Cisco FSP 40km optical module
Cisco SFP-10G-ER40 Compatible SFP+ transceiver supports up to 40km over OS2 SMF via an LC duplex connector. This transceiver is compliant with SFF-8431 and SFF-8432. The industry-standard Cisco Small Form-Factor Pluggable (SFP) Gigabit Interface Converter (Figure 1) links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Featuring low power consumption. The SFP-1040-Dxx is a DWDM 10G SFP+ optical module. It is available for all 45 DWDM 100GHz ITU grid wavelength channels. 3-2012 Clause 88 standard IEEE 802. [pdf]
What does it mean when a switch restricts network segment access
Port-based network access control (PNAC) blocks access to a network by denying communication between an unauthorized device and the network. When an unauthorized device attempts to connect to a network port, the switch or router that manages the port will deny access to the network. NAC verifies who and what is connecting, checks whether a device meets security. Segmentation is the practice of dividing a network into smaller parts called segments to improve security, performance, manageability, and compliance. Of organizations say segmentation is a priority. Enabling this feature keeps track of permitted source MAC addresses and restricts the number of MACs that can use a specific port. [pdf]
Should the network cabinet be grounded
Proper grounding is essential for any electrical system, including server racks. Grounding provides a safe path for electrical current to flow in the event of a fault or surge, protecting both equipment and personnel from electrical shock. The whole structure consists of a metal circuit, a protect bus, and a ground wire. Network hardware is connected to PDUs and constantly. Below is a comprehensive guide for implementing effective bonding and grounding systems in data centers. [pdf]FAQs about Should the network cabinet be grounded
