Maintaining MX-SPC3 Services Card
Maintaining MX-SPC3 Services Card
Purpose
For optimum router performance, verify the condition of the MX-SPC3 Services Card. To maintain MX-SPC3s cards, perform the following procedures regularly.
Action
On a regular basis:
Check the LEDs on the craft interface corresponding to the slot for each MX-SPC3. The green LED labeled
OK
lights steadily when a MX-SPC3 is functioning normally.Check the
OK/FAIL
LED on the MX-SPC3. If the MX-SPC3 detects a failure, the MX-SPC3 sends an alarm message to the Routing Engine.Issue the CLI show chassis fpc command to check the status of installed MX-SPC3s.
user@host> show chassis fpc
For more detailed output, add the detail option.
user@host> show chassis fpc detail
Issue the CLI show chassis fpc pic-status command.
user@host> show chassis fpc pic-status
For further description of the output from the command, see the CLI Explorer.
Replacing an MX-SPC3
Removing an MX-SPC3
The MX-SPC3 installs horizontally in the front of the MX240 & MX480 routers and vertically in the MX960 router. The MX-SPC3s are hot-insertable and hot-removable and the router continues to function when you remove an MX-SPC3.
A fully configured MX-SPC3 can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.
To remove an MX-SPC3:
- Have ready a replacement MX-SPC3 or a blank panel and an antistatic mat for the MX-SPC3. Also have ready rubber safety caps for transceivers.
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
- Label the cables connected to each port on the MX-SPC3 so that you can later reconnect the cables to the correct ports.
- Use one of the following methods to take the MX-SPC3 offline:
Press and hold the corresponding online button on the craft interface. The green
OK/FAIL
LED next to the button begins to blink. Hold the button down until the LED goes off.Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the CLI Explorer.
- Disconnect the cables from the MX-SPC3. If the MX-SPC3
uses fiber-optic cable, immediately cover each transceiver and the
end of each cable with a rubber safety cap.
Warning Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables 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 a cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
Caution Avoid bending a fiber-optic 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.
- Arrange the disconnected cables in the cable manager to prevent the cables from developing stress points.
- Simultaneously turn both the ejector handles counterclockwise to unseat the MX-SPC3.
- Grasp the handles, and slide the MX-SPC3 straight out of the card cage halfway.
- Place one hand around the front of the MX-SPC3 and the
other hand under it to support it. Slide the MX-SPC3 completely out
of the chassis, and place it on the antistatic mat or in the electrostatic
bag.
Caution The weight of the MX-SPC3 is concentrated in the back end. Be prepared to accept the full weight—up to 18.35 lb (8.3 kg)—as you slide the MX-SPC3 out of the chassis.
When the MX-SPC3 is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.
Do not stack MX-SPC3s on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
- If you are not reinstalling an MX-SPC3 into the emptied
line card slots within a short time, install a blank panel over each
slot to maintain proper airflow in the card cage.
Caution After removing an MX-SPC3 from the chassis:
Check the back panel connectors of the MX-SPC3 for damages. A damaged connector on the MX-SPC3 card can damage the chassis back plane.
Wait for at least 30 seconds before reinserting the MX-SPC3 into the same slot or inserting it into a different slot.
Installing an MX-SPC3
The MX-SPC3 installs horizontally in the front of the MX240 & MX480 routers and vertically in the MX960 router.
A fully configured MX-SPC3 can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.
Before installing an MX-SPC3 into the chassis:
Check the back panel connectors of the MX-SPC3 for damages. A damaged connector on the MX-SPC3 card can damage the chassis back plane.
Wait for at least 30 seconds, before reinserting the MX-SPC3 into the same slot or inserting it into a different slot.
To install an MX-SPC3:
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
- Place the MX-SPC3 on an antistatic mat.
- Locate the slot in the card cage in which you plan to install the MX-SPC3.
- Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it does not, cover the transceiver with a safety cap.
- Orient the MX-SPC3 so that the faceplate faces you.
- Lift the MX-SPC3 into place, and carefully align first
the bottom and then the top of the card with the guides inside the
card cage.
Caution When the MX-SPC3 is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.
- Slide the MX-SPC3 all the way into the card cage until you feel resistance.
- Grasp both ejector handles, and rotate them clockwise simultaneously until the MX-SPC3 is fully seated.
- If the MX-SPC3 uses fiber-optic cable, remove the rubber
safety cap from each transceiver and cable.
Warning Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.
- Insert the appropriate cables into the cable connector
ports on MX-SPC3. Secure the cables so that they are not supporting
their own weight. Place excess cable out of the way in a neatly coiled
loop, using the cable management system. Placing fasteners on a loop
helps to maintain its shape.
Caution Do not let fiber-optic cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.
Caution Avoid bending a fiber-optic 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.
- Use one of the following methods to bring the MX-SPC3
online:
Press and hold the corresponding MX-SPC3 online button on the craft interface until the green
OK/FAIL
LED next to the button lights steadily, in about 5 seconds.Issue the following CLI command:
user@host>request chassis fpc slot slot-number online
For more information about the command, see the CLI Explorer.
Caution After the
OK/FAIL
LED lights steadily, wait at least 30 seconds before removing the MX-SPC3 again, removing an MX-SPC3 from a different slot, or inserting an MX-SPC3 in a different slot.
