Last Revised: January 11, Caution The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms Mohm. Timesaver If the slot adapter is already installed against the right side wall of the router chassis, skip this step. Caution The double-wide and extended double-wide network modules can be heavy. Avoid touching the network module board to support the module.
Handle the network module by the faceplate only to avoid damage to board components. Caution To avoid damaging the network module, always handle the network module by the handle or faceplate. Do not touch the circuit board. If you remove a network module, install the same model network module in its place.
For 1- or 2-slot network modules, you must install the same network module and interface card combination. Caution Do not perform OIR on interface cards in 1- or 2-slot network modules.
To avoid damage to the interface card and to the network module, turn off electrical power and disconnect network cables before inserting an interface card into a network module slot. Router config-if shutdown.

Heat generated by equipment at the bottom of the rack can be drawn upward into the intake ports of the equipment above it. If you have installed the chassis using slide rails, check for blocked ventilation ports when it is in position in the rack or cabinet. Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet. The best location for the baffles depends on the airflow patterns in the rack.
You can test the airflow by experimenting with different equipment arrangements. Statement — Clearance Around the Ventilation Openings. To prevent airflow restriction, allow clearance around the ventilation openings to be at least:1 in The location of your hardware and the layout of your equipment rack or wiring room are extremely important considerations for proper operation.
Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear panels of the hardware. When planning your site layout and equipment locations, refer to the General Site Requirements section. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions and recommendations may help you to isolate the cause of failure and prevent future problems.
Ensure that the room where your voice gateway operates has adequate air circulation. Electrical equipment generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures. Always follow the ESD-prevention procedures to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment failure. Ensure that the chassis cover and the module rear panels are secure. All empty network module slots, interface card slots, and power supply bays must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings permits air leaks, which may interrupt and reduce the flow of air across internal components.
Baffles also help to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack. Find the best placement by experimenting with different configurations.
If an equipment installed in a rack particularly in an enclosed rack fails, try operating the equipment individually. Power off other equipment in the rack and in the adjacent racks to allow the hardware maximum cooling air and clean power.
Check the power at your site to ensure that you are receiving clean power free of spikes and noise. Install a power conditioner, if necessary. To handle power failure conditions, an uninterrupted power supply UPS is needed.
For more information on power supply, see Power Supplies chapter in this guide. To reduce risk of electric shock or fire, ensure that the protective device is rated not greater than 20A.
To reduce risk of electric shock and fire, you must incorporate a readily accessible two-poled disconnect device in the fixed wiring. When you run cables for any significant distance in an electromagnetic field, interference can occur between the electromagnetic field and the signals on the cables. This has two implications for the installation of terminal plant cabling:. If you use twisted-pair cables with a good distribution of grounding conductors in your plant cabling, emitted radio interference is unlikely.
If you have cables exceeding recommended distances, or if you have cables that pass between buildings, give special consideration to the effect of lightning strikes or ground loops. If your site has these characteristics, consult experts in lightning suppression and shielding. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices.
Most data centres cannot resolve such infrequent but potentially catastrophic problems without pulse meters and other special equipment. Take precautions to avoid these problems by providing a properly grounded and shielded environment and by installing electrical surge suppression.
If you remove any module, you must either install a module in its place or install a cover plate over the opening.
All module openings must be either occupied or covered to prevent electromagnetic interference. For advice on the prevention of electromagnetic interference, consult experts in radio-frequency interference RFI. You need the following tools and equipment to install and upgrade the voice gateway and its components:.
Standard flat-blade screwdriver as required for attaching the brackets for rack mounting. Four telco machine screws, for installing the chassis in a rack use the screw size required by the rack. We recommend that you maintain a site log to record all actions relevant to the system.
A site log typically includes:. Installation - Print a copy of the installation checklist and insert it into the site log. Upgrades and maintenance - Use the site log to record ongoing maintenance and expansion history.

See the Installing Cisco Interface Cards in Cisco Access Routers document, for instructions that describe how to install legacy interface cards in the router.
Note See the r outer product page at cisco. Depending on the model that you have purchased, the routers use a CompactFlash or an eUSB flash for the internal bootflash memory. The CompactFlash is located behind the fan tray on the router chassis.
It supports 8GB or 16GB. The use of any other cards during normal network operation can affect system performance or reliability. Note Do not run the router without a CompactFlash card installed. Note Depending on the model that you have purchased, the routers use a CompactFlash, or an eUSB flash for the internal bootflash memory.
However, you can use the old CompactFlash that is available with the routers. The NIM can be installed in any bay slot 0. The SSDs are hot-swappable as part of normal operation. This device is not hot-swappable and requires opening the chassis to service or upgrade. Cisco ISR platform supports an optional internal M2. SSD with the capacity of G. The PVDM4 is installed inside the chassis of the router.
The routers contain the following types of memory:. The control plane uses two DIMMs and they must be exactly the same type and density. The routers support a variety of power supply configurations. The power supplies module are field-replaceable and externally accessible.
Cisco ISR power supply module is inside the chassis. Table summarizes the power options. Router and chassis temperature is regulated with internal fans. An onboard temperature sensor controls the fan speed. The fans are always on when the router is powered on. Under most conditions, the fans operate at the slowest speed to conserve power and reduce noise.
When necessary, the fans operate at higher speeds under conditions of higher ambient temperature. In most cases, the router designates its interfaces using a 3-tuple notation that lists the slot, bay, and port. The 3-tuple value is zero based. This refers to slot 0, the second bay in slot 0 the first bay is 0 so the second bay is 1 , and the third port in bay 1.
See Table for more examples. This port is the only 1-tuple port on the system. IEC , Safety of information technology equipment [world-wide]. EN , Safety of information technology equipment [EU]. EN Electromagnetic compatibility - Generic immunity standard - Part 1. EN V1. To minimize the negative impact of environmental dust or debris, we recommend periodic inspection and cleaning of the external surface of the router.
The frequency of inspection and cleaning is dependent upon the severity of the environmental conditions, but we recommend a minimum frequency of every six months.
Cleaning involves vacuuming of router air intake and exhaust vents. Skip to content Skip to search Skip to footer. Book Contents Book Contents.
