Chapter 1 Overview of the Cisco MWR 1900 Router Compact Flash Compact Flash One external Compact Flash (CF) device is used on the MWR 1900 router. The CF memory size can vary with a minimum size of 32Mbyte and a maximum size of 128Mbytes. This device is configured in memory mapped mode (PCMCIA) to allow for hot insertion. This device is required for the MWR 1900 router to function because the IOS image and troubleshooting logs reside on this device.
Chapter 1 Overview of the Cisco MWR 1900 Router Environmental Monitoring Temperature Sensor Environmental Monitoring Temperature Sensor The MWR 1900 router has a temperature sensor to detect over-temperature conditions inside the chassis. The over-temperature detection trips at 75°C +/- 5%. This condition is reported to the processor as an interrupt and software then takes action on this interrupt to generate the appropriate alarming.
C H A P T E R 2 Preparing to Install the Router This chapter describes site requirements and equipment needed to install your Cisco MWR 1900 router.
Chapter 2 Preparing to Install the Router Safety Recommendations Safety with Electricity Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Warning This unit is intended for installation in restricted access areas.
Chapter 2 Preparing to Install the Router General Site Requirements – If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help. – Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action. General Site Requirements You can mount the Cisco MWR 1900 router in a 19-inch rack (with a 17.5- or 17.75-inch opening).
Chapter 2 Preparing to Install the Router Inspecting the Router • #6, ring-style ground lug. • 18-AWG copper wire for the power cord. • Wire-stripping tool(s) for stripping both 6- and 18-gauge wires. Inspecting the Router Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to install the router, proceed with unpacking it.
Chapter 2 Preparing to Install the Router Installation Checklist Installation Checklist The sample Installation Checklist lists items and procedures for installing a new router. Make a copy of this checklist and mark the entries when completed. Include a copy of the checklist for each router in your Site Log (described in the next section, “Console and Auxiliary Port Considerations”).
Chapter 2 Preparing to Install the Router Console and Auxiliary Port Considerations Console and Auxiliary Port Considerations The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the router either locally using a console terminal, or remotely using a modem connected to the auxiliary port.
C H A P T E R 3 Installing the Router This chapter describes how to install your Cisco MWR 1900 router and connect it to networks and external devices.
Chapter 3 Installing the Router Connecting the Console Terminal and Modem Attaching the Brackets Attach the mounting brackets to the chassis as shown, using the screws provided in the bracket kit. Attach the second bracket to the opposite side of the chassis. Use a number 2 Phillips screwdriver to install the bracket screws. Four screws are required on each side. Figure 3-1 shows how the bracket is attached.
Chapter 3 Installing the Router Connecting the Console Terminal and Modem These ports provide administrative access to your router either locally (with a console terminal) or remotely (with a modem). Identifying a Rollover Cable Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable.
Chapter 3 Installing the Router Connecting the Network Cables Note Because hardware flow control is not possible on the console port, Cisco does not recommend that modems be connected to the console port. Modems should always be connected to the auxiliary port. Auxiliary Port Take the following steps to connect a modem to the auxiliary port on the router: Step 1 Connect a modem to the auxiliary port using an RJ-45 rollover cable with an RJ-45-to-DB-25 adapter. The provided adapter is labeled MODEM.
Chapter 3 Installing the Router Connecting the Network Cables RJ-45 Port and Plug H2936 Figure 3-3 87654321 RJ-45 connector Table 3-1 lists the pinouts and signals for the RJ-45 port. Table 3-1 RJ-45 Pinout Pin Description 1 Receive Data + (RxD+) 2 RxD- 3 Transmit Data + (TxD+) 6 TxD- Connecting the VWIC Interface Cables How you connect the ports of the T1/E1 Multiflex VWIC depends on whether you are using the MWR 1900 router in a redundant or a non-redundant configuration.
