Installing/removing fan trays
CAUTION:
The switch has multiple fan tray slots. For adequate heat dissipation, follow these guidelines:
•
The S9825-64D switch with the LS-S9825-64D product code came with the six fan tray slots
empty. Before powering on the switch, make sure it fully configured with fan trays and the fan
trays are the same model.
•
The S9825-64D switch with the LS-9825-64D-H1 product code came with the eight fan tray slots
empty. When you install ZR or ZR+ modules in the two lower rows of ports on the switch, make
sure all fan tray slots on the switch have fan trays installed. In other situations, you can install six
fan trays in slots FAN3 to FAN8.
•
Make sure each slot has a module or filler panel installed when the switch is operating.
•
If multiple fan trays fail on the operating switch, do not remove the fan trays at the same time.
Replace the fan trays one after another and finish replacing a fan tray within 3 minutes.
Select fan trays compatible with the switch. For the optional fan trays and their specifications, see
H3C S9825 & S9855 Switch Series Hardware Information and Specifications

Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, 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.
To install a fan tray:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the fan tray and verify that the fan tray model is correct.
3.
Orient the fan tray with the connector facing downwards. Pressing the red part of the handle
with one hand and supporting the fan tray bottom with the other, slide the fan tray along the
guide rails into the slot until the fan tray is fully seated in the slot and has a firm contact with the
backplane.
