Standard Configuration

ITS is currently installing Cisco Catalyst switches. The standard configuration for DLs currently being deployed and financed by the Core Network Funding Model are listed below.

Note: Funding for secondary switches or non-standard configurations for primary or secondary switches are the responsibility of the unit.
Physical Characteristics
  • Height: desired: 1-2 Rack Units (RUs), 4RU maximum
  • Width: 19" (maximum)
  • Depth:
  • Physical Ports:
    • Minimum of 24 SFP (Gigabit Ethernet) w/ ability to support 10/100 Copper SFPs.
    • Support for 3rd party SFPs desirable.
    • This is based on a average of one 1GE per LDF.
    • Fewer ports may be warranted in buildings where the DL and AL is the same box.
    • For those buildings requiring more ports additional chassis can be clustered/stacked.
    • Upgradable to 2 - 10GE ports.
  • Console port
  • Power: 110VAC/20Amp
  • Redundant power supply (required in absence of second DL)
  • Stacking/Clustering capability to create one virtual DL from multiple chassis.
    • Minimum Interconnect speed of 32 Gbps
