Installing and removing a fan tray
CAUTION:
•
You can power on the switch only when the switch has two fan trays of the same model installed.
•
Do not leave any slots empty when the switch is operating. Install a module or filler panel in the
slots.
•
If both fan trays fail while the switch is operating, replace them within 2 minutes.
•
If one fan tray fails while the switch is operating, perform either of the following tasks:
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and
make sure the failed fan tray is in position before the replacement.
If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
•
If you power cycle the switch after a fan tray fails, the switch will fail to start up.
The switch comes with empty fan tray slots. It supports the LSWM1FANSCE, LSWM1FANSCBE,
FAN-40F-1-A, and FAN-40B-1-A fan trays.
•
The LSWM1FANSCE fan tray provides power supply-side intake and port-side exhaust airflows.
The fan tray handle is blue.
•
The LSWM1FANSCBE fan tray provides port-side intake and power supply-side exhaust
airflows. The fan tray handle is red.
•
The FAN-40F-1-A fan tray provides power supply-side intake and port-side exhaust airflows.
The fan tray handle is blue.
•
The FAN-40B-1-A fan tray provides port-side intake and power supply-side exhaust airflows.
The fan tray handle is red.
Select the fan trays for the switch based on the ventilation requirements at the installation site. For
the fan trays available for the switch, see removable fan trays in
Hardware Information and
Specifications
.
The installation and removable procedures are the same for the LSWM1FANSCE,
LSWM1FANSCBE, FAN-40F-1-A, and FAN-40B-1-A fan trays. The following procedure installs and
removes an LSWM1FANSCBE fan tray.
Installing a fan tray
1.
Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably
grounded.
2.
Unpack the fan tray and verify that the fan tray model is as required.
3.
Orient the fan tray with the TOP mark facing up.
4.
Align the fan tray with the fan tray slot. Holding the fan tray handles, slide the fan tray into the
slot along the guide rails. Make sure the fan tray is fully seated in the slot and has a firm contact
with the backplane.
To prevent damage to the fan tray or the connectors in the chassis, insert the fan tray gently. If
you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it
again.
