![]() When this happens, both heater core hoses should be hot. The heated coolant then warms up the air and circulates it through the interior of your car. The heater hoses pass coolant from the engine to the heater core. To do this, both heater hoses should be hot. It does this by heating the air that passes through it. The heater core is responsible for the overall temperature of your vehicle's interior. If you purchase something through a link on this page, we may get a commission, so thank you! In addition, we will answer other frequently asked questions about heater core hoses, so read on!īefore you continue reading, let us say we hope you find the links here useful. This article will take a closer look at the purpose of heater core hoses and the warning signs of an issue. Troubleshooting a heater core or any mechanical part in a vehicle can be challenging. In addition, if the heater hoses are cold, this is also a sign of clogged hoses. If one is noticeably hotter than the other, then there could be a clog in the hose. To properly warm the interior of your vehicle, then both heater hoses should be hot. However, if your heater isn't working correctly, could it be due to both heater hoses being hot? Let's look to see if this is a concern or not. It would be helpful if you describe what's exactly in your 6500 now, what particular 3750 model is your alternative solution, whether it's stacked, and if so, with what, and how the 3750 connects to the 6500.A heater core plays an essential role in keeping your vehicle's interior warm. It's also a classic bus card, which depending what else is in your chassis, could degrade performance. It doesn't well support busy ports, often the case with server ports. I want to connect approximatly 10 application servers to the network.Ĭan I connect the servers directly to the catalyst 6500 switches using WS-X6148E-GE-TX line cards? The other option is to use access switchs and then connect the servers to the catalyst 6500 through access switch(Catalyst 3750). We are using CISCO Catalyst 6500 switches as collapsed core/distribution switches (2 layer architecture). 16 Gbps bandwidth.īTW, if you had a 6724/6748 line card, that would be the best way to connect the servers to the 6500. Additionally, a 3750-X may also perform better connected to a 6500 via dual 10g links than devices connected using a 6148 as it has 20 Gbps vs. Personally, working with gig and 10g ports, in a distribution/core role, I recommend preserving compact mode. The reason I asked what else is in the chassis, if you already have any other classic bus cards in the chassis, adding another classic bus cards won't degrade the whole chassis further. Lastly, as Leo mentions, you'll want to avoid sharing ASICs on a 6148 cards (I recall it's one ASIC per 8 ports).īasically, again, you can use a 6148 but it can be very degrading to overall performance of the 6500, and since this is your core device, is that acceptable? Additionally, any classic bus card precludes the whole chassis from running in compact mode, halving (or more) the supervisor's PPS rate. A classic bus card and a fabric card can't even directly communicate, they have to bounce data transfers through the supervisor. ![]() It helps a little, but there's still insufficient information as you haven't described what exactly your 6500 is currently populated with.įor example, if you're going to have 15 pairs of 10g links on the 6500, this implies some 6700 series 10g cards, all of which are fabric only cards.
