Caution: Airflow around the switch must be unrestricted. To prevent the switch from overheating, there must be the
following minimum clearances:
– Top and bottom: 2.0 in. (50.8 mm)
– Sides: 1.0 in. (25.4 mm)
– Front: 2.0 in. (50.8 mm)
Contact your Cisco Technical Assistance Centre (TAC) if tighter spacings are required.
Caution: The device is intended for vertical installations only.
Caution: Ensure the device is not installed in an environment that exceeds the approved ambient temperature
range.
Caution: The device is designed to mount on a DIN rail that conforms to Standard EN50022.
North American Hazardous Location Approval
The following information applies when operating this equipment in hazardous locations:
EMC Environmental Conditions for Products Installed in the European Union
This section applies to products to be installed in the European Union.
The equipment is intended to operate under the following environmental conditions with respect to EMC:
A separate defined location under the user’s control.
Earthing and bonding shall meet the requirements of ETS 300 253 or CCITT K27.
AC-power distribution shall be one of the following types, where applicable: TN-S and TN-C as defined in IEC

In addition, if equipment is operated in a domestic environment, interference could occur.
English: Products marked "Class I, Div 2, GP A, B, C, D" are suitable for use in Class I Division 2 Groups A,
B, C, D, Hazardous Locations and nonhazardous locations only. Each product is supplied with
markings on the rating nameplate indicating the hazardous location temperature code. When
combining products within a system, the most adverse temperature code (lowest "T" number)
may be used to help determine the overall temperature code of the system. Combinations of
equipment in your system are subject to investigation by the local Authority Having Jurisdiction at
the time of installation.
Français: Informations sur l'utilisation de cet équipement en environnements dangereux:
Les produits marqués "Class I, Div 2, GP A, B, C, D" ne conviennent qu'à une utilisation en
environnements de Classe I Division 2 Groupes A, B, C, D dangereux et non dangereux. Chaque
produit est livré avec des marquages sur sa plaque d'identification qui indiquent le code de
température pour les environnements dangereux. Lorsque plusieurs produits sont combinés dans
un système, le code de température le plus défavorable (code de température le plus faible) peut
être utilisé pour déterminer le code de température global du système. Les combinaisons
d'équipements dans le système sont sujettes à inspection par les autorités locales qualifiées au
moment de l'installation.
