Carrier Grade Updates for Dell

PowerEdge R720 and R620 Systems

Important Information

WARNING: The intra-building port(s) of the equipment or subassembly is suitable for

connection to intra-building or unexposed wiring or cabling only. The intra-building

port(s) of the equipment or subassembly must not be metallically connected to

interfaces that connect to the Outside Plant (OSP) or its wiring. These interfaces are

designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described

in GR-1089-CORE, Issue 5) and require isolation from the exposed OSP cabling. The

addition of Primary Protectors do not provide sufficient protection to connect these

interfaces metallically to the OSP wiring.

WARNING: The intra-building port(s) of the equipment or subassembly must have

shielded intra-building cabling or wiring that is grounded at both ends.

• Network equipment — Includes standard PCIe based Network Interface Card

(NIC) and Fibre Channel (FC) devices.

• Bonding network — Equipment is suitable for Common Bonding Networks

(CBNs).

• Suitable installation location — Equipment is suitable for installation in

Network Telecommunications Facilities (NTF), and locations where the

National Electrical Code (NEC) is applicable.

• DC bonding — Equipment is suitable for DC common bonding installations.

• Fan filter — The filter material in the filter bezel is a 0.25 inch thick, 25 PPI

foam, and has an ASHRAE dust by weight arrestance of 66%. The filter must

be replaced on a quarterly basis.

NOTE: You can order a service kit containing four replacement filters by

contacting Dell Support.
