For information on Aruba optical transceivers and cable assemblies supported on your Aruba 6400 Switch,
see the latest version of the ArubaOS-Switch and ArubaOS-CX Transceiver Guide at https://

You can install or remove SFP and QSFP form-factor transceivers without having to power off the switch.
Installing a transceiver
1. Wear an ESD wrist strap with snug skin contact and reliable grounding. (SeeAttaching an ESD wrist
2. Unpack the module. Hold it carefully by its sides. Avoid touching the plated contacts.
3. Slide the transceiver into a slot until it clicks into place.
Removing a transceiver
1. Wear an ESD wrist strap with snug skin contact and reliable grounding. (See Attaching an ESD wrist
strap.)
2. Disconnect the network cable from the transceiver before removing it from the module. Depending on
when you purchased your transceiver, it may have either of three different release mechanisms: a plastic
tab on the bottom, a wire bail, or a plastic collar.
• To remove the transceivers that have the plastic tab or plastic collar, push in the plastic tab or collar
toward the switch until you see the transceiver release from the switch (you can see it move outward
slightly), and then pull it from the slot.
• To remove the transceivers that have the wire bail, lower the bail until it is approximately horizontal,
then using the bail, pull the transceiver from the slot.
3. Place the transceiver in an ESD-protectected container.
4. If you are leaving the transceiver slot empty, install a dust cover.
Installing a fan tray in an empty fan tray slot
Fan trays are installed in the slots on the rear of the chassis.
CAUTION: For proper cooling and ventilation, a powered-up 6400 Series chassis must have all
fan trays installed and all fans in each fan tray running. Do not remove a fan tray from a
powered up switch without having a replacement fan tray available. When replacing a fan tray in
an operating switch, install the replacement fan tray within two minutes of removing the
original fan tray.
CAUTION: Replace only one fan tray at a time. Removing more than one fan tray at a time
compromises system cooling, risks damage to the hardware, and can cause the switch to shut
down abruptly.
CAUTION: Handle your Aruba 6400 switch fan trays with care. Rough or careless handling can
damage these components and result in unplanned down time.
IMPORTANT: The Aruba 6405 Switch operates with two fan trays, and the Aruba 6410 switch
operates with four fan trays. For proper air flow, ensure that all fan tray slots are occupied with
fully functioning fan trays.
