CAUTION: If any racks contain empty RU space, use the HP POD 20c filler panels to maintain the efficiency of the HP POD 20c thermal system. Filler panels are available from HP in 10-pack quantities (part number AQ682A) and 100-pack quantities (part number AS993A). For more information about racks and network cabling, see the HP Performance Optimized Datacenter Networking Guide. Aisle clearances Cold aisle clearance The maximum protrusion of any installed IT component directly impacts the available cold aisle clearance for removal and replacement of other IT components. Maximum component depth must follow the clear aisle distance calculations. The following figure shows how to calculate this distance. The maximum rack face-to-cold aisle wall distance is 39.5 inches. In the figure, X represents any protrusion into the cold aisle starting from the rack face of the installed IT component (for example, the bezel). Y represents cold aisle clearance. The cold aisle clearance dictates the maximum depth (D) of any installed IT component. To find the maximum cold aisle clearance, calculate 100.33 cm (39.5 in) - X = Y. IMPORTANT: As the value for X increases, the value for Y decreases, which also decreases the maximum depth allowed for an installed component. Illustrated parts catalog 10 Hot aisle clearance Hot aisle clearance is defined as the distance from the rear of the rack to the hot aisle wall. The reference distance of 2.54 cm (16 in) must be considered when selecting IT infrastructure that will populate into the hot aisle.

Regulatory requirements for EXIT signs Manufacturers of tritium EXIT signs are “specific licensees,” meaning they are licensed by the NRC or an Agreement State. The signs are considered “generally licensed devices,” because they are inherently safe enough to be handled or used by anyone with no radiation training or experience. Although purchasers – known as “general licensees” – do not need authorization from the NRC or a state regulatory agency to possess the signs, they are subject to certain regulatory requirements regarding handling, transfer or disposal of the signs. For more information, see the NRC website (http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/fs-tritium.html#_edn2). They are also subject to NRC or Agreement State inspection and enforcement action (including fines) for violating those requirements. Manufacturers must inform purchasers of the EXIT signs of the regulatory requirements for generally licensed devices. The general licensee is required to designate an individual responsible for complying with the regulatory requirements. Under NRC regulations, a general licensee using tritium EXIT signs: • must NOT remove the labeling or radioactive symbol, or abandon a sign; • must properly dispose of an unused sign (see below); • must report to the NRC or the appropriate Agreement State any lost, stolen or broken signs; • must inform the NRC or an Agreement State of a name change, change of address or replacement of a general licensee’s designated representative; • must NOT give away or sell the sign to another individual, company or institution unless the device is to remain in use at its original intended location; in such a case, the transferor is to notify the recipient of the regulatory requirements and must notify the NRC or Agreement State of the transfer within 30 days. Tritium EXIT signs must NOT be disposed of as normal trash. To dispose of a sign properly, a general licensee must transfer the sign to a specific licensee. This would typically be a manufacturer, distributor, licensed radioactive waste broker, or a licensed low-level radioactive waste disposal facility. These facilities may charge a fee for this service. Within 30 days of disposing of a sign, the general licensee is required to file a report to the NRC or Agreement State that includes: Regulatory information 74 • the device manufacturer’s (or distributor’s) name, model number and serial number; • the name, address, and license number of the person receiving the device; and • the date of the transfer. Reports should be sent to Director, Office of Federal and State Materials and Environmental Management Programs, ATTN: GLTS, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001. For more information, see the Fact Sheet on Tritium EXIT Signs on the NRC website (http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/fs-tritium.html).
