Exchange the Ethernet switch to management console Ethernet cable

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Note: All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.

Remove the Ethernet switch to CEC enclosure Ethernet cable

Procedure

  1. At the front of the rack, slide the management enclosure out to the service position and remove the top cover.
    Note: The management enclosure is below the two CEC enclosures.
    1. Fully loosen the left and right captive thumb screws.
    2. Slide the management out fully so the sliding rails lock into place.
    3. At the rear of the top cover, fully loosen the left and right captive thumb screws.
    4. Slide the cover back until it lifts off.

  2. The Ethernet connection between the Ethernet switch and management enclosure is inside the management enclosure.
  3. Locate the Ethernet cable.
    1. Two black Ethernet cables are between the upper (SW1) Ethernet switch and the management consoles. See Table 1, Figure 2, Figure 3, and Figure 4.

  4. Disconnect the cable at both ends.
  5. Remove the cable retention hardware as needed and remove the cable.

Install the Ethernet switch to management console Ethernet cable

Procedure

  1. Use the location code label on each end of the cable to ensure it is installed correctly.
  2. Route the cable and connect both ends.
  3. Reinstall the cable retention hardware.
  4. To verify the black and gray private networks, refer to MAP7001 Using the network topology tool.
  5. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
