Troubleshooting guide

xxii
Do not touch the SFP-T during operation and just after operation stops.
• During operation (when a link is established), the temperature of the SFP-T can rise to
65?C. Do not touch the device while it is operating or just after it stops. Doing so could
result in burns.
• When you remove the SFP-T, use the following procedure. Failure to do so could result in
burns.
1. To remove the device when the Switch is turned on, execute the
inactivate command,
and then wait five minutes before removing the device.
2. To remove the device after turning off the Switch, turn off the Switch, wait five minutes,
and then remove the device.
• The following label is attached to the SFP-T.
Lithium battery
• The Switch has a lithium battery for the real-time clock. Incorrect handling of the lithium
battery could cause the battery to heat up, explode, or catch fire, resulting in injury or a
fire. Do not remove the battery from the Switch, disassemble it, heat it to 100C or higher,
incinerate it, or immerse it in water.
Cleaning
• Remove dust on and around the Switch regularly. In addition to causing the Switch to stop,
accumulated dust could result in a fire or electric shock.
