how to install APC AP5203 KVM Console Extender

Step 1: Power down the Analog KVM Switch and the remote console before making any connections. Connect the AP5203 between the KVM switch and the remote console using the supplied cabling according to the user manual. Ensure that all connectors are firmly seated to maintain signal integrity over the extended distance.

Step 2: Power on the remote console and then the KVM switch. Verify that the video signal, keyboard input, and mouse movement are accurately transmitted to the remote screen and that control is responsive at the remote location. If you notice any garbled video or latency, recheck cable integrity and ensure the distance remains within the supported range.

Step 3: Test POST and BIOS-level access by rebooting a connected server from the remote console. Attempt to enter BIOS setup or perform a diagnostic run during the boot sequence to confirm that pre-boot access is functioning correctly across the extended link.

Step 4: Configure routing and control parameters on both the Analog KVM switch and the AP5203 so that input selection and switching commands are correctly transmitted to the target server or servers. Document the configuration for future maintenance and ensure consistency across all managed devices.

Step 5: Implement basic security practices for remote console access, such as restricting physical access to the remote console, enabling device-level authentication where available, and keeping firmware up to date on both the KVM switch and the AP5203. Regularly review access logs and monitor performance to maintain a reliable remote management setup.

Petite person's perspective
Color: Grey, Color: Grey
Full name on the box: Light Grey Bonded Leather/Mesh Air Executive Chair (Model: 43807) This review is from a petite female’s perspective I was browsing for couple months and this Serta chair stood out to me, mainly aesthetically. I don’t see many chairs in this color or style. It matched with the rest of my PC/desk setup. Positives -Seat is comfortable. -Lumbar support is good. It helps me sit very straight. -The casters were surprisingly easy to put in. I had to use some force with two of them though. They roll fine on carpet. -Easy assembly Neutral/Negatives -Paint of armrests is easily scratched. I accidentally scratched it while installing the back. -The black plastic caps used to hide the screws don’t fit well. The plastic inserts for hiding screws in arms don’t fit well either. It makes the chair appear cheap. (I will provide images) -Craftsmanship isn’t the best. Not noticeable from a distance though. -At lowest setting, my feet can’t touch the ground but being 4’11” it’s to be expected. -Height of the back is too high for my liking. I prefer a few inches shorter so I can tilt my head back to rest my neck. My fault for not realizing I should look into "mid-back chairs". -Head/top area is too firm. I prefer it to be squishy (e.g. Serta Smart Layers Verona or Siena). As another reviewer mentioned, don’t forget to remove the foam or cardboard behind the lumbar and head/shoulder. That is supposedly the last step when assembly is all done. **If you come across any issues/warranty, you contact TRUE INNOVATIONS, not Serta. (I will provide images)

***Serta should recall this chair!
Color: Grey
Serta quality and comfortable for office use only, casual home use isn't the same... the only reason I didn't give it 5 stars for ergonomics is that if you are not sitting upright in "office mode" and you want to slouch and relax, the seat makes you feel like you are always sliding forward in the chair? I assume that is because it's an "ergonomic" chair, but it is well built and worth the price in my opinion. ***Updated addition; after using the chair to work from home & casual use, it is still annoying to feel like it tilts forward unless you are sitting up perfectly straight! I have also noticed that if you get up or reposition yourself (due to the forward sliding) the seat height resets itself back up to the top!? So when you sit back down you have to lower the seat again... my last Serta chair never had these issues!! For the price point, this shouldn't be a chair I will be replacing after a few months - but not with another Serta! ****Second update = now 1 star! (Chair still looks new, I only work from home 1 day a week, and take great care of my things so there is no damage or even usage wear) After trying to make the best of this chair, it is even more annoying to use.. it now "groans" when any movement rocking back or forth... it still feels like it is forcing you to slide forward and feels like the chair wants your to fall out! Leaning back doesn't stay (no adjustment to keep from "leaning forward") so no matter what I do, I hate sitting in this chair more every day... and now I am very worried about buying another chair blind online! ***Serta should recall this chair! *****Third update = Chair still looks and feels brand new, but now randomly will make weird creaking and groaning noises with every movement and as an added bonus it randomly just sinks to the lowest level without warning!!! Typing away and it just starts sinking until it hits bottom! I don't know how an expensive chair could be so awful!!

Good chair, Hensley is more comfortable
Color: Grey, Color: Grey
Received chair in a large box and assembly was easy. Instructions call for 2-person assembly but I set out to do as much as I could by myself until someone else was available. No tools needed other than the Allen wrench provided. I assembled the chair in under an hour by myself. The 2 person portion of the assembly was for attaching the seat to the wheel assembly but I managed to attach it myself with some careful maneuvering. The chair is nice and comfortable enough, but I was spoiled by the comfort of trying a different Serta model (Hensley, now discontinued) ina store. I couldn't find that model anywhere else and the floor model was SOOOO comfortable with its Serta Smart Layers. I was hoping Bryce would be a close second. After trying Bryce for a few days, I'd say its a distant third. If I never met Hensley, Bryce might have a higher rating. Update: based on other reviews, I made covers for the armrests to prevent wear and peeling of the padding cover.
