This is a blank keystone patch panel for a 19 in rack, in five sizes: 12 or 16 ports in 1U, 24 or 32 ports in 2U, and 48 ports in 3U. The ports are empty keystone openings, numbered on the face, so you load the panel with whatever the rack needs, from Cat6 and Cat6A jacks to shielded jacks, fiber adapters, F-81 coax couplers, and HDMI, in any mix, and swap a port later without touching the rest. The panel is 16-gauge SPCC steel with a black powder coat, flat at 0.45 in deep, and it mounts in any standard 19 in rack or enclosure. It's sold individually, without jacks. For the jacks, the KEY6-90 and MIG6A-90 for unshielded Cat6 and Cat6A, the KEY6-SHD and MIG6A-SHD for shielded, the CAT8SH-KEY for Cat8, and the KEYCAA for coax; for a panel that comes with the Cat6 blocks already in it, the PP6-12NR, PP6-24NR, and PP6-48NR. Features Blank keystone, any mix. Standard keystone openings take RJ45, fiber, coax, and HDMI inserts side by side. Five sizes. 12 or 16 ports in 1U, 24 or 32 ports in 2U, 48 ports in 3U. Pre-numbered ports. Printed on the face. 16-gauge SPCC steel, black powder coat. 19 in wide, 0.45 in deep. Standard 19 in rack mount. Sold individually. Jacks not included. Where It Fits It suits data centers, server rooms, and network closets where one panel has to carry copper and fiber, or Cat6 and Cat6A, or data and coax, without buying a separate panel for each. It suits structured cabling crews who terminate at the keystone jack on the bench and snap it into the panel, so a failed port is a jack swap and not a panel. Shielded plants use it with shielded keystones, and so do AV racks that need HDMI and F-81 alongside the Ethernet. A rack that's growing a few ports at a time is a candidate, since the empty openings take a blank insert until they're needed. It goes with the keystone jacks, the bulk cable, and the punch-down tool from the copper and fiber collections. For unshielded Cat6 and Cat6A jacks, the KEY6-90 and MIG6A-90. For shielded, the KEY6-SHD and MIG6A-SHD. For Cat8, the CAT8SH-KEY. For coax, the KEYCAA, KEYCAB, KEYCAD, and KEYCAE. For a preloaded Cat6 panel, the PP6-12NR, PP6-24NR, PP6-48NR, and PP6-96NR. Good to Know A blank panel costs less than a preloaded one but the jacks add up, so price the whole panel before you choose: at 24 ports and up, a preloaded 110 panel is usually cheaper per port, while the blank panel wins when the mix is varied, the count is small, or you want every port to be a replaceable jack. Terminate each jack before you snap it in, since there's more room to work with the jack in your hand, and leave enough slack behind the panel to pull a jack out and re-terminate later. Standard keystones snap in from the front or the back depending on the jack; most go in from the back with the latch up, and come out by pressing the latch with a small screwdriver. At 0.45 in deep the panel has no rear bar, so tie the incoming bundle to the rack's rear rails or a separate strain relief bar so the weight is never on the jacks. Put a blank insert in any port you don't use, since an open keystone hole collects dust and invites a finger. Mind the bend radius behind a 48-port 3U panel; that's a lot of cable in a small space. A shielded keystone in a steel panel bonds to the panel through its own shell, but the panel still has to be bonded to the rack and the rack to the grounding busbar for the shield to do anything. The 3U panel is 5.25 in tall, the 2U 3.5 in, the 1U 1.75 in; check the rack has the units free before you pick a size.
