Fan tray failure

CAUTION:
The HPE 5950 32QSFP28 switch has six fan tray slots. The HPE 5950 48SFP28 8QSFP28 switch
has five fan tray slots. The HPE 5950 4-slot switch has two fan tray slots. To replace failed fan trays
on an operating switch, follow these guidelines:
• If multiple fan trays fail on an operating HPE 5950 32QSFP28 or HPE 5950 48SFP28 8QSFP28
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.
• If a fan tray fails on an operating HPE 5950 4-slot switch, replace the fan tray immediately and
keep the failed fan tray in position before replacement. If two fan trays fail, finish replacing the fan
trays within 1 minute.
