grounding strip in the equipment room as long as possible.

Installing/removing a fan tray

Only the S5500-28SC-HI and S5500-52SC-HI switches support hot-swappable fan trays.
CAUTION:
Each of the S5500-28SC-HI and S5500-52SC-HI switches has only one fan tray slot for the
hot-swappable fan tray. To ensure good ventilation, follow these guidelines:
Do not operate the switch without a fan tray.
•
• If the fan tray has problems during operation, replace it within 2 minutes while the switch is operating.

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 well grounded.
2. Unpack the fan tray and verify that the fan tray model is correct.
3. Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other, and
slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has a firm
contact with the backplane (see callout 1 in
