Cisco 3200 Rugged Enclosures

This chapter provides an overview of the Cisco 3200 Rugged Enclosures so that simple troubleshooting, such as reconnecting a loose cable, can be performed in the field. The chapter is not intended as a complete guide to the chassis, because the devices should be serviced or repaired by a qualified personnel.

The enclosure seals the Cisco 3200 Series router cards so that they can withstand the harsh environments that are common in police cars, military vehicles, trains, airborne vehicles, and outdoor locations that are exposed to the elements.

Cisco 3200 Rugged Enclosure features include:

•Symmetrical mounting holes for the mounting brackets, so that the unit can be mounted upside-down if required.

•A design that meets NEMA4 requirements (impervious to rain or hose-directed water). The enclosure is slightly rounded on the top and bottom. This provides a non-pooling surface in case the enclosure is exposed to water.

•Maximum heat dissipation. Thermally conductive pads and thermal vias around the board perimeter of each card physically contact thermal plates that physically contact the aluminum chassis. This minimizes the overall board thermal rise by transferring heat into the surrounding environment.

The Cisco 3200 Rugged Enclosures are available as:

•A fully assembled Cisco 3270 Rugged Enclosure that supports the Cisco 3270 Rugged Router card, up to five mobile interface cards, and one Cisco Mobile Router Power Card (MRPC).

•A fully assembled Cisco 3230 Rugged Enclosure that supports the Mobile Access Router Card (MARC), up to five mobile interface cards (MICs), and one MRPC.

Figure 1-1 shows an exploded view of a Cisco 3230 Rugged Enclosure. (The design of the longer
Cisco 3270 Rugged Enclosure is similar.)

Cisco 3270 Rugged Enclosure

The Cisco 3270 Rugged Enclosure operates in a temperature range from -40 to +165°F (-40 to +74°C) when all ports are copper. If the Cisco 3270 Router includes a fiber-optic port, it operates at a temperature range from -40 to +147°F (-40 to +64°C).

The Cisco 3270 Rugged Enclosure is designed to meet NEMA4 requirements. Figure 1-2 shows an example of a fully assembled Cisco 3270 Rugged Enclosure. Note the greater length to accommodate the Cisco 3270 Rugged Router card and future expansion.

Figure 1-2 Cisco 3270 Rugged Enclosure

Cisco 3270 Router Card Stack

The Cisco 3270 Rugged Enclosure supports the following configurations:

•One Cisco 3270 Rugged Router card

•Up to three Wireless Mobile Interface Cards (WMICs)

•One Serial Mobile Interface Card (SMIC)

•One Fast Ethernet Switch Mobile Interface Card (FESMIC)

•One Cisco Mobile Router Power Card (MRPC)

A base configuration includes one of each of the following: Cisco 3270 Rugged Router card, SMIC, FESMIC, and MRPC.

In the Cisco 3270 Rugged Enclosure, the cards should be stacked in the order shown in Figure 1-3. The figure includes three optional WMICs. If WMICs are added, the first WMIC should be installed on the bottom of the stack, and the next two WMICs should be installed at the top of the stack.

Rugged Enclosure End Caps

Each Cisco 3200 Rugged Enclosure has two end caps: an antenna end cap that connects to the back of the enclosure, and an I/O end cap that connects to the front of the enclosure. The port configurations of the I/O end caps vary, based on the contents of the enclosure. For example, the number and location of antenna ports installed on the antenna end cap depend on how many WMICs are installed in the enclosure.

Note To prevent exposure to the elements, we recommend using the protective port covers (provided) on ports that are not in use and using port covers (provided) on the mating cables.

Antenna End Cap

The antenna end cap has four antenna ports on the flat side and two ports on the top surface. The end cap is used with the Cisco 3270 Rugged Enclosure or the Cisco 3230 Rugged Enclosure. The antenna ports are connector type RP-TNC. Each RP-TNC is connected internally to a WMIC. Typically, two antenna ports are used to support each WMIC. If fewer than three WMICs are installed, the unused antenna connector ports are sealed with a cap to protect them from the environment.

Figure 1-6 Cisco 3200 Rugged Enclosure Antenna End Cap with a Mounting Bracket

Note By default, the Cisco 3205 WMIC uses the right antenna to receive and transmit data.

Note For additional information on antennas and antenna cables, see the "Antenna Basics" technical note at http://www.cisco.com/en/US/products/hw/wireless/ps458/products_installation_guide_chapter09186a008007f74a.html
and the "Antenna Cabling" technical note at http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a00801c12c2.shtml

I/O End Caps for the Cisco 3200 Rugged Enclosures

The I/O end cap has multiple connectors for connecting power and data cables. The end cap configurations shown in this section are fully populated; however, the number of ports and their functions may differ, depending upon the number of WMICs in the system.

