Powering up the switch

Use this information to turn on the switch.

Before you begin

Before you turn on the switch, complete the steps in Verifying component installation.

Procedure

To power up the switch, complete the following steps.

  1. Power on the switch by turning the power switches of the power supplies or PEMs to the on (|) position or restoring power to the DC circuit, as required. The switch boots automatically.
  2. Listen for the fans. The fans begin operating as soon as the switch is powered on.
    CAUTION:
    Do not operate the switch without a functioning fan module except during the brief fan module replacement procedure. The IBM c-type SAN switches and devices can operate for only a few minutes without a functioning fan module before they begin to overheat.
  3. After the switch finishes booting up, verify that the LED indicators are showing the following status.
    • Fan module Status LED is green.
    • Power supplies Input OK LED is IN.
    • Power supplies Output Fail LED is Fault.
    • The System LED on the supervisor module is green, indicating that all chassis environmental monitors are reporting that the system is operational. If this LED is orange or red, one or more environmental monitors are reporting a problem.
    • The Status LED on the switching modules flashes orange once, remains orange during diagnostic boot tests, and then turns green when the module is operational (online). If the system software cannot start, this LED remains orange or turns red.
    Note: If you need technical support, contact IBM Support.
  4. Verify that the system software boots and that the switch initializes without error messages. If you cannot resolve an issue, contact your customer service representative.
  5. For future reference, complete the worksheets that are in Site planning and maintenance records.
    Note: A setup utility automatically starts the first time that you access the switch and guides you through the basic configuration. For instructions about how to configure the switch and check module connectivity, see Cisco NX-OS Fundamentals Configuration Guide or Cisco Fundamentals Configuration Guide for DCNM SAN..
