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.

(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.

Removing an interface card
CAUTION:
•
Before you remove an interface card, r
emove 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.
