Replacing an Optical Module

Replacing an Optical Module

This section describes the procedure for replacing an optical module.

Context

Before replacing an optical module, note the following:

  • Replacing an optical module interrupts services. Ensure that the optical module is faulty before replacing it.

  • Only external optical modules can be replaced. Internal optical modules can not be replaced.

  • You need to take antistatic measures before replacing an optical module.

  • When replacing an optical module, you do not need to swap boards.

  • When removing or inserting optical cables, be careful not to damage the optical cable connector.

  • When replacing an optical module, do not look directly into the fiber connector because the laser may harm your eyes.

An optical module is an electrostatic sensitive device. Therefore, you must take antistatic measures during the whole process of replacing an optical module to prevent the optical module from being damaged

Tool

Before replacing an optical module, you need the following tools:

  • ESD wrist strap or ESD gloves

  • ESD bag

Procedure

  1. Check the location of the optical module to be replaced.

    Before pulling out an optical module that is to be replaced, first check the location of the module, that is, the cabinet and chassis where the optical module resides, and label the optical module.

  2. Run the display interface interface-type interface-number command to view and record the type of the optical module to be replaced. The following displays the type in bold:

    <sysname> display interface gigabitethernet2/0/1
    GigabitEthernet2/0/1 current state : DOWN
    Line protocol current state : DOWN
    Description : Huawei, GigabitEthernet2/0/1 Interface, Route Port
    The Maximum Transmit Unit is 1500 bytes
    Internet Address is 172.16.1.1/24
    IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fcd4-7aad
    The Vendor PN is SCP6F86-GL-CWH
    Port BW: 1G, Transceiver max BW: 1G, Transceiver Mode: MultiMode
    WaveLength: 850nm, Transmission Distance: 300m
    Loopback:none, full-duplex mode, negotiation: disable, Pause Flowcontrol:Send and Receive Enable
    Statistics last cleared: never
        Last 30 seconds input rate: 0 bits/sec, 0 packets/sec
        Last 30 seconds output rate: 0 bits/sec, 0 packets/sec
        Input: 0 bytes, 0 packets
        Output: 0 bytes, 0 packets
        Input:
          Unicast: 0, Multicast: 0
          Broadcast: 0, Jumbo: 0
          CRC: 0, Symbol: 0
          Overrun: 0 , InRangeLength: 0
          LongPacket: 0 , Jabber: 0,  Alignment: 0
          Fragment: 0, Undersized Frame: 0
          RxPause: 0
      ---- More ----                  

  3. Record the location of the cables and check whether the labels on the cables are correct and clear. If the labels are not clear, re-make labels and re-label the cables.
  4. Wear the ESD gloves or wrist strap and connect the grounding terminal to the ESD jack on the rack.
  5. Pull out the optical module to be replaced.
    1. Remove the optical cables from the connector and cover the connector with a dust cap.
    2. Turn the optical module flap downward, as shown in Figure 3-36.
    3. Hold the flap to pull out the optical module carefully from the optical interface, as shown in Figure 3-36.
    4. Place the removed optical module in the ESD bag.

  6. Insert the new optical module into the optical interface.
    1. Take out the new optical module from the ESD bag and check whether there is any damage to it or component missing. Check whether the new optical module is of the same type as the optical module to be replaced.
    2. Insert the new optical module into the optical interface, as shown in Figure 3-37. The optical module is correctly inserted when you hear its reed click into place.

      If you cannot completely insert an optical module into an interface, do not force it. Instead, re-orient the module and insert it into the interface again.

    3. Remove the dust cap from the connector and insert the optical cables in the original sequence.
  7. Verify that the new optical module is working normally.

    Verify that the new optical module is working normally in the following ways:
    • Check the LINK indicator on the optical interface. If the indicator is green, the links connected to the interface are Up.
    • Run the display interface interface-type interface-number command on the console interface to view the type and running status of the new optical module. Check whether the type of the new optical module corresponds to that of the original optical module, as is displayed in bold as follows:
    <sysname> display interface gigabitethernet2/0/1
    GigabitEthernet2/0/1 current state : UP
    Line protocol current state : UP
    Description : Huawei, GigabitEthernet2/0/1 Interface, Route Port
    The Maximum Transmit Unit is 1500 bytes
    Internet Address is 172.16.1.1/24
    IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fcd4-7aad
    The Vendor PN is SCP6F86-GL-CWH

    WaveLength: 850nm, Transmission Distance: 300m
    Loopback:none, full-duplex mode, negotiation: disable, Pause Flowcontrol:Send an
    d Receive Enable
    Statistics last cleared: never
        Last 30 seconds input rate: 0 bits/sec, 0 packets/sec
        Last 30 seconds output rate: 0 bits/sec, 0 packets/sec
        Input: 0 bytes, 0 packets
        Output: 0 bytes, 0 packets
        Input:
          Unicast: 0, Multicast: 0
          Broadcast: 0, Jumbo: 0
          CRC: 0, Symbol: 0
          Overrun: 0 , InRangeLength: 0
          LongPacket: 0 , Jabber: 0,  Alignment: 0
          Fragment: 0, Undersized Frame: 0
          RxPause: 0
      ---- More ---- 
    
    • Check whether there is any new alarm or performance event.
    • Check whether the services are normal on the new optical module. If the services are normal, replacement is successful.

    If the new optical module is not working normally, contact a local Huawei office for technical support.

Follow-up Procedure

After replacing the optical module, collect all tools. If the replaced optical module is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
