Before you begin

CAUTION:
This assembly contains mechanical moving parts. Use care when you service this assembly. (C025)

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 RPC card to local remote switch card cable

Procedure

  1. To locate this FRU, take one of the following actions and then return here and continue to replace the FRU:
    • If this FRU has a FRU identify indicator, use the FRU identify indicator, which is listed in MAP1240 Locating FRUs by using identify indicators. If not, use the location code.
      Note: There might be cases where the FRU failure or fencing conditions prevent the FRU LED indicator from being lit even if the FRU has power.
    • Use the location code, which is listed in MAP1245 Finding FRUs by using location codes.
    • If there is no FRU identify indicator or location code, you were sent here by an isolation MAP or symbolic FRU procedure. Use the information in that procedure and the figures in this procedure to locate the proper part to exchange.
  2. Most, but not all, FRUs have identify indicators. Use the flashing amber or solid blue FRU identify indicators to ensure that you are working on the correct enclosure or FRU.
  3. 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.

    See Table 1, Figure 2, Figure 3, and Figure 4. Squeeze the tab to release the cable.
    Note: The J1 and J2 cables can be unplugged to provide better access to J3.
