CHAPTER
1
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.

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.
NoteTo 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.

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.
Chapter 1 Cisco 3200 Rugged Enclosures
1-8
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.
NoteAt 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.

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.

Step 1Loosen the end cap mounting hardware (four 1/4-20 bolts), but do not remove the bolts.
Step 2Slide 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 3Re-torque the two loosened bolts on the right side of the end cap cover to between 58 and 68 in-lb.
Step 4Ensure that the gasket is fully seated in the protective end cap cover.
Step 5Close the cover on the protective end cap cover and ensure that it is fully seated.
Step 6Re-torque the end cap cover bolts on left side of the end cap cover to between 58 and 68 in-lb.
Step 7Tighten the 8-32 protective cover screws (18 in-lb) until they are seated.

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 intg0/0 or show intg0/1 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.

1. Transmit underrun–an error on interfaces when the data is not ready on the memory bus when the system
attempts to transmit the data; a bad packet is transmitted.

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
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.
3250 router MARC FE0X port does not support autodetection.
