Installing/removing a fan tray
CAUTION:
The A5800-48G-PoE+ (2 slots), A5800-48G-PoE+ TAA (2 slots), A5800-24G-SFP (1 slot), and
A5800-24G-SFP TAA (1 slot) switches, and all A5820X switches except the A5820AF-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 during operation, replace it within 2 minutes while the switch is operating.
The A5800AF-48G and A5820AF-24XG switches require two same-direction air flow fan trays to
function properly.
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 may void the warranty.
Installing a fan tray
To install a fan tray:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Unpack the fan tray and check 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 good
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 Philips screwdriver until the fan tray is securely
attached in the chassis (see callout 2 in Figure 24, Figure 25, or Figure 26).
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.
If the captive screw cannot be tightly attached, check the installation of the fan tray.
