Q. Is the AC power adapter IP41 rated?
A. The Cisco 819 ISR AC power adapter is not IP41 rated. Installation must include protection from the power
adapter and power plug from water.
Q. What is DC power adapter IP rating?
A. The DC power adapter for the Cisco 819HG and 819G is not IP41 rated. It is IP41 rated for Cisco 819HGW
ISRs. Martek railway DC power adapter is IP65 rated.
Q. What are the DC power adapter mounting options?
A. The DC power supply may be mounted to a wall using four #6 pan or round-head wood screws for the
mounting holes on the supply. Each mounting screw must go into a wall stud (wood) or a wall anchor of the
appropriate type for the wall. Screws into the drywall are not sufficient to support the DC power supply. Please
refer to the Cisco 819 Integrated Service Router Hardware Installation Guide for installation instructions.
Q. What is the power cord retention lock?
A. The Cisco 819 ISRs have a power cord retention mechanism as an accessory. It locks the power cord to the
router so when a user accidentally pulls out the power cord, the power cord will not come out from the router.
For the complete list of Cisco 819 ISRs that support power cord retention lock, it is available in Cisco
819HGW, 819HWD, and 819H routers. Refer to the Cisco 819 Integrated Service Router Hardware Installation
Guide for installation of retention lock.
Q. What is the power switch lock?
A. The Cisco 819 ISRs have a power switch lock as an accessory. The power switch lock prevents unauthorized
access to a tampered router (for example, router in a bus). It is available in Cisco 819HGW, 819HWD, and
Cisco 819H routers. Please refer to the Cisco 819 Integrated Service Router Hardware Installation Guide for
installation of the power switch lock.
Q. What is the power consumption for Cisco 819 ISRs?
A. Cisco 819 Wi-Fi ISRs have maximum power consumption of 20W, other non Wi-Fi Cisco 819 ISRs have a
maximum power consumption of 11W.
Q. What LEDs are available on Cisco 819 ISRs?
A. The LEDs are located at the front panel of the Cisco 819, which include SYS, ACT, WWAN, GPS, RSSI, SIM,
3G, and WLAN. Please refer to the Cisco 819 Integrated Service Router Hardware Installation Guide for
detailed LED behavior.
Q. What are the memory options of Cisco 819 ISRs?
A. The Cisco 819G and 819HG support fixed 512-MB DRAM 256-MB Compact Flash. The Cisco 819HGW,
819HWD, and 819H support fixed 1-GB DRAM and 1-GB Compact Flash in IDE mode.
Q. What is the mean time between failure (MTBF) of Cisco 819 ISRs?
A. Cisco 819 MTBF is calculated based on ground benign condition. Please refer to the Cisco 819 Integrated
Service Router Hardware Installation Guide for the MTBF value of each SKU.
