● Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
● Use conductive field service tools.
● Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized technician install the part.
For more information about static electricity or assistance with product installation, contact customer support. For additional
information, see www.dell.com/support.
Dealing with hardware faults
Ensure that you have obtained a replacement module of the same type before removing any faulty module.
CAUTION:
● If the enclosure system is powered up and you remove any module, replace it immediately. If the enclosure
system operates for too long with a module removed, the enclosures can overheat, causing power failure and
potential data loss. Such use may invalidate the warranty.
● Observe applicable/conventional ESD precautions when handling modules and components, as described in
Replacing controller modules in a dual-controller module enclosure on page 61. Avoid contact with midplane
components, module connectors, leads, pins, and exposed circuitry.
Firmware updates
After installing the hardware and powering on the storage system components for the first time, verify that the controller
modules, expansion modules, and disk drives are using the current firmware release. Periodically, ensure that the firmware
versions used in the enclosure modules are compatible.
Configuring partner firmware update
In a dual-controller system in which partner firmware update (PFU) is enabled, when you update firmware on one controller, the
system automatically updates the partner controller. Disable PFU only if requested by a service technician. Use the PowerVault
Manager or CLI to change the PFU setting.
NOTE:
● See the topic about updating firmware in the Dell EMC PowerVault ME4 Series Storage System Administrator’s Guide
before performing a firmware update.
● The PowerVault Manager and CLI provide an option for enabling or disabling PFU for the partner controller as described
in the Dell EMC PowerVault ME4 Series Storage System Administrator’s Guide. To enable or disable the setting via
the CLI, use the set advanced-settings command, and set the partner-firmware-upgrade parameter. See the Dell EMC
PowerVault ME4 Series Storage System CLI Guide for more information about command parameter syntax.
Continuous operation during replacement
Your hardware or software enclosure management application determines the capability for replacing a failed disk without the
loss of access to any file system on the enclosure. Enclosure access and use during this period is uninterrupted. If an enclosure
is equipped with redundant PCMs or PSU, sufficient power is provided to the system while the faulty module is replaced.
NOTE:
ME4 Series Storage System enclosures support hot-plug replacement of redundant controller modules, power
supplies, and expansion modules. Hot-add replacement of expansion enclosures is also supported.
