Review 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.
• Locate the enclosure low enough for the rack to remain stable.
• Ensure that you 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.

• Each system enclosure to be installed requires 2U of rack space.
• Each assembled enclosure weighs more than 18 kg. Provide sufficient space at the front of the rack for two persons to carry the enclosure safely.
• Install all enclosures that constitute one system in contiguous positions in a rack. Place the control enclosure in the middle of the rack.
• Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP control enclosures systems can support up to 10 expansion enclosures on one chain. Lenovo Storage V5030 and Lenovo Storage V5030F systems can support two chains and each chain can support up to 10 expansion enclosures.
• 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 chain to an existing system

If you are adding an expansion enclosure chain to an existing Lenovo Storage V5030 or Lenovo Storage V5030F system, follow these guidelines.

• You do not need to power off the system. You can add an expansion enclosure while the system is operational.
• Add the first expansion enclosure directly below the control enclosure.
• Add the second expansion enclosure directly above the control enclosure.
• Add the third expansion enclosure directly below the first.
• Add the fourth expansion directly above the second, and so on.
