• Labeling on patch panel is just room number and port number in that room.

• The label will include a designation for whether it is a data line or dedicated voice line with a corresponding “-D” or “-V”. VoIP lines will not be considered to be dedicated voice lines.

• Example, see Figure 2-3 Patch Panel Sample.

o 4L123 is the room number where the far end of the cable is terminated.

o “1A-D” = port A on wall plate number 1, Data jack o “2B-D” = port B on wall plate number 2, Data jack o “1D-V” = port D on wall plate number 1, Voice jack.

3 Rack Management

3.1 Main Distribution Frame (MDF)

The MDF is the cable rack that interconnects the telecommunication wiring between the private or public lines coming into the building with the internal network. In the MEPS, the incoming connections include telephone lines and the connection to the Recruiter Service Network (RSN). The MDF coordinates and connects these lines to the internal hardware.

For the network connections, the RSN connection enters the building in the demarc location, and is connected to the RSN Router (Cisco 2821, to be upgraded to Cisco 3845). This router is connected to the Cisco 45xx switch, for distribution throughout the building.

The network topology at a MEPS is a star configuration. In general, each workstation and server is connected to the network by a cable that runs back directly to the 45xx switch in the MDF. In a few locations, there is an Intermediate Distribution Frame (IDF) that serves a portion of the building. In this case, a single uplink line connects the MDF switch to a second switch in a different location of the building. This second switch is then connected to workstations in a star topology.

Patch panels are used to add a layer of abstraction between the switch and the horizontal cable runs to the workstations. Each workstation cable run terminates at the back of a patch panel in the rack. Patch cables then connect the front of the patch panel to a port on the switch.

It is important to keep the wiring of the patch cables neat and organized. Ideally, patch cables should run from the switch port to the nearest side of the rack, bundled carefully with Velcro to keep them organized but not kinked. In this way, half the cables would transit the left side of the rack, and half to the right. Then the patch cables should run vertically to the designated patch panel. Then the cables should again run horizontally to the corresponding patch panel.

Patch cables should not be excessively long. They should traverse the distance necessary with a minimum of slack.

Cable management systems on the sides of the rack aid in managing the vertical cable runs.

Cable lengths can be kept to a minimum and the vertical runs kept less cluttered by locating the switch near the center of the rack, and locating 4 patch panels above the switch, and 3 patch panels below. However, since the 65xx switches are heavy, keeping them at the bottom of the rack is also acceptable.

A minimum of cable clutter will aid in managing the MDF during future modifications, aid in increasing airflow to the heat-generating components and enable port and cable labels to be more easily read.

“MEPS with 2 and/or 3 6509 Switches” Some MEPS could have 2 or 3 6509 Switches.

1: Port 5/8 on switch#1 is the down stream link to the second switch#2 Port 5/8.

2: Port 5/7 on switch#2 is the down stream link to the third switch Port 5/7.

Figure 3-2 MEPS MDF, Multiple-Switch

This is the target configuration for a MEPS MDF where the facility requires more than one distribution point. This is the case for MEPS with multiple floors or where the facility is too spread out to support Ethernet cable runs from only the main MDF. This configuration shows a typical layout of the racks containing the network hardware and patch panels.

Refer to Section 2.4, “MEPCOM Specific Equipment-Related Cabling Requirements” for more configuration constraints.

3.1.3 MEPS MDF Equipment

The table in Figure 3-3 contains a list of equipment deployed to the MEPS as part of the MDF, and network infrastructure.

3.2 Best Practices

3.2.1 General Rack Management Best Practices

• Color coding o By subsystem o By connection type: Workstation, switch, server, internet

• Avoid bending cables too far. They should not be bent to the point of creasing the sheathing.

• Label all cables and components

• Organize cables to separate data from power as much as possible.

• Keep data and power cables from obstructing the flow of air within the cabinet.

• Data cables should run up and overhead, power should be run down to the floor.

• Use Velcro instead of cable ties.

Figure 3-4 Cable Ties

The crimping of cable insulation as shown in Figure 3-4 should be avoided..

3.2.2 MEPS MDF, Examples

Figure 3-5 below shows a typical MDF rack. However, there are a number of issues with this rack.

• Patch cables are unnecessarily long

• Some patch cables are not adequately organized (especially the yellow ones)

• Patch cables are bound with plastic zip ties, crimping the cable sheathing.

• Unused equipment is still located in the racks

• A number of cables are dangling loosely

• There appear to be unused cables dangling from the rack

• Ideally, vertical cable management systems would be implemented on the sides of the rack to aid with cable organization.

Figure 3-5 Example MDF rack, with issues

Figure 3-6 below shows a well-organized MDF rack.

• Cables are well organized and neat

• Adequate space is available to access the rear of the rack

• Vertical cable management systems are used