End Cap Fast Ethernet and WMIC Console Ports

Internally, five Fast Ethernet ports are available: one routed Fast Ethernet port on the router card and four switched Fast Ethernet ports on the Fast Ethernet Switch Mobile Interface Card (FESMIC). When a WMIC is installed in addition to the router, the WMIC Fast Ethernet port is connected internally to the routed Fast Ethernet port on the router card or is connected to one of the switched Fast Ethernet ports on the FESMIC to provide a communications link with the router. In contrast, the Serial Mobile Interface Card (SMIC) and FESMIC communicate with the router through the bus. All the router Fast Ethernet ports are addressed by using the slot/port format.

In typical configurations, the first WMIC Fast Ethernet port is connected to the routed Fast Ethernet port on the router card. The Fast Ethernet ports of the second and third WMICs are connected to FESMIC switched Fast Ethernet ports. The differences in the types of the router Fast Ethernet ports that the WMICs are connected to affect how they are configured, as, for example, when uploading a Cisco IOS image to a WMIC.

The WMIC runs an independent Cisco IOS image and when you configure the WMIC, the link forms an internal LAN. In standard configurations, the WMIC Fast Ethernet port is never brought out to the end cap.

The WMIC console port is brought out to the corresponding RJ-45 port on the I/O end cap, replacing a Fast Ethernet port. If the router includes one WMIC, the EIA/TIA-232 WMIC console port replaces a Fast Ethernet port on the end cap. If the router includes two WMICs, two WMIC EIA/TIA-232 console ports replace two Fast Ethernet ports on the end cap.

Note At present, even if the router contains no WMICs, in standard configurations the maximum three Fast Ethernet ports are brought out to the end cap. Unused EIA/TIA-232 ports are sealed.

¹The configuration of the port is set at the factory and labeled accordingly.

The RJ-45 connectors identified as 8, 9, and 10 are Fast Ethernet ports or WMIC console ports, depending on the configuration of the system. For example, if two WMICs have been added to the router, RJ-45 ports 8 and 9 are labeled WMIC 1 and WMIC 2. Port 10 is labeled FE1X.

Note The connectors are sealed at the factory with captive dust covers (not shown) that seal the ports and protect the pins. The dust covers should be used to seal the ports when the ports are not covered by cable connectors.

Fiber Optic Connector IP-67 Integrity

When the fiber-optic port is not connected or otherwise in use, the protective cover should be used to seal the port. To seal the fiber-optic port when it is connected to a cable, use connectors that maintain IP-67 integrity. The part numbers for the connectors are Tyco 1828618-1 and Tyco 1828618-2.

Caution When connecting fiber-optic cables, observe all standard procedures for safety, and maintain a clean connection.

Power Connector IP-67 Integrity

To seal the Tyco DC Power input power connector and maintain IP-67 integrity, use the following parts:

•796094-2-CPC housing

•66101-3-contact

•207489-1-boot

•207490-1-cable (grip size 11)

Smart Serial Port External Seal for System Integrity

When the Smart Serial port is not connected or otherwise in use, the protective cover should be used to seal the port. To seal the Smart Serial port when the port is connected to a cable, complete the steps in Appendix A, "Smart Serial Port External Seal." in the Cisco 3200 Series Router Hardware Reference.

USB Flash Storage Device Caveat

In some cases, using two USB flash storage devices causes unpredictable results (CSCsd11136).

If one USB flash storage device is plugged into a USB port and a second USB flash storage device is plugged into or unplugged from the other port, an error might occur (CSCsd44152). The error message is, "USB_HOST_STACK-6-USB_FLASH_READY_TEST_TIME: USB flash 'Ready' test time over
4 seconds."

If an unsupported USB flash storage device is plugged into a USB port, an error might occur (CSCsd44152). The error message is, "Failed to enumerate a USB device as not able to read the device's description."

To correct the problems, remove any unsupported USB flash storage device and use only one supported device in one of the two USB ports. The Cisco-supported flash storage devices listed below.

Protective End Cap Cover

A protective end cap cover ( Figure 1-9) provides weatherproof protection for the ports on the end caps of the Cisco 3200 Rugged Enclosure when the enclosure is installed outdoors. The protective end cap cover also provides added protection for in-vehicle use, inhibiting corrosion on the ports and potential damage from objects that are stored near the enclosure inside a vehicle.

The protective end cap cover has a ruggedized design for high reliability and NEMA4 compliance.

Step 2 Slide the hinge brackets onto the right side and the left side of the end cap cover. The mounting tabs should slide under the loosened bolts.

Step 3 Re-torque the two loosened bolts on the right side of the end cap cover to between 58 and 68 in-lb.

Step 4 Ensure that the gasket is fully seated in the protective end cap cover.

Step 5 Close the cover on the protective end cap cover and ensure that it is fully seated.

Step 6 Re-torque the end cap cover bolts on left side of the end cap cover to between 58 and 68 in-lb.

Step 7 Tighten the 8-32 protective cover screws (18 in-lb) until they are seated.

For sealing, we recommend Liquid Tight Connector, which is described at the following URL:

I/O End Cap Port Signals

This section describes the ports and port signals on the Cisco 3200 Rugged Enclosure I/O end caps.

