Installing and removing an interface card

	CAUTION: ·     Before you install or remove an interface card, wear an ESD wrist strap and make sure the strap makes good skin contact and is reliably grounded. ·     To avoid device damage, do not use excessive force when you install or remove an interface card. ·     The LSWM124XG2QFC interface card is hot swappable. However, do not install or remove it during the startup of the switch.

 

Installing an interface card

Before you install an interface card, remove the filler panel (if any) from the target slot. Keep the removed filler panel secure for future use.

To install an interface card:

1.     Unpack the interface card.

Figure 2 LSWM124XG2QFC interface card

(1) Ejector lever	(2) Latch

 

2.     Press the latch on the interface card to release the ejector lever.

3.     As shown by callout 1 in Figure 3, insert the interface card slowly into the slot along the guide rails.

4.     Rotate inward the ejector lever as shown by callout 2 in Figure 3 until the latch locks the ejector lever in place.

Figure 3 Installing an LSWM124XG2QFC interface card

 

Removing an interface card

	CAUTION: ·     Before you remove an interface card, remove the cable from it to avoid cable damage. ·     After removing an interface card, if no new interface card is to be installed, install the filler panel as soon as possible to prevent dust and ensure good ventilation in the device.

 

To remove an interface card:

1.     Prepare an anti-static bag.

2.     Press the latch to release the ejector lever

3.     Rotate outward the ejector lever as shown by callout 1 in Figure 4.

4.     Pull out the interface card slowly out of the interface card slot, as shown by callout 2 in Figure 4.

5.     Place the removed interface card in the anti-static bag.

Installing and removing SFP, SFP+, and QSFP+ transceiver modules and SFP+ and QSFP+ cables

For information about installing and removing SFP/SFP+ transceiver modules and SFP+ cables, see H3C Transceiver Modules and Network Cables Installation Guide at www.h3c.com.

For information about installing and removing QSFP+ transceiver modules and QSFP+ cables, see H3C Transceiver Modules and Network Cables Installation Guide at www.h3c.com.

Verifying the installation

After the installation is complete, identify whether the interface card is operating correctly.

If the interface card fails to operate correctly, perform the following steps:

1.     Reinstall it following the installation procedures described in this document.

2.     If the problem persists, contact H3C Support.