Chapter 3 Installing the Router Connecting the Network Cables Note If you choose to use the T1/E1 Multiflex VWIC in a non-redundant configuration, you must close the relays on the card using the standalone subcommand. For more information, see the “Cisco MWR 1900 Software Configuration Guide.” Step 1 Confirm that the router is turned off. Step 2 Connect one end of the cable to the T1 or E1 port on the card. Step 3 Connect the other end to the BTS patch or demarcation panel at your site.
Chapter 3 Installing the Router Connecting the MWR 1900 Router to a DC-Input Power Supply This section describes the specifications of the Y-cable. • T1/E1 Multiflex VWIC Y-cables should be made with 4 twisted-pair, shielded, 28-gauge cables. • The cable length of each stub (from the RJ-48C connector to the junction point) should not exceed 3 inches (76 mm). • The cable length from junction point to the patch panel is determined by the customer.
Chapter 3 Installing the Router Connecting the MWR 1900 Router to a DC-Input Power Supply • 18-AWG copper wire for the power cord. • Wire-stripping tool(s) for stripping both 6- and 18-gauge wires. Grounding the Router Follow these steps to ground the router to earth ground. Make sure to follow any grounding requirements at your site. Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Chapter 3 Installing the Router Connecting the MWR 1900 Router to a DC-Input Power Supply Step 6 Use the screw to attach the ground lug and wire assembly to the rear panel of the switch. Step 7 Using a ratcheting torque screwdriver, torque the ground-lug screw to 15 1bf-in (or 240 ounce-force inches [240 ozf-in]). Wiring the DC-Input Power Source Warning Note This product relies on the building’s installation or power supply for short circuit (overcurrent) protection.
Chapter 3 Installing the Router Replacing or Upgrading the CF Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected.
Chapter 3 Installing the Router Replacing or Upgrading the CF Note Ensure that the IOS image is the first file on the CF. Otherwise, the router will not boot. To avoid naming conflicts, we recommend that you copy the file as mwr1900-i-mz.boot. Step 9 Reboot the system to the ROMMON prompt. Step 10 Boot the customer-ordered IOS image from the new CF. Step 11 Upon successful booting of the image, replace the CF cover. If the boot process is unsuccessful, repeat Step 6 through Step 10.
Chapter 3 Installing the Router Replacing or Upgrading the CF Formatting Procedures for CF Memory Cards For the Cisco MWR 1900 router, Cisco recommends that you format/erase new CF memory cards to initialize them with a Class C Flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the Flash.
Chapter 3 Installing the Router Replacing or Upgrading the CF The following example shows output for copying a Cisco IOS file from an external CF memory card to a TFTP server: Router# copy slot0:mwr1900-i-mz.tmp tftp: Destination filename [mwr1900-i-mz.
Chapter 3 Installing the Router Replacing or Upgrading the CF The following example shows output for displaying the geometry and format information of an external CF memory card formatted with a Class C Flash file system: Router# show slot0: ******** ATA Flash Card Geometry/Format Info ******** ATA CARD GEOMETRY Number of Heads: 2 Number of Cylinders 490 Sectors per Cylinder 32 Sector Size 512 Total Sectors 31360 ATA CARD FORMAT Number of FAT Sectors Sectors Per Cluster Number of Clusters Number of Data
Chapter 3 Installing the Router Replacing or Upgrading the CF Display File Content To display the content of a file in a CF memory card, use the more slot0: filename command. The following example shows output from the more command on an external CF card: Router# more slot0:mwr1900-i-mz.
Chapter 3 Installing the Router What to Do After Installing the Hardware Router# cd slot0:/config Router# dir slot0: Directory of slot0:/config/ 1581 drw- 0 Mar 01 1993 23:50:08 test-config 128094208 bytes total (121626624 bytes free) Remove a Directory To remove a directory from CF memory, use the rmdir slot0:/directory-name command. Before you can remove a directory, all files and subdirectories must be removed from the directory.
