Guidelines for Using Fiber Optic Cables

•Do not route the cable along a folding cable management arm.

•For devices on slide rails, leave enough slack in the cables so they do not bend to a diameter of less than 76 mm (3"), or a radius less than

38 mm (1.5"), when extended or become pinched when retracted.

•Route the cable away from places where it can be damaged by other devices in the rack cabinet.

•Do not use plastic cable ties in place of the provided cable straps.

•Do not over-tighten the cable straps or bend the cables to a diameter of less than 76 mm (3") or a radius less than 38 mm (1.5").

•Do not place excess weight on the cable at the connection point. Ensure that the cable is well supported.

Guidelines for Using SFP Modules

The storage array requires SFP modules. SFP modules convert electrical signals to optical signals that are required for FC transmission to and from RAID controller modules. After installing the SFP modules, fiber optic cables are used to connect the storage array to other FC devices. Before installing SFP modules and fiber optic cables, read the following information:

•Use only Dell supported SFPs with the PowerVault MD3600f series storage arrays. Other generic SFPs are not supported and may not work with the storage arrays.

•The SFP module housing has an integral guide key that is designed to prevent you from inserting the SFP module incorrectly.

•Use minimal pressure when inserting an SFP module into a FC port. Forcing the SFP module into a port may damage the SFP module or the port.

•You can install or remove the SFP module while the port is powered on.

•You must install the SFP module into a port before you connect the fiber optic cable.

•You must remove the fiber optic cable from the SFP module before you remove the SFP module from the port.

CAUTION: When handling static-sensitive devices, take precautions to avoid damaging the product from static electricity.
