Checking Racks

Checking Racks

Properly installed racks of the storage device help ensure the stable and long-term running of the storage device. Check rack conditions periodically to reduce device failure possibilities.

Impact on the System

The storage device imposes demanding requirements on rack conditions. An improperly installed rack impairs the proper running of the storage device.

Tools and Materials

Ensure that the tools and materials for checking rack conditions are available. The required tools include binding straps, an electroprobe, and a multimeter.

Reference Standard

Table 9-2 lists the items and standards for checking rack conditions.
Table 9-2  Rack condition check items and standards

Layout of power cables

Power cables are laid out orderly and arranged in a similar manner to power cables on other racks.

Layout of service cables

Service cables are laid out orderly and arranged in a similar manner to service cables on other racks.

Cable labeling

Labels are clearly marked and securely attached.

Empty slot

Empty slots are covered with filler panels for proper heat dissipation and a neat appearance.

Power cable plug

One end of each power cable is fully plugged into an external power socket and the other end into a storage device socket.

Signal cable plug

Signal cables are fully plugged into appropriate device ports.

Ground cable

One end of each ground cable is secured by a ground clip and the other end is fastened to a rack ground terminal.

Power cable

Two groups of power cables are available for redundancy.

Host port connection

  • For Ethernet host ports, one end of each network cable is fully plugged into a storage device host port and the other end into an application server port or a switch port.
  • For Fibre Channel or FCoE host ports, one end of each optical fiber is fully plugged into a storage device host port and the other end into an application server port or a switch port.

Management network port connection

One end of each management network cable is fully plugged into a storage device management network port and the other end is connected to the network where the maintenance terminal resides.

Procedure

  • Verify that power cables (with strong electrical current) and service cables (with weak electrical current) lay on different sides of a rack.
  • Verify that power cables and service cables are laid out orderly and arranged in a similar manner to cables on other racks.
  • Verify that labels are clearly marked and securely attached.
  • Verify that vacant slots are covered with filler panels.
  • Verify that one end of each power cable is fully plugged into an external power socket and the other end into a storage device socket.
  • Verify that signal cables are fully plugged into appropriate device ports.
  • Verify that one end of each ground cable is secured by a ground clip and the other end is fastened to a rack ground terminal.
  • Verify that two groups of power cables are available for redundancy.
  • Verify that one end of each network cable or optical fiber is fully plugged into a storage device host port and the other end into an application server port or a switch port.
  • Verify that one end of each management network cable is fully plugged into a storage device management network port and the other end is connected to the network where the maintenance terminal resides.
