supplies provide additional grounding
sources, if necessary.

Cabling DC power and powering the system up and down
DC-Powered VNX™ Series Enclosures Installation and Operation Guide 11
Powering down a DC-powered VNX series system
With the following exceptions , you power down VNX series storage systems with DC
power as you would an AC system (documented on the EMC online support website
at:
http://mydocs.emc.com/VNX/)
After you stop all I/O activity to the storage system and, if necessary, unmount the file
systems:
VNX5100,
VNX5300, and
VNX5500
◆To turn off disk processor enclosure power, push the power button on each power
supply and hold the button in for two seconds. Refer to Figure 6.
Figure 6 DC power buttons —DPE
Allow the power supply to complete its shutdown sequence before removing the
power source. An orderly shutdown that flushes all cache can take up to several
seconds before the host sends a STOP to the power supply. We recommend that
you wait two minutes before removing a power supply from the DPE chassis.

◆If necessary, turn off power to other components as follows:
• Toggle the DAE6S power switches to the off position.
Figure 7 DC power switches —DAE6S
• On the data mover enclosure, remove the front bezel. Push the power button
on each power supply and hold the button in for two seconds.
Figure 8 DC power buttons —data mover
Wait at least 2 minutes before removing a power supply from the data mover
chassis.
• Remove the power cords from DAE5S enclosures.
• Remove the DC input power cords from control station inverters.

Installing a DC-AC inverter
DC-Powered VNX™ Series Enclosures Installation and Operation Guide 13
Installing a DC-AC inverter
DC storage systems that support file I/O include 1U DC-AC inverters for the control
stations. Each control station connects to an inverter, which is in turn connected to
the DC power source. Figure 4 on page 9 shows a typical VNX example; VNX II systems
typically install the inverters above the control stations, as shown in Figure 5 on
page 10.
To install a DC-AC inverter assembly, follow these steps:
1. From the front of the cabinet, insert the alignment pin on one mounting rail
assembly into the middle hole of the selected 1U space on a rear channel.
2. Extend the rail to the front cabinet channel. Align the holes of the front rail flange
to the inside of the channel, ensure the rail is level, and then install two M5 x 16
mm Phillips securing screws in the top and bottom holes.
Leave the screws slightly loose to allow for adjustment when you install the tray.
Do not insert a screw in the middle hole yet.
3. At the back of the cabinet, insert and tighten two M5 x 16 mm securing screws in
the holes above and below the alignment pin, as shown above. Repeat steps 1
through 3 for the other rail assembly.

4. Slide the tray onto the mounting rails in the cabinet, until the flanges of the tray
are flush with the cabinet channels.

5. At the front of the cabinet, tighten the four securing screws (two on each side) that
hold the mounting rails to the channels, then secure the tray to the channels with
a single screw on each side.

8. If necessary, use one Phillips M5 x 16-mm screw to secure a latch bracket to each
front channel. The brackets include small alignment bumps to correctly orient
them to the channel.
9. Press the bezel onto the latch brackets until it snaps into place.
