Interface boards that an EGS2 board on an OSN 3500 can work with

Types of ports on an EGS2 board of an OSN 3500: 1. Each EGS2 board supports 1000Base-SX/LX/ZX/VX Ethernet optical ports, which support auto-negotiation and comply with the IEEE 802.3z standard. An EGS2 board uses hot-pluggable SFP optical ports, which support a maximum transmission distance of 550 m in case of multimode fibers and a maximum transmission distance of 10 km in case of single-mode fibers. You can also use an optical module that supports a maximum transmission distance of 40 km or 80 km as required. 2. An N3EGS2 board also supports 1000BASE-T RJ45 Ethernet electrical ports, which support 10M, 100M, or 1000M auto-negotiation. The board uses hot-pluggable SFP electrical ports, which support a maximum transmission distance of 100 m.

Port working modes supported by an EGS2 board on an OSN 3500: 1. GE electrical ports: auto-negotiation, 1000M full-duplex, 100M full-duplex, and 10M full-duplex (Only N3EGS2 boards support GE electrical ports.) 2. GE optical ports: auto-negotiation and 1000M full-duplex

Reset modes supported by an EGS2 board on an OSN 3500: 1. Warm reset: An N2EGS2 board supports a warm reset, which interrupts services. An N3EGS2 board supports a warm reset, which does not affect services.After an N2EGS2 board is replaced with an N3EGS2 board by using the board version replacement function, a warm reset is supported, which does not affect services. 2. Cold reset: supported. A cold reset interrupts services.

An EMS2 board on an OSN 3500 can work with the following types of interface boards: 1. Works with two ETF8 boards to receive and transmit FE signals over 16 electrical ports. 2. Works with two EFF8 boards to receive and transmit FE signals over 16 optical ports. 3. Works with an ETF8 board to receive and transmit FE signals over 8 electrical ports, or works with an EFF8 board to receive and transmit FE signals over 8 optical ports.

An EFT8 board on an OSN 3500 can work with the following types of interface boards: 1. Works with two ETF8 boards to receive and transmit Ethernet signals over 16 electrical ports. 2. Works with an EFF8 board to receive and transmit 8 channels of Ethernet optical signals and 8 channels of Ethernet electrical signals.
