Reviewing enclosure location guidelines
|
|
Before installing the enclosures, you must be familiar with these enclosure location
guidelines.
Installing a control enclosure only
If you are installing a control enclosure only, follow these guidelines.
Position the enclosure in the rack so that you can easily view it and access it for
servicing. Ensure that you locate the enclosure low enough for the rack to remain
stable and provide a way for two or more people to install and remove the
enclosure.
Installing a control enclosure and one or more expansion
enclosures
If you are installing a control enclosure plus one or more expansion enclosures,
follow these guidelines.
v Each Storwize V3700 enclosure to be installed requires 2U of rack space.
v Each assembled enclosure weighs more than 18kg. There must be sufficient
space at the front of the rack for two persons to carry the enclosure safely.
v Install all enclosures that constitute one system in contiguous positions in a rack,
with control enclosure at the top.
v Each control enclosure supports connection to up to four expansion enclosures.
If this system installation has less than four expansion enclosures, reserve space
directly below the system to allow future expansion.
v If a rack is to be only partially filled, install the enclosures low enough for the
rack to remain stable and enable easy access to the enclosures for servicing.
Adding an expansion enclosure to an existing system
If you are adding an expansion enclosure to an existing system, follow these
guidelines.
v You do not need to power off the system. You can add an expansion enclosure
while the system is operational.
v Add the first expansion enclosure directly below the control enclosure.
v Add the second expansion enclosure directly below the first, and so on.
