This section provides instructions on installing the DS4700 Express. The installation process includes: v “Removing the CRUs” v “Installing the DS4700 Express into a rack on the support rails” on page 46 v “Replacing the components” on page 48 Removing the CRUs This section describes how to remove the CRUs to minimize the weight of the DS4700 Express before you install it in the rack.
Page 73: Removing A Controller
The DS4700 Express comes with a rack-mounting hardware kit for installing it in a rack. It is easier to lift the DS4700 Express and install it in a rack cabinet if you remove all the CRUs first. You will need an antistatic wrist strap and a cart or level surface (to hold the CRUs).

Loop diameter of 76 mm (3 in.) and bend radius of 38 mm (1.5 in.) for fibre-optic cables are IBM DS4000 recommended minimums. Loops or bends smaller than this recommendation may cause damage to your fiber optic cables. It is best practice to use loop diameters and bend radii that are greater than these recommended minimums.
Page 90: Installing Sfp Modules
In addition, do not use long-wave SFPs or GBICs in any of the fibre channel ports in the DS4700 Express controllers. (Long-wave SFPs and GBICs are not supported for use in the DS4700 Express or any of the attached DS4000 storage expansion enclosures.) v The SFP module housing has an integral guide key that is designed to prevent you from inserting the SFP module improperly.

1. Do not connect a combination of more than six EXP810 storage expansion enclosures to the two ports of a dual-ported drive channel. Failure to observe this limitation might result in loss of data availability. In the DS4700 Express Storage Subsystem environment, no more than six EXP810 storage expansion enclosures can be connected to the two ports of a dual-ported drive channel because of the internal drive slots in the DS4700 Express Storage Subsystem.
