Allow at least 24 in. (61 cm) both in front of and behind thedevice.• If you are mounting the device in a rack with other equipment, or if you are placing iton the desktop near other equipment, ensure that the exhaust from other equipmentdoes not blow into the intake vents of the chassis.Table 20 on page 40 provides information on the clearance requirements for maintainingthe optimum airflow and the distances for facilitating easy maintenance of the device.Table 20: Clearance Requirements for the Services GatewayRequirement for ClearanceRecommended ClearanceLocationSpace for service personnel to remove andinstall hardware componentsNOTE: More space is required for installing andremoving Mini-PIMs.2.5 in.
