Handling Static-Sensitive Components
Static electricity can damage memory modules, system boards, and other
static-sensitive components. To prevent damaging the system, follow
these precautions:
• Move and store all components in the static-protective packaging.
• Place components on a grounded surface before removing them from their
static-protective packaging.
• Grounded surfaces include static-dissipating mats or grounded workstations.
• Always be properly grounded when touching a static-sensitive component.
To properly ground yourself, wear a wrist strap or boot strap made for this
purpose.
• Handle the component by its edges. Do not touch solder joints, pins, or
printed circuitry.
• Use conductive field service tools.
Host Cabling for Remote Replication
The Remote Replication premium feature provides online, real-time
replication of data between storage arrays over a remote distance. In the event
of a disaster or a catastrophic failure at one storage array, a second storage
array can be promoted to take over responsibility for computing services. The
Remote Replication premium feature requires a dedicated host port for
replicating data between storage arrays. After the Remote Replication
premium feature has been activated, one host I/O port on each RAID
controller module is solely dedicated to replicating operations.
