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 a minimum of two people to lift the 5U84 enclosure from the shipping box and install it in the rack.
Before lifting the enclosure:
• 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.
Safe operation
Operation of the enclosure with modules missing disrupts the airflow and prevents the enclosure from receiving sufficient cooling.
NOTE:
For a 2U enclosure, all IOM and PCM slots must be populated. In addition, empty drive slots (bays) in 2U
enclosures must hold blank drive carrier modules. For a 5U enclosure, all controller module, IOM, FCM, and PSU slots
must be populated.
• Follow the instructions in 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. See the
Dell EMC PowerVault ME4 Series Storage System Owner’s Manual.
.
• Follow the instructions in the hazardous voltage warning label affixed to power cooling modules.
CAUTION:
5U84 enclosures only
• To prevent a rack from tipping over, drawer interlocks stop users from opening both drawers simultaneously. Do not
attempt to force open a drawer when the other drawer in the enclosure is already open. In a rack containing more
than one 5U84 enclosure, do not open more than one drawer per rack at a time.
• Observe the hot surface label that is affixed to the drawer. Operating temperatures inside enclosure drawers can
reach 60°C (140°F) . Take care when opening drawers and removing DDICs.
• Due to product acoustics, ear protection should be worn during prolonged exposure to the product in operation.
• Observe the drawer caution label. Do not use open drawers to support any other objects or equipment.
Electrical safety
•
The 2U enclosure must be operated from a power supply input voltage range of 100–240 VAC, 50/60Hz.
•
The 5U enclosure must be operated from a power supply input voltage range of 200–240 VAC, 50/60Hz.
•
Provide a power source with electrical overload protection to meet the requirements in the technical specification.
•
The power cord must have a safe electrical grounding connection. Check the grounding connection of the enclosure before you
switch on the power supply.
NOTE:
The enclosure must be grounded before applying power.
• The plug on the power supply cord is used as the main disconnect device. Ensure that the socket outlets are located
near the equipment and are accessible.
• 2U enclosures are intended to operate with two PCMs.
• 5U84 enclosures are intended to operate with two PSUs.
• Follow the instructions that are shown on the power-supply disconnection caution label that is affixed to power
cooling modules.
CAUTION:
Do not remove the covers from the enclosure or any of the modules as there is a danger of electric shock
inside.
