![]() ![]() For example, it is a frequent practice for visitors to sneak in food. In other instances, inmates may coerce the staff in carrying contraband into prisons by posing threats of violence against friends or family members.Ĭontraband could also get their way into prisons through visitors. For a number of prison staffs, extra cash by the end of the month could be a powerful temptation in a poorly paying job. A common way is the offers that inmates make in return for them to offer voluntary services for acquiring and sneaking contraband. There are a number of ways in which prisoners can get staffs to carry out the task of smuggling contraband. It is especially problematic because of the staff's involvement in contraband smuggling. Contractors, inmates, visitors, and even staffs have a hand in getting into prison contraband, and they get into the prison premises in conceivable ways (Blackburn, Shannon, and Pollock 111). There are several means through which inmates can access contraband in prisons. Other items such as materials to make homemade ropes or buffer cords, maps, dummies, and unauthorized clothing pose the danger of facilitating the escape of inmates. These items, in addition to drugs and alcohol, can cause great havoc and pose a potential danger to staff and other inmates. A number of staffs who work in prisons are acutely aware of the destruction that these items are likely to cause. Weapons and escape materials are both dangerous in the correct circumstances. ![]() Any other thing, aside from these that a prisoner possesses are contraband. A number of these facilities allow their inmates to buy items from the commissary or receive other articles or items through other authorized channels. All correctional facilities provide their inmates with room and board, clothing, medical care, and basic hygiene items. Contraband is any item that a prisoner is not allowed to possess (Frantz 178). Controlling contraband should be the top priority of any prison management, regardless of the level of security. ![]()

![]() Set Max MTU to 1492 (rather than the disabled default of 1500).Two must do’s for this router to unblock Outlook sending emails are: I went through the RMA process and am awaiting a replacement unit.Īfter dusting off and setting up my old Linksys wireless-B BEFW11S4 router, all was well again… except for Outlook not being able to send out any emails! After some quick research, it turns out that the BEFW11S4 has been well documented to have email send issues. Once they receive the defective unit, the credit card hold will be cancelled. The only difference is when you choose the cross shipment method, Linksys will put a hold on your credit card for the retail amount of the unit that they have sent you. After you receive the replacement, you simply send back the defective unit as opposed to having to send in your unit first before Linksys sends you another. Cross shipment is where Linksys sends you a replacement unit first. The WRT54GL has a 3 year warranty so I chose the cross shipment method for replacement. It got to the point that every 24 hours, the router needed a hard reset and a full re-setup to work properly again. After some usage, the DNS drop would return. Of course, after each tedious call, the router would work fine. Linksys is sending a replacement unit.ĭuring each call, tech support suggested changing MTU settings, disabling Block Anonymous Internet Requests, hard resetting the router, re-flashing the firmware, power cycling the modem & router, running static IP & DNS settings on each computer, adjusting various wireless settings, etc…. After 2 weeks of tech support calls and more than 4 hours of total support time, the effort finally paid off. In short, I can see and access other computers in the local area network, but there is no internet connection. Thought I would share a quick fix and save some of you from hours of hair pulling.įor one reason or another, my Linksys WRT54GL wireless-G router began intermittently dropping DNS connections (4.2.2.2) even though the default gateway (192.168.1.1) respond normally to pings. I actually experienced this recently – what a mess. If you find that Windows Mail has incorrectly identified a message as spam, and your settings are such that Junk mail is moved to the Junk folder, use the Not Junk button to restore messages to the Inbox.There have been quite a few complaints that Outlook 2007 (running in Windows Vista) is not sending out emails properly when paired with certain Linksys routers.You may wish to place a check in the box labeled move phishing E-mail to the Junk Mail folder, but be sure to check your Junk Mail folder once in a while for false-positives. Microsoft has included anti-phishing filters as a part of Windows Mail. One default setting that you might want to change is the Automatically add people I e-mail to the Safe Senders List, which is turned off by default. Only use this option if you know exactly who will be sending you email messages. The final option is to only accept email from people (or domains – like ) that you specify (your safe senders list). Also, it’s a very good idea not to permanently delete suspected junk e-mail instead of moving it to the junk email folder, because there’s a very good chance you’d be automatically deleting messages that are not spam. See step 5 below for information on restoring legitimate email from the Junk folder. If you choose the high setting, be sure to check your Junk E-mail folder fairly often to make sure no actual messages were incorrectly flagged. If you get a fair bit of spam and are willing to put up with the occasional legitimate email being marked as Junk (which is called a false-positive), you might want to switch to the High level of filtering. The default is Low, which means that when Windows Mail isn’t totally sure if something is spam, it will ‘play it safe’ and leave the message alone (which is to say it will put the message in your Inbox rather than filter it as Junk). On the Options tab you’re presented with the different ‘levels’ of spam filtering that Windows Mail offers. ![]()
![]() ![]() It’s uncommon for a solar panel to fail as they’re meant to last 25 years in the field. If your system was professionally wired, chances are that you may not experience this problem, but it is worth checking for. You can use a multi-meter to check the voltage levels at various points to find out the point beyond which the problem of low voltage begins. If the modules are not overheated, the best bet for you will be to check for a bad connection. Also, make sure that there’s sufficient air circulation beneath the panels and that this open space is not blocked in any way. Adding more modules in series, and therefore increasing the string voltage, will eliminate this problem. The higher the temperature, the lower will be the power output. ![]() It has been scientifically proven that the voltage drop rises with the rise in temperature. If shading is not an issue, most likely it will be the higher than normal operating temperature of the solar panels. Conducting a bi-annual survey of the installation site is a good idea. Keep in mind that a solar systems lasts for more than 25 years and trees grow over time. Ensure that there are no trees around and that the solar panels are not blocked by shadow at any time during the day. This is possibly the most common cause of low voltage. The factors that could contribute to a low power problem are: Shading This is the most common type of problem and a few, quick, troubleshooting steps will help you find the source of the problem. If your solar system is not delivering sufficient power for which it is rated for, the resulting situation is called a low power situation. As the pv modules are connected in series, one failing pv module will shut down the entire system. It’s also possible that one solar panel in your pv array failed. Zero output is a common problem and in nine out of ten cases, it is due to a faulty inverter or charge controller. These two conditions which may require troubleshooting are: There are two failure modes which the solar system maybe experience. Two common problems that require troubleshootingĪs mentioned above, most of the problems are caused by the inverter and charge controller. However nearly every pv manufacturer has seen defects in solar panels over the past years, and I’ll also describe common quality issues that might shut down a pv module. For that reason, it’s most likely that a problem is caused by a defect in system components other than the panels, such as the solar inverter, charge controller, wiring or batteries. Quality solar panels are built and guaranteed to produce power for 25 years. Troubleshooting a solar (pv) systemīelow I will describe basic steps in troubleshooting a PV array. Common issues are zero power and low voltage output. This article describes how you can troubleshoot a solar system in basic steps. ![]() |
