QSFP transceiver
Before installing an SFP+ or QSFP transceiver, be aware of the following information:
The housing on the transceiver includes an integral guide key that is designed to prevent you
from inserting the transceiver incorrectly.
Use minimal pressure when you insert the transceiver into the port. Forcing the transceiver
into the port can cause damage to the transceiver or the switch port.
You can insert or remove the transceiver while the chassis is powered on.
You must first insert the transceiver into the port before connecting the cables.
You must remove the cable from the transceiver before you remove the transceiver from the
switch.
Do not route the cable along a folding cable-management arm.
When you attach the cable to a device on slide rails, leave enough slack in the cable so that it
does not bend to a radius of less than 38 mm (1.5 in.) when the device is extended, or become
pinched when the device is retracted.
Route the cable away from places where it can be snagged by other devices in the rack.
Do not overtighten the cable straps or bend the cables to a radius of less than 38 mm (1.5 in.).
Do not put excess weight on the cable at the connection point. Make sure the cable is well
supported.
