CAUTION:
The 5800-48G-PoE+ (2 slots), 5800-48G-PoE+ TAA (2 slots), 5800-24G-SFP (1 slot), and
5800-24G-SFP TAA (1 slot) switches, and all 5820X switches except the 5820AF-24XG have only one
fan tray slot. To ensure good ventilation, follow these guidelines:
• Do not operate the switch without a fan tray.
• If the fan tray has problems durin
correctly.
• Do not operate the system with only one fan tray for more than 24 hours.
• Do not operate the system without any fan tray for more than 2 minutes.
• Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.
Failure to comply with these operating requirements might void the warranty.
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 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 correctly 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 Figure 24, Figure 25, or Figure 26).
4. Fasten the captive screw on the fan tray with a Phillips screwdriver until the fan tray is securely
seated in the chassis (see callout 2 in Figure 24, Figure 25, or Figure 26).
If the captive screw cannot be tightly fastened, examine the installation of the fan tray.
