How to install Cisco 16-Port Async Serial NIM

Installing the Cisco 16-Port Async Serial NIM on a Cisco 4000 Series ISR is designed to be straightforward and minimally disruptive. Follow these general guidelines to ensure a smooth deployment within a supported Cisco IOS environment.

  • Verify compatibility: Confirm that your router model is a Cisco 4000 Series ISR and that the chassis has an available NIM slot compatible with Async Serial modules. Check software requirements to ensure IOS or IOS XE supports the NIM in your network design.
  • Prepare for installation: Plan a maintenance window if possible. While the NIM is hot-swappable, coordinate changes to minimize impact on active sessions. Gather the necessary serial cables, labeling tools, and device inventories to map each port to its intended terminal server or console device.
  • Install the module: Power down only if the router design requires it, or use hot-swap procedures if supported by your hardware. Insert the 16-Port Async Serial NIM firmly into the designated slot until it seats completely. Secure any latches or screws as required by the chassis design, then reseat the router cover if it was removed.
  • Power on and verify: Reconnect power if needed and verify that the NIM is recognized by the Cisco IOS. Use show commands to confirm port presence and status, such as a quick check of interface listings for the 16 serial ports.
  • Configure and map ports: In the IOS configuration, assign each of the 16 ports to the appropriate terminal server connections. Define baud rates, parity, stop bits, and any device-specific parameters as required by your serial devices. Implement access control, port mappings, and session policies to ensure secure and reliable console access.
  • Test and monitor: Initiate test sessions to validate connectivity for each terminal server connection. Monitor port status, error counters, and performance metrics using CLI or SNMP-based tools to ensure stable operation under expected loads.

Ehh
Size: Medium, Color: Multicoloured E-(5-pack)
Very thin, still comfy but very thin material. Super soft though. I've worn and washed and they have held up but I won't be repurchasing bc these are so thin

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.
