Safety guidelines

Safe handling

CAUTION: Use this equipment in a manner specified by the manufacturer: failure to do this may cancel the protection
provided by the equipment.
• Permanently unplug the enclosure before you move it or if you think that it has become damaged in any way.
• A safe lifting height is 20U.
• Always remove the Power and Cooling Modules (PCMs) to minimize weight before you move the enclosure.
• Do not lift the enclosures by the handles on the PCMs—they are not designed to take the weight.
CAUTION: Do not try to lift the enclosure by yourself:
• Fully configured 2U12 enclosures can weigh up to 32 kg (71 lb)
• Fully configured 2U24 enclosures can weigh up to 30 kg (66 lb)
• Fully configured 5U84 enclosures can weigh up to 135 kg (298 lb). An unpopulated enclosure weighs 46 kg (101 lb).
Use appropriate lifting methods. Before lifting the enclosure:
Unplug all cables and label them for reconnection.

Remove DDICs from drawers and verify the drawers are closed and firmly locked. See also

Use a minimum of three people to lift the enclosure using the lifting straps provided.

Avoid lifting the enclosure using the handles on any of the CRUs because they are not designed to take the

weight.
Do not lift the enclosure higher than 20U. Use mechanical assistance to lift above this height.

• Observe the lifting hazard label affixed to the storage enclosure.

Operation

IMPORTANT: Operation of the enclosure with any CRU modules missing will disrupt the airflow, and the enclosure will
not receive sufficient cooling. It is essential that all slots hold modules before the enclosure system is used. Empty drive
slots (bays) in 2U enclosures must hold dummy drive carrier modules. See also
• Observe the module bay caution label affixed to the module being replaced.
• Replace a defective PCM with a fully operational PCM within 24 hours. Do not remove a defective PCM unless you
have a replacement model of the correct type ready for insertion.
• Before removal/replacement of a PCM or PSU, disconnect supply power from the module to be replaced. Please refer
to "Replacing a power cooling module" (page
• Observe the hazardous voltage warning label affixed to power cooling modules.
