Chapter 2 J-series Services Router Hardware Features J-series Services Routers running JUNOS software with enhanced services have chassis that are similar but with important differences. J2320, J2350, and J4350 routers have a single nonredundant power supply and an optional Crypto Accelerator Module.
J2320 and J2350 Chassis The J2320 and J2350 chassis is a rigid sheet metal structure that houses all the other router components (see Figure 1 on page 8 through Figure 7 on page 11). The chassis can be installed in many types of racks or cabinets. For information about acceptable rack types, see “ Rack Requirements ” on page 64.

Chapter 4 Preparing for Router Installation Before installing a J-series Services Router, make sure that your site has the proper operating environment and equipment.
Rack Requirements J-series Services Routers must be installed in a rack. Many types of racks are acceptable, including front-mount racks, four-post (telco) racks, and center-mount racks.
The J2320 chassis height of 1.75 in. (4.45 cm) equals 1 U. The J2350 chassis height of 2.61 in. (6.63 cm) equals 1.5 U. Each U is a standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.
Router Environmental Tolerances Table 34 on page 66 specifies the environmental conditions required for normal Services Router operation. In addition, the site must be as dust-free as possible. Dust can clog air intake vents, reducing cooling system efficiency.
Then, use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire. For more information about fire extinguishers, see “ Fire Suppression Equipment ” on page 67.
Site Electrical Wiring Guidelines WARNING: Certain ports on the router are designed for use as intrabuilding (within-the-building) interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE , Issue 4) and require isolation from the exposed outside plant (OSP) cabling.
CAUTION: To comply with intrabuilding lightning/surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends. Router Power Requirements Table 35 on page 69 and Table 36 on page 69 list the AC and DC power system electrical specifications for Services Routers.
Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the Services Router. The appliance coupler at the female end of the cord inserts into the appliance inlet on the faceplate of the AC power supply. The coupler is type C19 as described by International Electrotechnical Commission (IEC) standard 60320.
For information about the AC power supply, see “ J2320 Power System ” on page 18, “ J2350 Power System ” on page 18, “ J4350 Power System ” on page 30 or “ J6350 Power System ” on page 31. To connect the power cord during initial installation, see “ Connecting Power ” on page 84.
NOTE: Power cords and cables must not block access to router components or drape where people might trip on them. For information about the DC power supply, see “ J2350 Power System ” on page 18, “ J4350 Power System ” on page 30 or “ J6350 Power System ” on page 31.
