Dell PowerVault ME4 Series Storage System Deployment Guide

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 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 prevent you from opening both drawers simultaneously. Do not attempt to force open a drawer when one 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.
