Removing an Ethernet Module from the Chassis

To remove an Ethernet module from the chassis, perform these steps:

Step 1 Disconnect any network interface cables attached to the Ethernet module.

Step 2 Attach an ESD grounding strap to your wrist and to a proper ground.

Step 3 Verify that the captive installation screws on all of the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.

Note If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on the installed modules expand and push the modules toward the open slot, which reduces the opening size and makes it difficult to reinstall the module.

Step 4 Loosen the two captive installation screws on the Ethernet module.

Step 5 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of substeps:

Horizontal slots

a. Place your thumbs on the left and right ejector levers located on the left and right sides of the module faceplate, and simultaneously rotate the levers outward to unseat the Ethernet module from the chassis backplane connector.

b. Grasp the front edge of the Ethernet module and slide the module part of the way out of the slot. Place your other hand under the Ethernet module to support the weight of the module. Do not touch the module circuitry.

c. Place the removed Ethernet module on a properly grounded antistatic mat or antistatic foam.

Vertical slots

a. Place your thumbs on the ejector levers located at the top and bottom of the Ethernet module, and simultaneously rotate the levers outward to unseat the Ethernet module from the chassis backplane connector.

b. Grasp the front edge of the Ethernet module and slide the module part of the way out of the slot. Place your other hand under the Ethernet module to support the weight of the module. Do not touch the module circuitry.

c. Place the removed Ethernet module on a properly grounded antistatic mat or antistatic foam.

Installing an Ethernet Module in the Chassis

Caution To prevent ESD damage, handle modules by the carrier edges only and wear grounding wrist straps.

---

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

To install a module in the chassis, perform these steps:

Step 1 Verify that an ESD grounding strap is attached to your wrist and to proper ground.

Step 2 Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step assures that the EMI gaskets on all of the installed modules are fully compressed in order to maximize the opening space for the Ethernet module.

Note If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on the installed modules expand and push the modules toward the open slot, which reduces the opening size and makes it difficult to reinstall the module.

Step 3 Fully open both ejector levers on the Ethernet module. (See Figure 19.)

Step 4 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of substeps:

Horizontal slots

a. Position the Ethernet module in the slot. (See Figure 19.) Make sure that you align the edges of the module carrier with the slot guides on each side of the slot.

b. Carefully slide the Ethernet module into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have engaged and closed to approximately 45 degrees with respect to the Ethernet module faceplate. (See Figure 20.)

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small (0.040 inch [1 mm]) gap between the module’s EMI gasket and the module above it. (See Figure 20.)

Caution Do not press down too hard on the levers because they can bend and be damaged.

---

d. While gently pressing down, simultaneously close the left and right ejector levers to fully seat the Ethernet module in the chassis backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 21.)

Note Failure to fully seat the module in the chassis backplane connector can result in error messages.

e. Tighten the two captive installation screws on the Ethernet module.

Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.

f. Verify that the Ethernet module STATUS LED is lit. Check the STATUS LED periodically. If the STATUS LED changes from orange to green, the module has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the module has not successfully completed the boot process and may have encountered an error.

Figure 21 Ejector Lever Closure in a Horizontal Slot Chassis

Vertical slots

a. Position the Ethernet module in the slot. (See Figure 22.) Make sure that you align the edges of the module carrier with the slot guides on the top and bottom of the chassis slot.

b. Carefully slide the Ethernet module into the slot until the EMI gasket along the right edge of the module faceplate makes contact with the module in the slot adjacent to it and both ejector levers have closed to approximately 45 degrees with respect to the Ethernet module faceplate. (See Figure 23.)

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and exert a slight pressure to the left, deflecting the module approximately 0.040 inches (1 mm) to create a small gap between the module’s EMI gasket and the module adjacent to it. (See Figure 23.)

Caution Do not exert too much pressure on the ejector levers because they can bend and be damaged.

---

d. While gently pressing on the ejector levers, simultaneously close them to fully seat the Ethernet module in the chassis backplane connector. The ejector levers are fully closed when they are flush with the Ethernet module faceplate. (See Figure 24.)

e. Tighten the two captive installation screws on the Ethernet module.

Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.

f. Verify that the Ethernet module STATUS LED is lit. Check the STATUS LED periodically. If the STATUS LED changes from orange to green, the module has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the module has not successfully completed the boot process and may have encountered an error.
