Electrical safety

  • The enclosure must only be operated from a power supply input voltage range of 200–240 VAC, 50/60Hz.
  • Provide a suitable power source with electrical overload protection to meet the requirements in the technical specification.
  • The power cord must have a safe electrical earth connection. Check the connection to earth of the enclosure before you switch on the power supply.
  • The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must maintain a voltage with not more than ± 5 percent fluctuation. The customer facilities must also provide suitable surge protection.
Important:
  • 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 easily accessible.
  • Disk Enclosures are intended to operate with two PSUs and four system fans accessed from the rear panel. Two controller channel fan modules accessed from the top of the enclosure provide additional cooling.
  • Observe the power-supply disconnection caution label affixed to PSU modules.
CAUTION:
Do not remove covers from the PSU or any other CRU module. There is a danger of electric shock inside. Return the plug-in module to your supplier for repair.
Important: The RJ-45 socket on IOMs is not currently supported and must not be connected to a telecommunications network.
  • IBM COS Medium and Large Disk Enclosures are suitable for connection to intra-building or non-exposed wiring or cabling only.
  • IBM COS Medium and Large Disk Enclosures are suitable for installation in locations where the NEC (National Electrical Code) applies. These enclosures are not suitable for Outside Plant (OSP) installations.
