a. Not UL 60950 certified.
b. Temperature of the ambient air at a distance of 2 inches (5 cm) from the device
c. If you are using SFP modules without the “EEC” extension, an operating temperature of
+32 °F to +140 °F (0 °C to +60 °C) applies for your device. See “Accessories” on page 54.
d. Applies to device variants GRS....-8T8Z... with the extended temperature range:
e. If more than 4 SFP transceivers are used, the maximum operating temperature is reduced
by 2 K per additional SFP transceiver.
