Every S10500 switch provides an ESD wrist strap. To minimize ESD damage to electronic components, wear the ESD wrist strap and make sure it is reliably grounded when installing modules.

To use an ESD wrist strap:

1. Make sure the switch is reliably grounded. For how to ground your switch, see "Grounding the switch."

2. Put on the wrist strap.

3. Tighten the wrist strap to make sure it makes good skin contact.

Make sure the resistance reading between your body and the ground is between 1 and 10 megohms.

4. As shown in Figure 3-1, insert the ESD wrist strap into the ESD socket (with an ESD sign) on the switch chassis, or attach it to the grounding screw of the chassis with an alligator clip.

Figure 3-1 Attaching an ESD wrist strap (S10506)

Installing a card

IMPORTANT:

· Before installing a card in the chassis, make sure the connectors on the card are not broken or blocked to avoid damaging the backplane.

· To ensure good ventilation, install a blank filler panel in an empty slot.

· Before you install a card that has a protection box, remove the protection box from the card as follows:

a. Loosen the captive screws that secure the card to the protection box.

b. Pull the ejector levers of the card outwards.

c. Pull the card out of the protection box.

The cards for the switch include MPUs, service modules, and switching fabric modules. They are hot swappable.

· To install a card in a horizontal slot, make sure its PCB components face up.

· To install a card in a vertical slot, make sure its PCB components face left.

The installation procedure is similar for the cards. The following procedure installs a card in a horizontal slot.

To install a card:

1. Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2. Remove the blank filler panel (if any) from the slot. Keep the blank filler panel for future use.

3. Fully open the two ejector levers on the card.

For a base card, rotate the ejector levers down to the horizontal position.

Figure 3-2 Rotating down the ejector levers on a base card

4. Hold the card by the front panel with one hand and support the card bottom with the other. Slide the card steadily into the slot along the guide rails until you cannot push the card further. Do not touch the components on the card.

5. Fully close the ejector levers so that the card comes in close contact with the backplane.

For a base card, rotate the ejector levers inward and then upward to the vertically closed position.

Figure 3-3 Rotating up the ejector levers on a base card

6. Fasten the captive screws on the card.

7. When the switch is powered on, verify the running status of the card.

You can verify the running status of a card by referring to the card status LED (SLOT) on the MPU of the switch. If the RUN LED flashes, the card in the slot operates correctly. For more information about card status LED (SLOT), see "Appendix C LEDs."

Figure 3-4 Installing a card

Installing a subcard

IMPORTANT:

To ensure good ventilation, install a blank filler panel in an empty subslot.

This section describes how to install a subcard in a base card. Subcards are hot swappable.

To install a subcard:

1. Wear an ESD wrist strap, and make sure it has good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2. Make sure a base card is installed in the switch.

3. Unpack the subcard.

4. If the target slot has a blank filler panel, remove the blank filler panel from the slot.

Keep the removed blank filler panel for future use.

5. Install the subcard in the base card:

a. Simultaneously rotate outward the two ejector levers on the subcard.

b. Gently push the subcard (with bottom up) into the slot along the guide rails until the ejector levers come in contact with the base card panel.

c. Push the subcard by its front panel until you cannot push the subcard further.

d. Rotate inward the ejector levers so that the subcard panel is flush with the base card panel.

6. Fasten the captive screws on the subcard.

(Optional) Installing transceiver modules and network cables

WARNING!

Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the switch is operating.

Installing transceiver modules

CAUTION:

To avoid transceiver module or port damage, read this guide carefully before installing a transceiver module.

CAUTION:

· Be careful not to touch the golden plating on a transceiver module during the installation process.

· Before installing a transceiver module, remove the optical fibers, if any, from it.

· Make sure the transceiver module is aligned correctly with the target port before pushing it into the port.

· Do not remove the dust plugs from a transceiver module until you are ready to connect optical fibers to it.

Installing an XFP/SFP+/SFP/SFP28/QSFP+/QSFP28 module

Two types of QSFP+ transceiver modules are available. One type uses a metal pull latch and the other type uses a plastic pull latch. The installation procedure is the same for the two types of QSFP+ transceiver modules.

The installation procedure is similar for the XFP, SFP+, SFP, SFP28, QSFP+, and QSFP28 transceiver modules. The following procedure installs an SFP+ transceiver module.

To install an SFP+ transceiver module:

1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2. Remove the dust plug from the target fiber port.

3. Unpack the SFP+ module. It comes with the bail latch catching the knob on the top of the transceiver module.

4. Grasp the transceiver module between your thumb and index finger. Align it with the fiber port and push it gently into the port until it snaps into place.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

5. Connect optical fibers to the transceiver module. For the connection procedure, see "Connecting your switch to the network through optical fibers."

Figure 3-20 Installing an SFP+ module

Installing a CFP module

1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2. Remove the dust plug from the target fiber port.

3. Unpack the CFP module.

4. Correctly orient the transceiver module and align it with the fiber port. Push it gently into the port until you feel it snaps into place. See Figure 3-21.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

5. Fasten the captive screws on the transceiver module to secure the module in place.

6. Connect optical fibers to the transceiver module. For the connection procedure, see "Connecting your switch to the network through optical fibers."

Figure 3-21 Installing a CFP module

Connecting network cables

CAUTION:

When you connect a network cable, follow these restrictions and guidelines:

· Make sure the two modular ends of a network cable are compatible with the ports into which they will be inserted.

· Do not touch the golden plating on the two modular ends of a network cable.

· To avoid network cable damage and signal loss, do not strain or tangle a network cable.

· Before inserting a modular end of a network cable into a port, make sure the module aligns with the port correctly.

· The bend radius of a DAC cable and AOC cable must be a minimum of 15 and 20 times the cable diameter, respectively.

To connect ports over a short distance, use network cables as follows:

· SFP+ DAC cable—Connects two SFP+ ports over a short distance.

· QSFP+ DAC cable or QSFP+ AOC cable—Connects two QSFP+ ports over a short distance.

· QSFP+ to SFP+ DAC cable—Connects one QSFP+ port to four SFP+ ports over a short distance.

The network cables are hot swappable. The connection procedure is similar for these cables. The following procedure connects an SFP+ DAC cable.

To connect an SFP+ DAC cable:

1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap."

2. Remove the dust plug from the target fiber port.

3. Unpack the cable.

4. As shown in Figure 3-22, align the module end of the cable with the fiber port and push it gently into the port until you feel it snaps into place.

Transceiver modules and fiber ports have disorientation rejection structures. If you cannot insert a transceiver module easily into a port, remove and reorient the transceiver module.
