C H A P T E R Prepare for Router Installation Before you install the Cisco 900 Series Integrated Services Routers, you must prepare your site for the installation. This chapter provides pre-installation information, such as recommendations and requirements that should be considered before installing your router.
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 20A. Statement 1005 Warning Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018 Hardware Installation Guide for the Cisco 900 Series Integrated Services Router...
For altitudes above sea-level, de-rate the ambient operating temperature 1°C per 1000-feet of elevation. Note Cisco 900 series routers are fanless, normally run warm to the touch, and require adequate clearances for proper heat dissipation and ventilation. Site Selection Guidelines The Cisco 900 Series ISRs require specific environmental operating conditions.
Router Environmental Requirements Cisco 900 Series ISRs can be installed on a desk or a shelf, under a desk or a shelf, on a wall, and in a rack, depending on the SKU. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation.
(PWR-30W-AC(=)) • C927-4PM Network Cabling Specifications The following sections describe the cables and thee specifications required to install Cisco 900 Series ISRs: Console Port Connections The Cisco 900 ISR has both EIA/TIA-232 asynchronous (RJ-45) and USB2.0 compliant serial console ports.
For detailed information about installing a console terminal, see the Connecting to a Console Terminal or Modem section. For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document available on cisco.com.

C H A P T E R Install and Connect the Router This chapter describes how to install and connect Cisco 900 Series Integrated Services Router (ISR) to LAN and WAN networks. Warning Read the installation instructions before using, installing or connecting the system to the power source.
Cisco representative. Note Cisco 900 Series Routers are fanless. When stacking multiple Cisco 900 ISRs, ensure that there is ample surrounding space. Ample space, in turn, ensures more heat removal to enable the surrounding air temperature to stay within the specified operating conditions.
Before mounting the router on to the rack, refer to the following safety warning statements: Warning To prevent airflow restriction, allow clearance around the ventilation openings to be at least: 1.75 in. (4.4 cm). Statement 1076. Hardware Installation Guide for the Cisco 900 Series Integrated Services Router...

After the brackets are attached to the router, insert the router into the rack, and align the bracket in the rack. Use the machine screws to secure the router in the rack. Figure 13: Mounting the Cisco ISR 900 Series Router in a Rack Note Allow at least one rack unit (1RU) of vertical space between routers.
Install and Connect the Router Wall Mount Figure 14: Mounting the Cisco ISR 900 Series Router in a Tray Wall Mount Cisco 900 ISRs designed for wall-mounting (refer Table 6: Models and Mounting Options, on page 18) have mounting holes on the bottom of the chassis for securing with screws or anchors to a vertical surface.
Page 26
Wall Mount Step 1 Determine the required distance between mounting holes on the router. For Cisco 900 routers, the distance between mounting holes is 4.15 inches. Figure below shows the wall-mount holes located on the underside of the router. Figure 15: Router with Wall-mount Holes on the Underside Step 2 Use a 0.144-inch (3.7 mm) or a #27 drill bit to drill a hole in the wall.

Install and Connect the Router Ports and Cabling Ports and Cabling This section summarizes typical WAN and LAN connections for Cisco 900 Series ISRs. The connections summarized here are described in detail in the Cisco Modular Access Router Cable Specifications document on cisco.com.
The ROM Monitor software is also known as ROMMON, boot software, boot image, or boot helper. Although it is distributed with routers that use the Cisco IOS software, the ROMMON is a separate program from the Cisco IOS software. During normal startup, ROMMON initializes the router, and then, the control passes to the Cisco IOS software.
Page 38
ROMMON mode is a router mode, not a mode within the Cisco IOS software. The ROMMON software and the Cisco IOS software are two separate programs that run on the same router. At any given time, the router is running one of these programs, but it never runs both at the same time.
