Of the 3 HEs front are only 2 with Full Size - 19 inch devices to operate in the 3 HE the extract against the device comes installed so that only devices with Are all 3 HEs there is no way a cable to get back above and below the HES to the housing and can no way inside the housing cable weiterzubekommen. The 19-inch sheets are quite far forward, I have 1 patch panel and switch 1 and even with the shortest patch cables, it is only with pressing and bonding possible all 24 cable so the unterzubekommen also approaching the door. Because of my limited space acceptable, but not beautiful.
