A method that includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

Method and apparatus for maintaining cooling of modular electronic system during module removal

In one embodiment, a method includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

In one embodiment, an apparatus is disclosed comprising a cable management bracket and a cable guide connector configured to engage a slot of a networking chassis having a length extending along a first axis. The cable guide connector comprises a center section configured to slide within the slot along the first axis and having an aperture configured to receive a retainer to secure the cable guide connector by compression at a selected position along the length of the slot. The cable guide connector further defines a plurality of apertures configured to engage a protrusion of the cable management bracket and defines a plurality of selectable angles at which the cable management bracket can be positioned relative to a second axis that is perpendicular to the first axis through which the slot extends.

Adjustable cable management slide and direction control for optimized routing

In one embodiment, an apparatus includes an optical module comprising a first end for insertion into a network device and a second end extending from the network device when the optical module is inserted into the network device, and a thermal protective layer extending over a portion of the second end of the optical module, the thermal protective layer preventing direct contact with an external surface of the optical module during removal of the optical module from the network device. The thermal protective layer exposes a portion of the external surface of the second end of the optical module to allow heat to be released from the external surface of the optical module.

Thermal protection for modular components in a network device

In one embodiment, a device in a modular networking rack determines an online insertion and removal (OIR) time for a particular device module of a plurality of device modules contained within the modular networking rack. The device determines an OIR time for the plurality of device modules based on the OIR time for the particular device module and provides an indication of the OIR time for the plurality of device modules for display to a user.
