Figure 4: Install an AC Power Supply in a S5860-20SQ Switch image.png Maintain SFP+/SFP28/QSFP+ Transceivers Purpose For optimum performance, verify the condition of the SFP+/SFP28/QSFP+ Transceivers. Action Keep fiber patch cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection. To clean the transceivers, use an appropriate fiber-cleaning device, such as ATC-NE-E1. Follow the directions for the cleaning kit you use. After you clean an optical transceiver, make sure that the connector tip of the fiber patch cable is clean. Use only an approved alcohol-free fiber patch cable cleaning kit, such as the ATC-NE-R2 Fiber Cleaner. Follow the directions for the cleaning kit you use. Remove an SFP+/SFP28/QSFP+ Transceiver Before you remove a transceiver from a device, ensure that you have taken the necessary precautions for safe handling of lasers. Ensure that you have the following parts and tools available: An antistatic bag or an antistatic mat Rubber safety caps to cover the transceiver and fiber patch cable connector A dust cover to cover the port or a replacement transceiver The transceivers for FS Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace the transceivers without powering off the device or disrupting the device functions. Note: After you remove a transceiver, or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands. We recommend that you use only optical transceivers and optical connectors purchased from FS Networks with your FS Networks device. To remove an SFP+/SFP28/QSFP+ transceiver: 1. Place an antistatic bag or antistatic mat on a flat, stable surface to receive the transceiver. Have a rubber safety cap ready for the transceiver and the cable. 2. Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch. 3. Label the cable connected to the transceiver so that you can later reconnect it to the correct transceiver. 4. Disconnect the cable from the transceiver. Immediately cover the transceiver and the end of the cable with a rubber safety cap. Caution: Do not leave a fiber-optic transceiver uncovered, except when inserting or removing a cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light. 5. If there is a cable management system, arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it does not support its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape. Caution: Do not bend the fiber patch cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose. 6. To remove an SFP, SFP+, SFP28 transceiver (see Figure 5): a. Using your fingers, pull open the ejector lever on the transceiver to unlock the transceiver. Caution: Before removing the transceiver, make sure that you open the ejector lever completely until you hear it click. This precaution prevents damage to the transceiver. b. Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port. Caution: To prevent ESD damage to the transceiver, do not touch the connector pins at the end of the transceiver. c. Using your fingers, grasp the body of the transceiver and pull it straight out of the port. To remove a QSFP+ transceiver (see Figure 6): Pull the ejector tab straight back. The locking pins on the transceiver automatically release the transceiver. Figure 5: Remove an SFP, SFP+, SFP28 Transceiver image.png Figure 6: Remove a QSFP+ Transceiver output (4).jpg 7. Place the transceiver on the antistatic mat or in the antistatic bag. 8. Place the dust cover over the empty port, or install the replacement transceiver. Install an SFP+/SFP28/QSFP+ Transceiver Before you install a transceiver in a device, ensure that you have taken the necessary precautions for safe handling of lasers. Ensure that you have a rubber safety cap available to cover the transceiver. The transceivers for FS Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace the transceivers without powering off the device or disrupting the device functions. Note: After you insert a transceiver or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands. We recommend that you use only optical transceivers and optical connectors purchased from FS Networks with your FS Networks device. Caution: The FS Networks Technical Assistance Center (FS TAC) provides complete support for FS-supplied optical modules and cables. However, FS TAC does not provide support for third-party optical modules and cables that are not qualified or supplied by FS Networks. If you face a problem running a FS device that uses third-party optical modules or cables, FS TAC may help you diagnose host-related issues if the observed issue is not, in the opinion of FS TAC, related to the use of the third-party optical modules or cables. If you encounter a network failure, your FS TAC engineer will likely request that you check the third-party optical module or cable and, if required, replace it with an equivalent FS-qualified component. Use of third-party optical modules with high-power consumption (for example, coherent ZR or ZR+) can potentially cause thermal damage to or reduce the lifespan of the host equipment. Any damage to the host equipment due to the use of third-party optical modules or cables is the users’ responsibility. FS Networks will accept no liability for any damage caused due to such use. To install an SFP+/SFP28/QSFP+ transceiver (see Figure 7): 1. Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch. 2. Verify that a rubber safety cap covers the transceiver. 3. Position the transceiver in front of the port on the device so that the connector faces the port. Figure 7: Install an SFP+/SFP28/QSFP+ Transceiver image.png 4. Slide the transceiver into the port until the locking pins lock in place. If there is resistance, remove the transceiver and flip it so that the connector faces the other direction. 5. Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver. Laser Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber patch cables. Fiber-optic transceivers and fiber patch cable connected to a transceiver emit laser light that can damage your eyes. Caution: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light. 6. If there is a cable management system, arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it does not support its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape. Caution: Do not let fiber patch cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point. Avoid bending fiber patch cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose. Maintaining Fiber Patch Cables Purpose For optimum performance, verify the condition of the network cables. Action On a regular basis: Secure excess cable in tidy loops that do not obstruct access to the device. Do not allow fastened loops of cable to dangle from the connector, because this stresses the cable at the fastening point. Putting fasteners on the loops helps maintain their shape. Keep the cable connections clean and free of dust and other particles, which can cause drops in the received power level. Always inspect cables and clean them if necessary before connecting an interface. Label both ends of the cables to identify them. The following guidelines apply specifically to fiber patch cables that connect to optical transceivers that are installed in FS Networks devices: When you unplug a fiber patch cable, always cover the cable connector with the rubber safety cap. Anchor fiber patch cables to avoid stress on the connectors. Be sure to secure fiber patch cables so that they do not support their own weight as they hang to the floor. Never let fiber patch cable hang free from the connector. Avoid bending fiber patch cable beyond its bend radius. An arc smaller than a few inches can damage the cable and cause problems that are difficult to diagnose. Frequent plugging and unplugging of fiber patch cable into and out of optical instruments can cause damage to the instruments that are expensive to repair. Instead, attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easy and inexpensive to replace. Disconnect a Fiber Patch Cable Before you disconnect a fiber patch cable from an optical transceiver, ensure that you have taken the necessary precautions for safe handling of lasers. Ensure that you have the following parts and tools available: A rubber safety cap to cover the transceiver A rubber safety cap to cover the fiber patch cable connector FS Networks devices have optical transceivers to which you can connect fiber patch cables. To disconnect a fiber patch cable from an optical transceiver installed in the device: Laser Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber patch cables. Fiber-optic transceivers and fiber patch cables connected to transceivers emit laser light that can damage your eyes. 1. Carefully unplug the fiber patch cable connector from the transceiver. Two types of latches on fiber optic connectors: a. LC/PC connector, opened by pressing the buckle, as shown in Figure 8. b. MPO connector, opening automatically when the buckle is pulled, as shown in Figure 9. Figure 8: LC/PC Connector image.png Figure 9: MPO Connector image.png 2.
