Installing and replacing a fan tray
The installation and removal procedures are the same for the
LSVM1S9810FAN and LSVM2S9810FAN fan trays.
Installing a fan tray
IMPORTANT:
Before you install a fan tray,
• Determine the required number of fan trays based on the
number of installed switching fabric modules. If one switching
fabric module is installed, one fan tray is required. If two
switching fabric modules are installed, two fan trays are
required.
• Make sure the airflow direction of the fan tray meets the
ventilation requirement at the installation site.
• Make sure a switching fabric module has been installed in the
slot below the target fan tray slot.
• To install two fan trays, make sure the models of the two fan
trays are the same.
To install a fan tray:
1. Wear an ESD wrist strap, and make sure it makes good skin
contact and is reliably grounded.
2. Use both hands to hold the fan tray with the "TOP" sign on the top
surface. Gently push the fan tray into the slot along the guide rails
until the fan tray is completely seated in the slot. See callout 1
in
Figure 3 and Figure 4 .