Gigabit Ethernet Signal Limitations

Due to CPU and memory bus limitations, a Gigabit Ethernet port transmits and receives packets below the line rate. The line rate is lower for small frames and higher for large frames.

Small packet streams on Gigabit Ethernet ports, such as 64-byte packet streams, support up to 24 percent of full duplex, bidirectional line rate traffic without experiencing packet drops.

The 512-byte packet streams support up to 78 percent of full duplex, bidirectional line rate traffic. The 1518-byte packet streams support up to 88 percent of full duplex bidirectional line rate traffic.

At higher frame rates the RDRP receive drop counter (displayed by using the show controller g0/0 command) increases indicating dropped packets.

At higher frame rates for packet sizes greater than 512 bytes, the transmit underruns¹ counter (displayed by using the show int g0/0 or show int g0/1 command) increases. The transmit underruns might cause CRC errors on the peer router.

Fast Ethernet Signals

A Cisco router identifies a Ethernet port interfaces by slot number and port number in the format of slot/port. For example, the slot/port address of a Fast Ethernet interface on the Cisco 3230 Rugged Enclosure is 0/0.

The Cisco 3270 Router Ethernet port signals are in compliance with IEEE 802.3. The interfaces support the following:

•Autonegotiation and parallel detection MII interface with extended register capability for 10/100BASE-TX or 10/100/1000BASE-TX connections.

•Full-duplex and half-duplex modes.

•3.3V operation low power consumption (300 mW typical).

•Low-power sleep mode.

•Robust baseline wander correction performance.

•MDIX support (Fast Ethernet and Gigabit Ethernet copper only).

•Jumbo Frame (4400 bytes) support on Gigabit Ethernet interfaces.

•10BASE-T or 100BASE-TX using a single Ethernet connection.

•10BASE-T, 100BASE-TX, or 1000BASE-TX using a Gigabit Ethernet copper connection.

•100BAFX/100LX, 1000BASE-SX, 1000BASE-LX/LH for Gigabit Ethernet fiber-optic connections. (The speed is not configurable.)

•Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation.

•Integrated programmable LED drivers.

Fast Ethernet Port Cabling for the Cisco 3250 and Cisco 3230 Routers

Most Cisco 3200 Series router Ethernet ports support autodetection. If the device that the router is connected to also supports autodetection, the choice of a straight-through or crossover Ethernet cable does not matter. However, the Cisco 3250 router MARC FE0X port does not support autodetection.

To connect a port marked MARC FE0X to a routing Ethernet port that does not support autodetection, use a straight-through Ethernet cable. To connect a MARC FE0X port to a hub, switch, a router hub, or switch port, use a crossover Ethernet cable. Table 1-1 shows the connections.

Table 1-1 General Guidelines for MAR Fast Ethernet Port Cabling

Crossover cable

Straight-through cable

For example, a port marked FE0X requires a crossover Ethernet cable to establish the Ethernet link between a Cisco 3250 router and a hub. A port that does not support autodetection marked FE0 requires a straight-through Ethernet cable to establish the Ethernet link between a Cisco 3250 router and a hub.

For additional information on cable pin assignments, see the "Cable Pinouts" chapter of the Cisco Content Services Switch Getting Started Guide at:

http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_installation_guide_chapter09186a00805f718d.html

Console Port Signals

You can connect to the router or to a Wireless Mobile Interface Card (WMIC) by using a console cable to connect to the console interfaces.

The console port signals:

•Are asynchronous serial DCE

•Support 9.6-kbps, 19.2-kbps, 38.4-kbps, 57.6-kbps, and 115.2-kbps baud rates

•Support full modem control of DTR, DSR, RTS, and CTS signals

AUX Port Signals

The AUX port is a serial asynchronous port that supports the following speeds:

•Cisco 3270 Rugged Router card in the Cisco 3270 Router: 1.2 kbps, 2.4 kbps, 4.8 kbps, 9.6 kbps, 19.2 kbps, 38.4 kbps, 57.6 kbps, 115.2 kbps, and 460 kbps.

•Mobile Access Router Card (MARC) in the Cisco 3230 Router: 1.2 kbps, 2.4 kbps, 4.8 kbps, 9.6 kbps, 19.2 kbps, 38.4 kbps, 57.6 kbps, and 115.2 kbps.

The AUX port supports the following:

•Asynchronous serial DTE

•5 to 8 data bits

•1, 1.5, or 2 stop bits

•Odd, even, or no parity

•Flow control by using RTS, CTS, DTR, and CDC signals

Mounting Brackets

Mounting brackets are available for the enclosures.

The notches in the mounting brackets allow you to temporarily install the bracket without the router in place. The bolts for the notches in the mounting bracket can be installed on the enclosure before the other bolts are installed. The partially installed bolts provide enough support to allow you to install the router in the bracket, and then install and tighten the remaining bolts. The torque values for the mounting bracket screws are from 58 to 68 in-lb.
