• Cumhachd: A dedicated power outlet with proper grounding is recommended.
• Fionnarachadh: Ensure at least 5 cm (2 inches) of clearance at the front and rear for airflow.

5.2 Stàladh raca

The EX4200-24P is designed for installation in a standard 19-inch equipment rack.

1. Ceangail na camagan raca a tha air an toirt seachad ri taobhan an suidse a’ cleachdadh nan sgriothan a tha air an toirt seachad.
2. Align the switch with the rack posts and secure it using appropriate rack screws.

5.3 Ceangal cumhachd

1. Connect one end of the power cord to the AC power connector on the rear panel of the switch.
2. Ceangail ceann eile a’ chorda cumhachd ri socaid dealain le talamh.
3. The switch will power on automatically. Observe the system status LEDs for initial boot-up.

5.4 Ceanglaichean lìonra

1. Ceangail càbaill Ethernet bho na h-innealan lìonra agad (coimpiutairean, fònaichean IP, puingean ruigsinneachd gun uèir) ris na puirt RJ-45 air a’ phannal aghaidh.
2. For uplink connections to other switches or routers, insert appropriate SFP/SFP+ transceivers into the uplink module slot and connect fiber or copper cables as required.
3. For initial configuration, connect a console cable from your management workstation to the console port on the rear panel.
